CATHETER DESIGN TOOL AND METHODS THEREOF

SUMMARY

The techniques of the present disclosure generally relate to a tool that can be used to select and/or design one or more catheter profiles for a particular individual or group of individuals. For example, catheter profiles may be designed to quickly serve a patient population of interest by incorporating realistic anatomic measurements, enforcing heuristics for a particular catheter design (e.g., stiff sections for a first length, compliant sections for a second length, etc.), and providing data regarding successful catheter paths within an anatomy. Also, for example, the utility of an existing catheter design may be estimated in a new population based on provided anatomic data from that population. Specifically, an existing catheter profile may be selected for a particular patient or patient population using, for example, preoperative imaging or anatomic correlation with a specific demographic (e.g., patient height, body mass index (BMI), weight, ethnicity, gender, disease state, etc.).

The tool may operate in a variety of different ways to select or design one or more optimal catheter profiles for a patient or group of patients. For example, the tool may gather a data set including, e.g., anatomy/catheter design bounds, compute valid catheter paths, and obtain new/optimized catheter shape parameters that would drive implant success in a particular population (e.g., having those anatomy design bounds). Specifically, in application, the tool may include preoperative/perioperative decision making, backwards-looking judgments about how current catheter profiles have performed in the past, intraoperative guidance, and optimizing future catheter designs. In one or more embodiments, the tool may include determining one or more optimal catheter profiles from a plurality of catheter profiles based on a plurality of anatomy parameters and a plurality of catheter parameters. Also, in one or more embodiments, the tool may include evaluating a catheter profile in view of a plurality of anatomy parameters and a plurality of catheter parameters. Further, in one or more embodiments, the tool may include determining guidance for navigating a catheter profile within an anatomy based on a plurality of anatomy parameters and a plurality of catheter parameters. Further yet, in one or more embodiments, the tool may include designing one or more optimal catheter profiles based on a catheter path having a plurality of anatomy parameters.

The details of one or more aspects of the disclosure are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the techniques described in this disclosure will be apparent from the description and drawings, and from the claims.

DETAILED DESCRIPTION

The present disclosure generally provides a catheter design tool or system and methods thereof for selecting or designing an optimal catheter profile for a particular patient or group of patients. For example, the tool or system may include a data set (e.g., input into the system) pertaining to a plurality of anatomy parameters and a plurality of catheter parameters to determine one or more catheter profiles that allow the best implant efficacy for a particular patient or group of patients. Specifically, the tool may evaluate the efficacy of a particular catheter profile for use with a particular patient, the most optimal catheter profile from a plurality of catheter profiles for use with a particular patient, and/or the most optimal catheter profile from a plurality of catheter profiles for use with a group of patients (e.g., divided by anatomic measurements or anatomic correlation with demographics). In other words, the tool may increase efficiency by selecting or designing the most effective catheter profile for a particular anatomy and eliminating potential waste created by using multiple catheter profiles to find the “best” catheter profile. It is noted that the term “catheter profile” as described herein may include a physical catheter (and the features thereof) or a representation of a catheter (and the features thereof).

Additionally, the data set (particularly the plurality of anatomy parameters) may be used to determine an optimal catheter path within one or more anatomies such that an optimal catheter profile may be designed having a plurality of catheter parameters. For example, the optimal catheter profile may be designed to be suitable for a particular anatomy or for a majority of anatomies (e.g., within a group). Furthermore, the tool may be used to provide guidance for navigating a catheter profile within an anatomy based on the data set.

As used herein, the term “or” refers to an inclusive definition, for example, to mean “and/or” unless its context of usage clearly dictates otherwise. The term “and/or” refers to one or all of the listed elements or a combination of at least two of the listed elements.

As used herein, the phrases “at least one of” and “one or more of” followed by a list of elements refers to one or more of any of the elements listed or any combination of one or more of the elements listed.

All scientific and technical terms used herein have meanings commonly used in the art unless otherwise specified. The definitions provided herein are to facilitate understanding of certain terms used frequently herein and are not meant to limit the scope of the present disclosure.

However, it will be understood that other aspects not depicted in the drawings fall within the scope of this disclosure. Like numbers used in the figures refer to like components, steps, and the like. However, it will be understood that the use of a reference character to refer to an element in a given figure is not intended to limit the element in another figure labeled with the same reference character. In addition, the use of different reference characters to refer to elements in different figures is not intended to indicate that the differently referenced elements cannot be the same or similar.

