The present disclosure, in some embodiments thereof, relates to analyzing the actions of users during endovascular procedures, automatic correction to the actions of users during endovascular procedures, and decision support and automation during endovascular procedures.
Interventional radiology has gained popularity in many medical fields, such as endovascular intervention techniques including in the endovascular treatment of acute conditions (e.g., ischemic stroke, trauma, gastrointestinal tract bleeding, and aortic aneurysm) and elective embolization (e.g., coil embolization repair of aneurysm and embolization of uterine and prostate arteries). Many different medical devices have been developed for these treatment modalities, and their effective use is essential to the success of treatment. Accordingly, training and supporting interventional radiologists as well as maintaining their high skill is vitally important to the success of treatment.
Gathering and analyzing information related to actions of users for controlling medical devices, including endovascular devices, during invasive procedures may improve the quality and success rate of invasive procedures. The analysis can be used, for example, to compare the actions of the interventional radiologist to their previous action, to other radiologists working in the same medical field, or to gold standard values. The comparison may be used to improve radiologist's actions by providing them with suggestions for decision making, also known as decision support. Furthermore, such an analysis may be used, for example, as part of a training protocol to provide a safe and unified practice for users such as interventional radiologists.
Additionally, the gathering and analyzing of information may be used to influence an automatic correction to actions of a user of an endovascular device during an invasive procedure. Further, the information gathered and analyzed may be used to automate an endovascular procedure. For example, information from medical images and/or sensors can be used to automate a procedure. The user may identify certain information or parameters associated with the procedure or the outcome and the endovascular device may be automated to perform actions corresponding to the information or parameters.

It is contemplated that other communication systems may be used for wireless communication between control device 110 and sensor 130.
As shown in step 210, the method may include receiving indications of a plurality of actions of a user for controlling an endovascular device during an invasive procedure. The indications of the plurality of actions may be received from the control device, may be read from memory, may be received from an external device, or received from any other memory device or processor. The plurality of actions may include a movement or transformation of an endovascular device.
For example, the endovascular device may be a deflectable catheter or a bendable guide wire (e.g., controllable catheter or controllable guide wire). One of the plurality of actions may be an action configured to cause at least one distal portion (e.g., distal tip) of an endovascular device to bend. The bending of the distal portion (e.g., distal tip) of the endovascular device may permit the endovascular device to be navigated through tortuous anatomy, such as blood vessels, or other hollow body structures.
In another example, the endovascular device may be an endovascular stent retriever (e.g., controllable stent retriever) or an adjustable mesh device. One of the plurality of actions may be an action configured to cause a distal portion of the endovascular device (e.g., a mesh segment of the stent retriever or of the adjustable mesh device) to expand or contract. As used herein, expansion of a distal portion of the endovascular device may refer to an increase in the size or in at least one dimension of the endovascular device (e.g., an increase in an outer diameter, inner diameter, height, length or width of the distal portion of the endovascular device). Further, contraction may refer to a decrease in the size or in at least one dimension of the distal portion of the endovascular device, also referred to as collapse or relax. In some embodiments, the distal portion of the endovascular device may include a structure configured to expand and contract while the remainder of the device remains unchanged, such as an expandable mesh or stent or an inflatable balloon.
Another one of the plurality of the actions may be an action configured to control a magnitude of the expansion and/or a magnitude of the contraction of a distal portion of the endovascular device (e.g., a mesh segment of the stent retriever or of the adjustable mesh device). The expansion of the distal portion of the endovascular device may assist in capturing a clot, such as a blood clot in a body structure (e.g., in a blood vessel). Expansion of the distal portion of the endovascular device may also assist in support or remodeling of a body structure (e.g., blood vessel) during embolization of an aneurysm. Additionally, or alternatively, expansion of the distal portion of the endovascular device may enable mechanical dilation of vasospastic body structures (e.g., blood vessels). The expansion of the distal portion of the endovascular device (e.g., of a mesh segment) may also be used to treat arterial stenosis. The contraction of the distal portion of the endovascular device (e.g., of a mesh segment) may assist in safely removing the endovascular device from the body structure (e.g., blood vessel), and subsequently the body of the patient.