FIG. 1 shows a process 100 of determining one or more optimal catheter profiles from a plurality of catheter profiles based on a plurality of catheter parameters of the plurality of catheter profiles and a plurality of anatomy parameters. For example, there may be various instances in which a most optimal catheter profile is selected for an individual person (e.g., having a specific anatomy) or a group of people (e.g., having various anatomies).

Specifically, this information may be useful in settings including, e.g., in a clinic or operating room when treating a single patient, when determining which catheter profile functions most optimally for a specific group of people, when presented with a collection of various catheter profiles and determining which functions most optimally, when ranking a collection of various catheter profiles for one person or multiple people, etc.

The process 100 may include receiving 110 a plurality of anatomy parameters related to one or more anatomies. In other words, specific parameters or characteristics of a patient's anatomy may be input into a tool (e.g., through a system or controller) in order to evaluate the catheter profile. The plurality of anatomy parameters may include venous or arterial boundary shapes and distances, locations of anatomic targets relative to other anatomic landmarks, atrial wall locations, valve structure, coronary sinus ostia, coronary artery takeoffs, ventricular free and septal wall locations, orientation, endocardial shape (e.g., concave, convex), etc.

The plurality of anatomy parameters may be derived in a variety of different ways. For example, the one or more anatomies may be imaged to determine the plurality of anatomy parameters. Specifically, the imaging may include magnetic resonance imaging (MRI), fluoroscopy, cineradiography, biplane fluoroscopy, biplane cineradiography, computed tomography (CT), intraoperative 2D/3D imaging system (O-Arm), ultrasound (US), a transesophageal echocardiography (TEE), intra-cardiac echocardiography (ICE), transthoracic echocardiography (TTE), intravascular ultrasound (IVUS), electromechanical wave imaging (EWI), neuro-endoscopy, single photon emission computed tomography (SPECT), magnetic resonance angiography (MRA), computed tomography angiography (CTA), positron emission tomography (PET), optical coherence tomography (OCT), optical imaging spectroscopy (OIS), a magnetic resonance spectroscopy (MRS), dynamic susceptibility contrast (DSC) MRI, a fluid-attenuated inversion recovery (FLAIR), rotational angiography, infrared (IR) imaging, ultraviolet (UV) imaging, and/or the like. Also, the one or more anatomies may be measured in any suitable way such as, e.g., by segmenting anatomic boundaries from volumetric images (e.g., to extract anatomic boundaries) or by computing a best-fit volume from two or more perspective images of an anatomy. In one or more embodiments, 2D images (e.g., ultrasound planes) of the one or more anatomies may be measured by identifying (e.g., either manually or automatically) landmarks important to the performance of the catheter profile. Further, a user may manually input the plurality of anatomy parameters into a system or controller of the tool (e.g., due to known values of the plurality of anatomy parameters).

Additionally, in one or more embodiments, the plurality of anatomy parameters may be provided through a database of biometric information. The plurality of anatomy parameters may be selected and input as desired by a user to represent the one or more anatomies. For example, the one or more anatomies may correlate to a demographic group. Further, in one or more embodiments, the one or more anatomies may be grouped into a plurality of demographic groups. Specifically, the demographic group may be identified within one or more of, e.g., height, body mass index (BMI), ethnicity, gender, disease state, etc. In other words, there may be some correlation between one or more anatomy parameters of the plurality of anatomy parameters when the one or more anatomies are grouped by demographic group. Therefore, the demographic group may be used to approximate one or more anatomy parameters to determine one or more optimal catheter profiles for the anatomies of the demographic group, as will be discussed further herein.

The process 100 may also include defining 120 a plurality of catheter profiles (e.g., providing a plurality of catheters, establishing a plurality of available catheter profiles, etc.). In some embodiments, the plurality of catheter profiles may draw from all different types of existing catheter profiles that are manufactured. In other embodiments, the plurality of catheter profiles may be a subset of catheter profiles (e.g., the catheter profiles that are presently available to a user). Further, the catheter profile may include a cardiac or neurostimulation lead delivery catheter (e.g., an electric or pacing lead), a peripheral catheter (e.g., balloon or stent delivery systems), a miniaturized leadless pacemaker delivery catheter, a catheter for advancing a guidewire, and/or a delivery catheter (e.g., to deliver drugs or medication).

Each catheter of the plurality of catheter profiles may include a plurality of catheter parameters. For example, each of the catheter profiles may differ based on a variety of different parameters or characteristics. Specifically, the plurality of catheter parameters of the plurality of catheter profiles may define shapes (e.g., arclengths, curvatures), stiffness, compliance, lengths (e.g., of various stiffness or compliance), wall thickness, diameter, etc.

Also, the process 100 may include generating 130 a catheter path for each of the plurality of catheter profiles within the one or more anatomies. As shown in FIG. 2, generating the catheter path for each of the plurality of catheter profiles may include simulating the anatomy 150 and the catheter path 160 for each of the catheter profiles extending therethrough. For example, the anatomy 150 may be segmented based on portions that interact with the catheter profile and specific catheter anatomy contact points and implant targets may be measured. Further, the pre-shaped catheter paths 160 for each of the plurality of catheter profiles may be imported into the segmented anatomy, e.g., as shown in FIG. 2. These catheter paths may represent a variety of different catheter parameters or pre-shapes (e.g., rigid or compliant catheter sections). The catheter paths for each catheter profile may enforce shape and stiffness restrictions to ensure compatibility with anatomy. Thereafter, catheter paths that collide with the anatomy may be eliminated or considered incompatible, leaving the catheter paths that are possible. In one or more embodiments, the process may be repeated with multiple anatomies such that catheter paths may be generated for each anatomy of multiple anatomies.

Additionally, the process 100 may include determining 140 one or more optimal catheter profiles from a plurality of catheter profiles, as shown in FIG. 1. It is noted that the term “optimal” may refer to one or more catheter profiles that are best suited for a particular procedure or application or better suited than the remaining catheter profiles. Further, for example, optimal may be defined by a clinical outcome, which may be determined by the catheter profile's ability to deliver therapy in the correct location and in the correct trajectory. Further yet, for example, a good metric for catheter efficacy or determining an optimal catheter profile may be defined by procedure time (e.g., shorter procedure times may equal less radiation, less opportunity for infection, and/or more efficient operation room scheduling). Thereafter, in one or more embodiments, the optimized catheter profiles or shapes (e.g., including arclengths and curvatures) may be reported or displayed. In one or more embodiments, the optimized catheter profiles may be reported or displayed by, for example, computer display, IP sheet or matrix, using parameters to drive the user (e.g., the selector) into certain catheter profiles. In some embodiments, a computer decision tree may assist in potential catheter profile matches based on what you want to do. Ultimately, the various catheter profiles may be auto mapped for a specific anatomy based on success rate or performance.

In one or more embodiments, the process may include digital manipulation of a catheter profile of the plurality of catheter profiles in a computer heart model based on geometric boundary conditions (e.g., the plurality of anatomy parameters). For example, the orientation of the superior vena cava (SVC), location of the coronary sinus (CS) ostium, and angle of the CS body to the right atrium may assist in guiding the user through a series of virtual procedure steps aimed at getting and engaging the catheter profile with the CS. Once the location of the catheter tip is as close to the CS ostium as can be based on the geometric constraints of the anatomy and baseline shape of the catheter profile, the alignment of the catheter tip to the body of the CS may be the final indicator of how well or poorly the catheter profile may align with and engage the CS. Catheter profile designs that are closer to the CS ostium (e.g., across the patient population) and aligned well with the CS body after manipulation (e.g., across the patient population) may be deemed to be the best design (e.g., optimal) for that population

In one or more embodiments, the one or more optimal catheter profiles may include a single catheter profile that best suits the one or more anatomies. In other embodiments, the one or more optimal catheter profiles may include multiple catheter profiles that equally suit the one or more anatomies (e.g., essentially equivalents). For example, the one or more optimal catheter profiles may pass a specified threshold upon which the catheter profile is determined to be “optimal.” The different types of threshold may include proximity to target or implant locations, the orientation of the catheter tip relative to a target, fit within the anatomy of interest (e.g., knowing whether the catheter profile is too big or too small for its intended purpose before the catheter is inserted into the patient), etc. In one or more embodiments, the one or more optimal catheter profiles may include at least one of the one or more optimal catheter profiles that may be ranked or grouped into tiers. Further, the one or more optimal catheter profiles may be identified with various advantages or disadvantages relative to one another.