In another embodiment, the endovascular device may be a stent. One of the plurality of actions may be an action configured to cause a detachment of a stent in a body structure (e.g., blood vessel) of a patient.
According to some embodiments, the endovascular device may be an intraluminal device. In some embodiments, the endovascular device may be an endovascular coil. One of the plurality of actions may be an action configured to cause a detachment of the coil in a body structure of a patient (e.g., in a body lumen). In procedures such as coil embolization, the coil may be detached after packing an aneurysm to provide blood flow through a blood vessel (e.g., an artery or vein) and prevent blood flow through the aneurysm.
In some embodiments, the endovascular device may be an endovascular catheter or an endovascular coil. One of the plurality of actions may be an action configured to cause a portion of the endovascular device to heat up. For example, an endovascular catheter may be heated in the body of a patient to provide rapid and controlled rewarming in cases of hypothermia. As another example, an endovascular coil may be heated to cause a detachment of an endovascular coil during coil embolization.
In another embodiment, the endovascular device may be an endovascular neuromodulation device. One of the plurality of actions may be an action configured to cause an electric current to flow between two electrodes positioned within the body structure (e.g., blood vessel). Another one of the plurality of actions may be an action configured to cause a difference of electric potential between two electrodes positioned within a body structure (e.g., blood vessel). The actions associated with an endovascular neuromodulation device as discussed above may be configured to be performed at the same time, or simultaneously.
In some embodiments, one of the plurality of actions may be an action configured to cause a movement of the endovascular device, such as advancing forward into or backward out of the body structure (e.g., a blood vessel or other hollow body structure), or advancing one endovascular device over another endovascular device (e.g., movement of a catheter, such as an aspiration catheter or microcatheter, over a guide wire or a stent retriever).
As shown in step 220, the method may include receiving an indication of a preceding status for each action of the plurality of actions. The preceding status may occur immediately before the action, where immediate may include, for example, occurring within 1, 2, 3, 4 or 5 minutes before the action. For example, the preceding status may occur less than 1 second before the action, less than 5 seconds before the action, less than 10 seconds before the action, less than 15 seconds before the action, less than 20 seconds before the action, less than 30 seconds before the action, less than 45 seconds before the action, less than 60 seconds before the action, less than 90 seconds before the action, less than 120 seconds before the action, less than 150 seconds before the action, or less than 180 seconds before the action. In some embodiments, the preceding status may occur within 1 second to 2 minutes before the action.
In some embodiments, the preceding status may include a physical state of a patient. The physical state of a patient may include, for example, blood flow in a particular body structure (e.g., a blood vessel), a diameter of a particular portion of a particular body structure (e.g., a blood vessel), a blood perfusion to a particular tissue, a size of a body structure (e.g., a blood vessel) at a site of treatment, a location of a site of treatment, other anatomical or physiological descriptors of the patient, or any combination thereof. The physical state of a patient may further include information related to a clot in a body structure (e.g., in a blood vessel). The information related to the clot may include, for example, the type of the clot, the location of the clot within the body structure (e.g., a blood vessel), the size of the clot, or any combination thereof.
In other embodiments, the preceding status may include the state of the endovascular device. The state of the endovascular device may include, for example, a bending curvature at a distal portion of the endovascular device (e.g., at a distal tip), a degree of expansion or contraction of a distal portion of the endovascular device (e.g., a mesh segment), a temperature of the device, a flow of electrical current to flow two electrodes or points, a detachment of the device or part of the device in the body structure, and other physical and/or chemical descriptors of the endovascular device. The state of the endovascular device may further include a degree of opening associated with the endovascular device (e.g., of a mesh segment of the endovascular device), and/or a position of the endovascular device within a body structure.
In some embodiments, the preceding status may include an indication of an anatomical location of a portion of the endovascular device. The preceding status may include a location of a portion of endovascular device in relation to a clot, to an aneurysm, or to a narrowing of a body structure (e.g., blood vessel). In some embodiments, the preceding status may include a location of a portion of endovascular device in relation to a portion of a second endovascular device. Additionally, the preceding status may include a location of a portion of endovascular device in relation to a branch in a body structure (e.g., blood vessel).