Depending on the application, generating a catheter path and determining one or more optimal catheter profiles may take several forms. For example, in one or more embodiments, determining the one or more optimal catheter profiles may include eliminating that catheter profiles that are not applicable to or compatible with the one or more anatomies (e.g., leaving the catheter profiles that perform the intended function). In other words, the catheter profiles of the plurality of catheter profiles for which the catheter path collides with portions of the one or more anatomy may be eliminated. As such, the one or more optimal catheter profiles may simply be a collection of catheter profiles that were not eliminated from the plurality of catheter profiles (e.g., ones that are compatible).

In one or more embodiments, determining the one or more optimal catheter profiles from the plurality of catheter profiles may include determining the one or more optimal catheter profiles for a demographic group (e.g., from a plurality of demographic groups). For example, the demographic group may be strongly associated with one or more anatomy parameters that specifically fit one or more catheter profiles of the plurality of catheter profiles. In other words, the one or more optimal catheter profiles may be identified for a specific demographic group.

In some embodiments, it may be valuable for the catheter profile to interact with different portions of the anatomy. For example, determining the one or more optimal catheter profiles from the plurality of catheter profiles may include identifying locations within the one or more anatomies (e.g., based on the plurality of anatomy parameters) and comparing the plurality of catheter profiles to desired locations within the one or more anatomies. Specifically, in one or more embodiments, the catheter profile may contact the right ventricular outflow tract in a direction perpendicular to the septal wall in order to deliver a (e.g., miniaturized) leadless pacemaker, or the catheter profile may contact the CS ostium in a direction allowing cannulation in order to deliver a left heart lead, or the catheter profile may contact the atrial septum in order to puncture into the bundle of His, High or Mid septal wall (e.g., for LBBAP), etc. Also, in one or more embodiments, the catheter profile may extend within the pulmonary artery branch or branches to deliver a device/sensor into the branch or branches, or the catheter profile may extend within the lung airways (e.g., bronchioles) to excise tissue/biopsy, or the catheter profile may extend through coronary arteries for stent delivery, or the catheter profile may extend through the pulmonary veins for pulmonary vein isolation (e.g., ablation) and for cryo-therapy.

Further, in one or more embodiments, the identified locations may be used in Mitral valve repair (e.g., where catheters may be used to cross an existing valve or navigate through an existing valve frame) for structure heart cases. In one or more embodiments, for example, the catheter profile may travel along a contralateral approach in peripheral stenting of the legs (e.g., approach is in one leg, goes up and over through the abdomen, and back down the other leg). Therefore, in one or more embodiments, the process may include evaluating a position of each catheter profile within the anatomy (e.g., to determine whether the catheter profile may properly interact with a portion of the anatomy as desired).

FIG. 3 illustrates a method 200 of evaluating a catheter profile in view of an anatomy having a plurality of anatomy parameters. For example, in one or more embodiments, a user may only have access to a single catheter profile having a set of parameters or characteristics. As described herein, the catheter profile may be evaluated (e.g., how well does the catheter profile work) as it pertains to the efficacy (e.g., for implantation, stimulation, therapy (e.g., drug, biologic, or electrical) delivery, fixation, etc.) for a specific anatomy.

The method 200 may include receiving 210 a plurality of anatomy parameters related to an anatomy. In other words, specific parameters or characteristics of a patient's anatomy may be input into a tool (e.g., through a system or controller) in order to evaluate the catheter profile. The plurality of anatomy parameters may include venous or arterial boundary shapes and distances, locations of anatomic targets relative to other anatomic landmarks, atrial wall locations, valve structure, coronary sinus ostia, coronary artery takeoffs, ventricular free and septal wall locations, orientation, endocardial shape (e.g., concave, convex), etc.

The plurality of anatomy parameters may be derived in a variety of different ways. For example, the one or more anatomies may be imaged to determine the plurality of anatomy parameters. Specifically, the imaging may include magnetic resonance imaging (MRI), fluoroscopy, cineradiography, biplane fluoroscopy, biplane cineradiography, computed tomography (CT), intraoperative 2D/3D imaging system (O-Arm), ultrasound (US), a transesophageal echocardiography (TEE), intra-cardiac echocardiography (ICE), transthoracic echocardiography (TTE), intravascular ultrasound (IVUS), electromechanical wave imaging (EWI), neuro-endoscopy, single photon emission computed tomography (SPECT), magnetic resonance angiography (MRA), computed tomography angiography (CTA), positron emission tomography (PET), optical coherence tomography (OCT), optical imaging spectroscopy (OIS), a magnetic resonance spectroscopy (MRS), dynamic susceptibility contrast (DSC) MRI, a fluid-attenuated inversion recovery (FLAIR), rotational angiography, infrared (IR) imaging, ultraviolet (UV) imaging, and/or the like. Also, the one or more anatomies may be measured in any suitable way such as, e.g., by segmenting anatomic boundaries from volumetric images (e.g., to extract anatomic boundaries) or by computing a best-fit volume from two or more perspective images of the anatomy. In one or more embodiments, 2D images (e.g., ultrasound planes) of the one or more anatomies may be measured by identifying (e.g., either manually or automatically) landmarks important to the performance of the catheter profile. Further, a user may manually input the plurality of anatomy parameters into a system or controller of the tool (e.g., due to known values of the plurality of anatomy parameters).

The method 200 may also include defining 220 a catheter profile having a plurality of catheter parameter profiles (e.g., providing a catheter, establishing a catheter profile, etc.). For example, the plurality of catheter parameters of the catheter profile may include shapes (e.g., arclengths, curvatures), stiffness, compliance, lengths (e.g., of various stiffness or compliance), wall thickness, diameter, etc. Further, the catheter profile may include a cardiac or neurostimulation lead delivery catheter (e.g., an electric or pacing lead), a peripheral catheter (e.g., balloon or stent delivery systems), a miniaturized leadless pacemaker delivery catheter, a catheter for advancing a guidewire, and/or a delivery catheter (e.g., to deliver drugs or medication).

Also, the method 200 may include evaluating 230 the catheter profile in view of the plurality of anatomy parameters. The catheter profile may be evaluated in view of the plurality of anatomy parameters in a variety of different ways. For example, evaluating the catheter profile by determining a position of the catheter profile relative to an implant and/or stimulation region. The plurality of anatomy parameters may be used to establish the location of the implant/stimulation region. In one or more embodiments, a particular portion of the catheter profile (e.g., a pacing lead, balloon, delivery port, etc.) may be evaluated to position the portion of the catheter profile relative to a location within the anatomy. For example, a location within the anatomy may be identified based on the plurality of anatomy parameters and the catheter profile may be compared to the locations within the anatomy. Also, for example, the catheter profile may be evaluated on whether or not the catheter profile is compatible with the anatomy.

In one or more embodiments, a demographic group may define the plurality of anatomy parameters. Therefore, a specific catheter profile may be evaluated in view of the demographic group representing the plurality of anatomy parameters. The demographic group may be identified within a variety of different categories. For example, the demographic group may be identified within one or more of height, BMI, ethnicity, gender, disease state, etc.

Additionally, the method 200 may include determining 240 a performance of the catheter profile. The performance of the catheter profile may be represented in a variety of different ways. For example, if evaluating the catheter profile by determining whether or not a catheter profile is compatible with the anatomy, the performance metric may be determined that the catheter profile is compatible or incompatible. Further, in one or more embodiments, the performance metric may be relayed to the physician by indicating the catheter profile is compatible or incompatible, by superimposing the catheter profile on the patient's anatomy and color-coding regions of the catheter profile that fall outside of or near the boundaries of the anatomy, by providing a list of catheter shapes that are compatible with the patient's anatomy, etc.

Also, for example, it is noted the potential great variation from anatomy to anatomy such that the performance of one catheter profile in one anatomy may not match the performance of the same catheter profile in another anatomy. For example, FIGS. 4A and 4B illustrate anatomic variation in the atrial superior vena cava (SVC)/inferior vena cava (IVC) junction between two different hearts. As such, the catheter profile may not be compatible with the heart illustrated in FIG. 4A and the catheter profile may be compatible with the heart illustrated in FIG. 4B. Further, for example, FIG. 4C illustrates a tool design (e.g., a catheter profile) for a human implant that does not fit the anatomy structure of an animal. This information allows the user to identify early on the expected performance of a given tool or catheter profile prior to further implementation or use.