A medical image captured before a particular action of the plurality of actions may be received and analyzed to determine the preceding status of a particular action. A medical image may be an angiogram, a computed tomography (CT) image, a magnetic resonance image (MRI), an X-ray, or an ultrasound image. A convolution of at least part of the medical image may be calculated. The value of the calculated convolution may be used to determine the preceding status of the particular action. In some embodiments, the medical image may be displayed on a display, for example, the peripheral device 140 of
A sensor reading from a sensor may be captured before a particular action of the plurality of actions and analyzed to determine the preceding status of the particular action. In some embodiments, the sensor 130 may be connected to the endovascular device system 100, as shown in
As shown in step 230, the method may include generating data related to the plurality of actions of the user. In some embodiments, the generated data may include a type of action and the preceding status for each action. The data may be generated based on the received indications of step 210. In another embodiment, the generated data may further include an outcome for each of the plurality of actions. An outcome for an action may be a predicted next action based on the current action.
The outcome may be an immediate outcome after the action, where immediate may include occurring, for example, within 1, 2, 3, 4 or 5 minutes after the action. For example, the outcome may occur less than 1 second after the action, less than 5 seconds after the action, less than 10 seconds after the action, less than 15 seconds after the action, less than 20 seconds after the action, less than 30 seconds after the action, less than 45 seconds after the action, less than 60 seconds after the action, less than 90 seconds after the action, less than 120 seconds after the action, less than 150 seconds after the action, or less than 180 seconds after the action. In some embodiments, the outcome may occur within 1 second to 2 minutes after the action.
In some embodiments, the outcome may include a modification to a physical state of a patient, as discussed above. In other embodiments, the outcome may include a modification to a state of the endovascular device, as discussed above.
The outcome may have an effect on a prognosis. A prognosis may include the speed of revascularization, or restoration of blood flow in a body structure (e.g., a blood vessel). For example, an action or a plurality of actions that correspond with efficient and/or quick clot retrieval may enable fast revascularization. An action or a plurality of actions that correspond with less efficient and/or slower clot retrieval may lead to slow revascularization. A fast revascularization may allow a patient to heal and/or recover with less long-term damage.
Another example of a prognosis may include the blocking of an aneurysm. An action or a plurality of actions that correspond with support of a body structure (e.g., blood vessel) during embolization of an aneurysm without blocking blood flow may enable fast recovery and successful treatment of an aneurysm. An action or a plurality of actions that correspond with blocking of blood flow during embolization of an aneurysm or with improper vessel support during embolization may lead to long-term damage and/or the need for a second corrective invasive procedure.
In some embodiments, a medical image captured after a particular action of the plurality of actions may be received and analyzed to determine the outcome of a particular action. A convolution of at least part of the medical image may be calculated. A value of the calculated convolution may be used to determine the outcome of a particular action.
In other embodiments, a sensor reading from the sensor may be captured after a particular action of the plurality of actions and analyzed to determine the outcome of the particular action.
In some embodiments, the generated data may further include a magnitude for each action, a magnitude of a force exerted as a result of an action, a setting of the control device associated with an action, a measure of a deviation from a constant pushing speed, and/or a measure of deviation from a constant pulling speed. The generated data may also include settings of the control device, where the settings store parameters associated with performing each action. There may be a finite number of settings of the control device associated with a single action. In other embodiments, there may be an infinite number of settings of the control device associated with a single action.
As shown in step 240, the method may include analyzing the data to determine a relation between the preceding status for each action and the plurality of actions. In some embodiments, the data may be analyzed to determine a relation between a preceding status for an action, the action, and the outcome of the action.
For example, the data may be used to determine a correlation between a particular preceding status and an action. This can be used to predict the occurrence of an action based on a particular preceding status. As another example, the data may be analyzed to determine a relation using data regressions, machine learning algorithms, and/or other data and/or statistical analysis tools.