FIG. 5 illustrates a method 300 of determining guidance for navigating a catheter profile within an anatomy. For example, it may be beneficial for a user to understand the best path for navigating a specific catheter profile within a particular anatomy. By customizing the navigation based on the specifics for an individualized procedure, the user may more effectively carry out the procedure.

The method 300 may include receiving 310 a plurality of anatomy parameters related to an anatomy. In other words, specific parameters or characteristics of a patient's anatomy may be input into a tool (e.g., through a system or controller) in order to provide guidance for the catheter profile. The plurality of anatomy parameters may include venous or arterial boundary shapes and distances, locations of anatomic targets relative to other anatomic landmarks, atrial wall locations, valve structure, coronary sinus ostia, coronary artery takeoffs, ventricular free and septal wall locations, orientation, endocardial shape (e.g., concave, convex), etc.

The plurality of anatomy parameters may be derived in a variety of different ways. For example, the one or more anatomies may be imaged to determine the plurality of anatomy parameters. Specifically, the imaging may include magnetic resonance imaging (MRI), fluoroscopy, cineradiography, biplane fluoroscopy, biplane cineradiography, computed tomography (CT), intraoperative 2D/3D imaging system (O-Arm), ultrasound (US), a transesophageal echocardiography (TEE), intra-cardiac echocardiography (ICE), transthoracic echocardiography (TTE), intravascular ultrasound (IVUS), electromechanical wave imaging (EWI), neuro-endoscopy, single photon emission computed tomography (SPECT), magnetic resonance angiography (MRA), computed tomography angiography (CTA), positron emission tomography (PET), optical coherence tomography (OCT), optical imaging spectroscopy (OIS), a magnetic resonance spectroscopy (MRS), dynamic susceptibility contrast (DSC) MRI, a fluid-attenuated inversion recovery (FLAIR), rotational angiography, infrared (IR) imaging, ultraviolet (UV) imaging, and/or the like. Also, the one or more anatomies may be measured in any suitable way such as, e.g., by segmenting anatomic boundaries from volumetric images (e.g., to extract anatomic boundaries) or by computing a best-fit volume from two or more perspective images of the anatomy. In one or more embodiments, 2D images (e.g., ultrasound planes) of the one or more anatomies may be measured by identifying (e.g., either manually or automatically) landmarks important to the performance of the catheter profile. Further, a user may manually input the plurality of anatomy parameters into a system or controller of the tool (e.g., due to known values of the plurality of anatomy parameters).

The method 300 may also include defining 320 a catheter profile having a plurality of catheter parameters (e.g., providing a catheter, establishing a catheter profile, etc.). For example, the plurality of catheter parameters of the catheter profile may include shapes (e.g., arclengths, curvatures), stiffness, compliance, lengths (e.g., of various stiffness or compliance), wall thickness, diameter, etc. Further, the catheter profile may include a cardiac or neurostimulation lead delivery catheter (e.g., an electric or pacing lead), a peripheral catheter (e.g., balloon or stent delivery systems), a miniaturized leadless pacemaker delivery catheter, a catheter for advancing a guidewire, and/or a delivery catheter (e.g., to deliver drugs or medication).

Also, the method 300 may include determining 330 guidance for navigating the catheter profile within the anatomy. In one or more embodiments, the guidance for navigating the catheter profile within the anatomy may include an optimized path within the anatomy. In one or more embodiments, the guidance may include evaluating a position of the catheter profile within the anatomy. For example, the guidance may include displaying an image of the catheter profile extending along an optimized path within the anatomy. The imaging may be in any suitable form including, e.g., magnetic resonance imaging (MRI), fluoroscopy, cineradiography, biplane fluoroscopy, biplane cineradiography, computed tomography (CT), intraoperative 2D/3D imaging system (O-Arm), ultrasound (US), a transesophageal echocardiography (TEE), intra-cardiac echocardiography (ICE), transthoracic echocardiography (TTE), intravascular ultrasound (IVUS), electromechanical wave imaging (EWI), neuro-endoscopy, single photon emission computed tomography (SPECT), magnetic resonance angiography (MRA), computed tomography angiography (CTA), positron emission tomography (PET), optical coherence tomography (OCT), optical imaging spectroscopy (OIS), a magnetic resonance spectroscopy (MRS), dynamic susceptibility contrast (DSC) MRI, a fluid-attenuated inversion recovery (FLAIR), rotational angiography, infrared (IR) imaging, ultraviolet (UV) imaging, and/or the like.