In some embodiments, the captured medical image or sensor reading may be used in the determination of an outcome of an action, as discussed above. In some embodiments, the relation between the preceding status for each action, the plurality of actions, and/or the outcome may be based on the magnitudes of the plurality of actions, a magnitude of a force exerted as a result of an action, the settings of the plurality of actions, and/or the measures of deviation for the plurality of actions.
As shown in step 250, the method may include providing an evaluation of the user. For example, the evaluation of the user may be a comparison of the action to stored settings of what the action should be. An evaluation of the user may be a score or rating of the efficiency, precision, and/or accuracy of the action performed by a user. Furthermore, the evaluation of the user may be rating of the action performed by the user on a scale. Additionally, or alternatively, the evaluation of the user may be an evaluation of the user's performance of an action or of a procedure. A procedure may be evaluated as a combination of actions, where each action is a step in the procedure. In some embodiments, the evaluation of the user may be reported to the user via a user interface, such as the peripheral device 140 of
In some embodiments, the steps of the method shown in
In some embodiments, the steps of the method shown in
The evaluation of the user may be configured to enable a device to analyze a prospective action of a second user. The evaluation of the first user may cause a correction to a prospective action of the second user. The correction may include impacting the endovascular device in response to the prospective action. For example, the prospective action of the second user may be an action utilizing a similar type of endovascular device and/or for the same type of medical indication.
For example, the prospective action of the second user may be an action configured to expand the distal mesh segment of an endovascular device. However, the evaluation of the first user may identify that the action following a shared preceding status between the first and second user should be a movement of the endovascular device forward into the body structure, and not an expansion of the distal mesh segment of the endovascular device. Thus, the evaluation of the user may cause the endovascular device to move forward into the body structure instead of expanding, effectively correcting, or overriding the action of the second user.
The evaluation of the first user may act as a template or gold standard to assist and/or guide a second user when performing the same or a similar invasive procedure as the first user. Accordingly, evaluation of the first and second users may act as a template or gold standard to assist and/or guide any subsequent user when performing the same or a similar invasive procedure as the first or second users. A correction to a prospective action may be a correction in response to a deviation from the prospective action from a pattern determined based on the data. The pattern may be determined by actions associated with a template or gold standard.
In some embodiments, the evaluation of a single user may include a comparison to the evaluations of actions of a group of users, wherein the group of users may comprise any number of users (e.g., 3, 4, 5, 10, 15, 20, 25, 50, 100 or more), where the single user is not included in the group of users. In other embodiments, the single user may be included in the group of users. For example, evaluations may be provided for a group of users. The evaluations may be set or considered as the template or gold standard for performing a type of invasive procedure. While the single user is performing the same type of invasive procedure, the actions of the single user may be compared to the evaluations of the group of users. The comparison may be used to provide an evaluation of the single user, where the evaluation is effectively a comparison to a template or gold standard.
In other embodiments, the steps of the method shown in
As shown in step 310, the method may include receiving an indication of a magnitude and a type of an action of a user for controlling an endovascular device during an invasive procedure. According to some embodiments, the action may be a continuous action. According to other embodiments, the action may be a non-continuous action. The magnitude of an action may include a direction, a curvature, a net force, a speed, or other characterizations of a transformation of an endovascular device. The type of an action may be a characterization of an action. For example, a type of action may be an expansion of the distal portion of an endovascular device (e.g., a mesh segment). The magnitude may then be the degree of expansion or the force exerted on a body structure (e.g., on a blood vessel).
As shown in step 320, the method may include determining a correction to the magnitude of the action. For example, the action may be a movement of an endovascular device in a first direction. A determined correction may include identifying that the movement of the endovascular device should be in a second direction, as opposed to the first direction.
In some embodiments, an action may be an expansion of a mesh of an endovascular device (e.g., of a stent retriever or of an adjustable mesh device). A determined correction may include identifying that the mesh segment of the device is expanded to a size which may be too small to capture a clot in a body structure (e.g., blood vessel) or to dilate a narrowing in a body structure (e.g., blood vessel).
In some embodiments, an action may be a contraction of a mesh of an endovascular device (e.g., of a stent retriever or of an adjustable mesh device). A determined correction may include identifying that the mesh segment of the device is expanded to a size that may be harmful to the body structure (e.g., blood vessel).
The determined correction may be based on the type of the action and one or more parameters associated with the type of action. Each parameter of the one or more parameters may be associated with a different magnitude of an action. The parameters may be stored correlations between a type of action and a desired magnitude of the action, where the parameters are stored in a memory device. The memory device may be part of a control device 110 or of peripheral device 140 of
In some embodiments, the determination of the correction may further be based on a standard of care. For example, in embolization of an aneurysm, the standard of care may include a packing density (e.g., of coils) of greater than or equal to 19%. The packing density included in the standard of care may vary based on factors such as, but not limited to, the size, type, and location of the aneurysm. The determination of the correction may be based, for example, on a comparison of a packing density during a coil embolization procedure to the packing density required by the standard of care.
As shown in step 330, the method may include overriding the action of the user based on the determined correction to the magnitude. For example, an override may be configured to modify a particular magnitude when the action is configured to exert a net force of the particular magnitude on a core wire (e.g., a control wire) of the endovascular device. According to some embodiments, and without limitation, the core wire may be a wire capable of causing an expansion and/or a contraction of a mesh segment of a controllable endovascular device. According to other embodiments, and without limitation, the core wire may be a wire capable of causing a controllable bend in at least one distal portion (e.g., distal tip) of an endovascular device.
Other examples of overriding may include modifying one or more of: a force in a direction of movement, a magnitude of electric current flow, a rate of heating, a temperature, a curvature of a distal portion (e.g., distal tip), a formation (e.g., expansion or contraction) of a distal portion of the endovascular device (e.g., mesh segment), a speed of movement, a distance of movement, a direction of movement, a rate of detachment, and/or a location of detachment. Another example of overriding may include smoothing a time series of magnitudes where the action is associated with a time series of magnitudes (e.g., pulsatile motion, such as but not limited to, repeated expansion and contraction of a mesh segment for integration of a clot).
In some embodiments, an action may be associated with a first parameter of the control device. The override may be configured to avoid the action associated with the first parameter of the control device and to cause a second action associated with a second parameter of the control device.
For example, and continuing the coil embolization example discussed above, the action may be a detachment of the coil in an embolization. However, the determined correction may indicate that the packing density of the coil in the aneurysm has not reached a packing density defined by the standard of care. Accordingly, the override may include preventing the action, where the action is the detachment of the coil in the aneurysm, and instead cause the coil to continue filling the aneurysm.
In some embodiments, the correction to the magnitude of the action to the user may be reported to the user. The correction may be reported to the user, for example, via a user interface or a display, such as the peripheral device 140 of
As shown in step 340, the method may further include receiving an indication of a preceding status of the action. The correction determined in step 320 may then be based on the type of action, the preceding status, and/or on one or more parameters associated with the type of action. The overriding of step 330 may be based on the determined correction that includes the preceding status in the determination.
As shown in step 350, the method may further include receiving an initial reaction to the action in a first time period. An initial reaction to the action may be a resistance due to the endovascular device interacting with a narrowed body structure, such as but not limited to, a narrowed blood vessel, or resistance due to the endovascular device interacting with a clot (such as a blood clot). In another example, an initial reaction to the action may be a speed that the endovascular device travels through a body structure, such as but not limited to, a blood vessel. According to one embodiment, the method may further include receiving a reaction to the action in a second, third, fourth, fifth or more time periods.
After receiving the initial reaction, the correction determined in step 320 may then be based on the type of action, the initial reaction to the action, and/or on one or more parameters associated with the type of action. In other embodiments, the correction determined in step 320 may be based on the type of action, the preceding status, the initial reaction to the action, and/or on one or more parameters associated with the type of action. The overriding of step 330 may be based on the determined correction that includes the preceding status and the initial reaction in the determination. In other embodiments, the overriding of step 330 may be based on the determined correction that includes the initial reaction and not the preceding status in the determination. The overriding of the action 330 may occur after the first time period. Furthermore, the overriding of the action 330 may occur after a second, third, fourth, fifth or more time periods.