In one or more embodiments, the system may also include determining an optimal site into which the catheter profile may be introduced into the patient. For example, the plurality of catheter parameters and the plurality of anatomy parameters may be considered to determine which introduction site may be most efficient for a given procedure.

Further, in one or more embodiments, the location of the catheter profile may be superposed on top of a previously recorded heart image. The physician may then overlay that image on a real time imaging and “follow the lead” to the correct anatomic location.

In one or more embodiments, a demographic group may define the plurality of anatomy parameters. Therefore, guidance for a specific catheter profile may be output for inserting the catheter profile within the anatomy based on the demographic group. The demographic group may be identified within a variety of different categories. For example, the demographic group may be identified within one or more of height, BMI, ethnicity, gender, disease state, etc.

FIG. 6 illustrates a method 400 of determining or designing one or more optimal catheter profiles having a plurality of catheter parameters. For example, a catheter profile may be designed and manufactured to a particular specification of one person or multiple people (e.g., based on a plurality of anatomy parameters). In other words, in one or more embodiments, an optimal catheter profile can be designed according to a plurality of catheter parameters that is customized to that one person or multiple people. Further, in some embodiments, the optimal catheter profile may be manufactured in a short period of time (e.g., using additive manufacturing or 3D printing) to that set of catheter parameters. As such, a catheter profile could be designed and manufactured “on-demand” for that one person or multiple people. This may allow the user to design and manufacture an “optimal” catheter profile in a short amount of time such that the “optimal” catheter profile can be used almost immediately.

The method 400 may include receiving 410 a plurality of anatomy parameters related to one or more anatomies. In other words, specific parameters or characteristics of a patient's anatomy may be input into a tool (e.g., through a system or controller) in order to design the optimal catheter profile. The plurality of anatomy parameters may include venous or arterial boundary shapes and distances, locations of anatomic targets relative to other anatomic landmarks, atrial wall locations, valve structure, coronary sinus ostia, coronary artery takeoffs, ventricular free and septal wall locations, orientation, endocardial shape (e.g., concave, convex), etc.

The plurality of anatomy parameters may be derived in a variety of different ways. For example, the one or more anatomies may be imaged to determine the plurality of anatomy parameters. Specifically, the imaging may include magnetic resonance imaging (MRI), fluoroscopy, cineradiography, biplane fluoroscopy, biplane cineradiography, computed tomography (CT), intraoperative 2D/3D imaging system (O-Arm), ultrasound (US), a transesophageal echocardiography (TEE), intra-cardiac echocardiography (ICE), transthoracic echocardiography (TTE), intravascular ultrasound (IVUS), electromechanical wave imaging (EWI), neuro-endoscopy, single photon emission computed tomography (SPECT), magnetic resonance angiography (MRA), computed tomography angiography (CTA), positron emission tomography (PET), optical coherence tomography (OCT), optical imaging spectroscopy (OIS), a magnetic resonance spectroscopy (MRS), dynamic susceptibility contrast (DSC) MRI, a fluid-attenuated inversion recovery (FLAIR), rotational angiography, infrared (IR) imaging, ultraviolet (UV) imaging, and/or the like. Also, the one or more anatomies may be measured in any suitable way such as, e.g., by segmenting anatomic boundaries from volumetric images (e.g., to extract anatomic boundaries) or by computing a best-fit volume from two or more perspective images of the anatomy. In one or more embodiments, 2D images (e.g., ultrasound planes) of the one or more anatomies may be measured by identifying (e.g., either manually or automatically) landmarks important to the performance of the catheter profile. Further, a user may manually input the plurality of anatomy parameters into a tool (e.g., using a system or controller).

The method 400 may also include generating 420 a catheter path within the one or more anatomies. The catheter path may take into account the plurality of anatomy parameters to determine the optimal path for a specific application. In one or more embodiments, the catheter path may include points of interest (e.g., implant and/or stimulation points) within the one or more anatomies through which the catheter path should travel.

Also, the method 400 may include designing 430 one or more optimal catheter profiles according to the catheter path. Each optimal catheter profile having a plurality of catheter parameters. Based on the catheter path, the one or more optimal catheter profiles may be designed according to the corresponding plurality of catheter parameters.