As shown in step 410, the method may include receiving a medical image captured prior to or during an invasive procedure. The at least one medical image may be captured prior to the procedure showing a condition of a site in the patient's body to be treated during the procedure. Prior to an invasive procedure may refer to a time period before the invasive procedure is performed, before an endovascular device is inserted into the patient, and/or before the endovascular device reaches a certain location in the body of the patient. The method may include analyzing the medical image to detect a body structure and/or a portion of an endovascular device in the body structure, as shown in step 420.
The analyzing of the medical image may include calculating a convolution of at least part of the medical image. The calculated convolution may be used to detect a body structure and/or a portion of an endovascular device in the body structure. The medical image may be analyzed to determine a magnitude or direction of a force necessary for an action. In other embodiments, the medical image may be analyzed to detect an aneurysm in the body structure. In some embodiments, the medical image may be analyzed to detect a narrowing in a blood vessel or occlusion in a blood vessel. In other embodiments, the medical image may be analyzed to detect tortuous anatomy.
As shown in step 430, the method may include selecting a recommended action for controlling the endovascular device during an invasive procedure. The recommended action may be selected based on the detected body structure and/or the portion of the endovascular device in the body structure. The selection of the recommended action may be based on stored parameters associating a state of the detected body structure and/or the detected portion of the endovascular device and a desired action.
Recommended actions may include actions that transform the endovascular device. Examples of transformations include, but are not limited to, exerting a magnitude of a force on the endovascular device, changing a magnitude of a force exerted on the endovascular device, causing a flow of electric current between two electrodes positioned within a body structure, causing a difference of electrical potential between two electrodes positions within a body structure, heating up a portion of the endovascular device, bending a distal portion of the endovascular device, expanding or contracting a distal portion of an endovascular device, and other movements or physical alterations of the endovascular device. In some embodiments, the recommended action may include a repetitive action, such as a pulsatile motion (e.g., repeated expansion and contraction, where the repeated expansion and contraction may be for a predetermined time period) of a distal portion of an endovascular device (e.g., of a mesh segment of an endovascular device).
In some embodiments, the medical image may be analyzed to identify a curvature of a body structure. The recommended action may include bending of at least one distal portion of an endovascular device (e.g., by exerting a force on a core wire of the endovascular device), where the curvature of the bending is determined by the curvature of the body structure.
In other embodiments, the medical image may be analyzed to identify a branching of the body structure to at least two branches. One of the branches may be selected and a curvature may be determined based on the branch. The recommended action may include bending of at least one distal portion of an endovascular device (e.g., by exerting a force on a core wire of the endovascular device), where the curvature of the bending is determined by the determined curvature.
In some embodiments, the medical image may be analyzed to detect a clot in the body structure and the recommended action, such as a degree of expansion of a distal portion of the endovascular device or a pulsatile motion of the endovascular device, may be selected further based on the clot (e.g., such as on the type of clot, its location, and its size).
In other embodiments, the medical image may be analyzed to detect a degree of packing in an aneurysm and the recommended action, such as a detaching of the coil, may be selected further based on the degree of packing. Furthermore, the medical image may be analyzed to detect an aneurysm in a body structure.
Furthermore, the medical image may be analyzed to detect a narrowing in the body structure, such as during vasospasm or atherosclerosis. The selection of the recommended action may be further based on the narrowing of the body structure, such as for example, on the type and location of the narrowing.
In other embodiments, the medical image may be analyzed to determine a likelihood of an impending change in a spatial arrangement of parts of the endovascular device to an undesired spatial arrangement. A recommended action may be selected based on the reduction of a likelihood of the impending change.
In some embodiments, a recommended action may include expanding or contracting a distal portion of an endovascular device (e.g., a mesh segment by e.g., exerting a force on a core wire of the endovascular device). The expansion or contraction may be to a particular formation, and the particular formation may be determined based on the analysis of the medical image. For example, the analysis of the medical image may determine a diameter of a narrowed body structure (e.g., a blood vessel). Accordingly, the recommended action may be a contraction of an endovascular device to a desired diameter based on the diameter of the narrowed body structure (e.g., a blood vessel). This may allow the endovascular device to advance through tortuous anatomy in the body of a patient. According to some embodiments, the recommended action may be a contraction of an endovascular device to a desired diameter to allow the endovascular device to retract safely from the body structure (e.g., blood vessel) of a patient.
Furthermore, the medical image may be analyzed to determine a recommended action involving moving the endovascular device according to one or more of the following: a speed of movement of the endovascular device, a distance of movement of the endovascular device, a direction of movement of the endovascular device, and/or a prevention of a particular movement of the endovascular device.
In some embodiments, a second endovascular device may be introduced and/or present in the body structure. The medical image may be analyzed to detect the second endovascular device in the body structure. The selection of the recommended action for controlling the first endovascular device may be further based on the state and/or location of the second endovascular device, and vice versa.
In other embodiments, the medical image may be analyzed to detect a portion of the second endovascular device in the body structure. The selection of the recommended action for controlling the first endovascular device may be further based on the detected portion of the second endovascular device. The detected portion of the endovascular device (or the second endovascular device) may include one or more of the following: a proximal marker, a distal marker, a catheter marker, a sheath marker, an aspiration catheter marker, a marker on a bendable portion of the second endovascular device, and/or a marker on an expandable portion of the second endovascular device.
In other embodiments, the medical image may be analyzed to detect a portion of one or more additional endovascular devices used in the medical procedure. The selection of the recommended action for controlling any of one or more of a first, second, third, and so forth endovascular device may be further based on the detected portion of any of the endovascular devices used in the medical procedure.
As shown in step 440, the method may include providing a set of instructions to perform the recommended action. The instructions may include an instruction configured to cause the control device to transform the endovascular device. Furthermore, the instruction may include an indication of a desired parameter of the control device. A desired parameter may include, for example, a desired curvature of the guide wire or guide catheter, a desired expanded or contracted state of the mesh segment of the stent retriever or of the adjustable mesh device, a desired location of the endovascular device, a desired amount of coil for an embolism, a desired temperature of the endovascular device during endovascular warming to treat hypothermia.
In some embodiments, the set of instructions may be provided to the user. For example, the set of instructions may be provided to the user via a user interface, such as the peripheral device 140 of
As shown in step 450, the method may include receiving and analyzing an additional medical image. The additional medical image may be captured after the set of instructions were provided. This may provide an evaluation of a particular action after the performance of said action.
As shown in step 460, in some embodiments, the method may include selecting an additional recommended action. The additional recommended action may be selected based on the analysis of the additional medical image. As shown in step 470, the method may include providing additional instructions to perform the additional recommended action. The additional instructions may be generated and provided by performing steps 410-440 using the additional medical image.
As shown in step 480, in other embodiments, the method may include assessing a performance of the recommended action. The assessment may be based on the analysis of the additional medical image. As shown in step 490, an additional set of instructions configured to perform the additional recommended action may be provided. The additional set of instructions may be generated and provided by performing steps 410-440 using the additional medical image, where the performance of the recommended action may be included in the analyzing 420 and selecting 430.
Further, in some embodiments, the assessing of the performance of an action 480 and the selecting of an additional action 460 may both be performed and additional instructions 470 and/or 490 may be provided based on the assessment 480 and selection 460.
As shown in step 510, the method may include receiving a medical image captured prior to or during an invasive procedure. The method may include analyzing the medical image to detect a body structure and/or a portion of an endovascular device in the body structure, as shown in step 520.
As shown in step 530, the method may include selecting a recommendation for a prospective course of action. The selection of the recommendation for a prospective course of action may be based on the detected body structure and/or a portion of the endovascular device in the body structure.
The recommendation for a prospective course of action may include a recommendation of a specific device to use, such as a catheter (e.g., aspiration catheter or guide catheter), a microcatheter, a stent retriever (e.g., a controllable stent retriever), a stent, an adjustable mesh device, a guide wire (e.g., a controllable guide wire), and/or other intraluminal or endovascular device, or of a specific size of the endovascular device to use. Additionally, or alternatively, the recommendation may include a location the endovascular device should be placed in the body structure (e.g., in reference to a clot or narrowing in a body structure, or in reference to an aneurysm). The recommendation may also include a rotational angle and location in which bending should be implemented to advance through tortuous anatomy. Furthermore, the recommendation may include a size to open the mesh to integrate a clot and a size to close, or contract, the mesh to remove the clot. Additionally, or alternatively, the recommendation may be a particular retrieval speed and/or retrieval force.
Furthermore, as shown in step 540, the method may include providing the recommendation to a user performing the invasive procedure.
As shown in step 610, the method may include receiving a medical image captured prior to or during an invasive procedure. The method may include analyzing the medical image to detect a body structure and/or a portion of an endovascular device in the body structure, as shown in step 620. A body structure size, body structure diameter, a type of body structure narrowing, an extent of body structure narrowing, a clot size, and/or a clot type may be determined based on the detected body structure and/or portion of the endovascular device.
As shown in step 630, the method may include selecting an action for controlling the endovascular device during the invasive procedure. The selection may be based on the detected body structure and/or the portion of the endovascular device in the body structure. In some embodiments, the selected action may be an expansion or contraction of a distal portion of the endovascular device. In other embodiments, the selected action may be a change in a speed of pushing or speed of pulling of the endovascular device. The selected action may include a change in frequency of the expansion or contraction of a distal portion of the endovascular device. The selected action may also include an activation of an aspiration catheter. Furthermore, the selected action may include a bending of at least one distal portion of the endovascular device. As shown in step 640, the method may include causing the performance of the selected action.
Performance of the selected action may include instructions configured to control the endovascular device, where the instructions include one or more parameters associated with the selected action. For example, the selected action may include a bending of a distal portion of the endovascular device. The instructions may include parameters indicating the desired bending curvature and speed of bending. The endovascular device may perform the selected action in accordance with the one or more parameters included in the instructions.
Additional embodiments of method of automation of an endovascular procedure may include or involve any of the above-mentioned steps illustrates in
In some embodiments, an automation may include a user providing information for performing an action or procedure and the action or procedure proceeding automatically (i.e., without user intervention). Examples of procedures may include, but are not limited to, clot retrieval, dilation of narrowed body structures (e.g., blood vessels), vessel remodeling for support of embolism for treatment of aneurysm, and endovascular coiling for treating aneurysms. In some embodiments, an automation may include parts of the medical procedure discussed above, such as but not limited to, moving the endovascular device forward (e.g., to a desired site within the body of a patient); retracting the endovascular device out of the body structure (e.g., at a constant force and/or speed); expanding or collapsing a mesh segment of the endovascular device to a desired diameter; exerting a pulsatile motion, such as but not limited to, expansion and contraction of a mesh segment for integration of a clot; activating suction in an aspiration catheter; and/or causing a bend in at least one distal portion of a guide wire or a guide catheter.
According to some embodiments, a user may mark a treatment site on or based on a medical image and the endovascular device may navigate to the treatment site, where the endovascular device is controlled by a control device, such as control device 110. The user may designate a type of procedure required and the endovascular device, controlled by a control device such as control device 110, may automatically navigate to a site of treatment. Furthermore, in some embodiments, the procedure may be performed automatically by the endovascular device, controlled by a control device such as control device 110, after a designated treatment site and/or type of procedure is indicated or required.
In some embodiments, a user may designate specific parameters such as the size of a clot, diameter of a body structure (e.g., a blood vessel), extent of a mesh expansion required, length of time required to integrate a clot by pulsatile motion, size of an aneurysm, and/or other indicators of the state of the body structure and/or endovascular device. The endovascular device, controlled by the control device, may then carry out a procedure, where the procedure uses the designated specific parameters in guiding the procedure.
Furthermore, in other embodiments, the user may perform a procedure in the body of a patient. The automation may then perform the retrieval of the device from the body of the patient at a constant speed and force.
