In accordance with various embodiments, a probe may be inserted into a body cavity to perform diagnostic intervention(s), therapeutic intervention(s), or both. The probe may be inserted through a body aperture that is naturally occurring or man-made, intentionally or by accident. The body aperture may form a seal encircling the probe so that insufflation retention material may be effectively retained in the body cavity so that an operator can perform the intervention(s). However, there may be leakage of the insufflation material. The insufflation retention device is configured to form an effective seal contactingly adjacent the body aperture and to provide a passageway for the introduction of the probe into the body cavity.
There are technologies that allow operators to introduce a probe, e.g., a medical scope, into a body cavity for diagnostic intervention or therapeutic intervention or both. When the probe is introduced, the body cavity may need to be expanded for the operator to perform the intervention(s). Using an insufflation technique, the operator may introduce an insufflation material to expand the body cavity, so the operator may have more room to work and better visibility in the body cavity to perform the intervention(s). E.g., see Technology Status Evaluation Report: Methods of luminal distension for colonoscopy, Gastrointestinal Endoscopy, Volume 77, No. 4, 2013, pages 519-525, which is incorporated by reference in its entirety. The insufflation material may be air, carbon dioxide, water, or other suitable materials.
The operator may start with the probe outside a body, and the operator may advance the probe through tissue of the body to introduce the probe into a cavity of the body, i.e., the body cavity. The probe may be advanced through the tissue via an aperture of the body, i.e., the body aperture, that is a naturally occurring orifice, e.g., an anus, or a wound, e.g., a surgical incision or a traumatic injury. The body aperture may have elasticity that allows the body aperture to recover its size and shape after any deformation from the probe being advanced through the body aperture into the body cavity to effectively seal the outside of the body from the body cavity. Thereafter, the insufflation material introduced into the body cavity may be retained in the body cavity to help promote expansion of the body cavity when the outside of the body is effectively sealed from the body cavity to permit the operator to perform the intervention(s).
However, the insufflation material may not be effectively retained in the body cavity in some instances. For example, the body aperture or nearby structures may have a congenital malformation or may have suffered structural injury such as from scar tissue formation after abscess formation, surgical trauma, giving birth related injury, etc. that inhibits the body aperture from forming an effective seal with the probe.
If the insufflation material is not effectively retained, then the operator will not have time and room to work or visibility to operate in the body cavity. For example, the probe, such as an endoscope, may be introduced into the body cavity, such as a rectum and a large intestine, through the body aperture, such as the anus, and the elasticity of the body aperture may not effectively form a seal contactingly adjacent the probe to promote retention of the insufflation material in the body cavity. As will be described in further detail, this disclosure describes an insufflation retention device that promotes retention of the insufflation material in the body cavity.
As shown in
The internal buttress 108 may be configured to have an unexpanded configuration so that an operator may introduce the IRD 100 through the body aperture 106 into the body cavity 104. The unexpanded configuration of the internal buttress 108 may be smaller than an expanded configuration of the internal buttress 108 shown in
The expanded configuration of the internal buttress 108 is configured to prevent the IRD 100 from being removed from the body cavity 104. If the IRD 100 moved towards the exterior 118 of the body 102, then the expanded configuration of the internal buttress 108 would contactingly engage the body cavity 104 or the body aperture 106 or both to prevent the IRD 100 from being removed from the body cavity 104. In other words, in the expanded state the internal buttress 108 may be configured to inhibit removal of the internal buttress 108 from the body cavity 104 through the body aperture 106.
The internal buttress 108 in an unexpanded configuration or contracted state may be increased in size to the expanded configuration or state through introduction of an expansion material into an internal cavity of the internal buttress 108 supplied by a source. The expansion material may be broadly considered to be a fluid. Examples of the expansion material may be a liquid e.g., water, and a gas e.g., oxygen, air, compressed air, carbon dioxide, by way of example and not limitation.
The internal buttress 108 may be configured to form a body internal buttress seal 105 between the body cavity 104 and the internal buttress 108. The internal buttress 108 is shown generally as a doughnut shape; however, other shapes are contemplated depending on the need of the operator in view of the body 102 of a patient. The shape of the internal buttress 108 may be chosen to be a predetermined shape to effectively form the body internal buttress seal 105 between the body 102 and the internal buttress 108. Effectiveness of the body internal buttress seal 105 occurs when insufflation material is retained in the body cavity 104 so that the operator can perform the intervention(s) and the operator will have time and room to work or visibility to operate in the body cavity 104.
The external buttress 112 may be considered to have an unexpanded configuration or contracted state, also. However, the unexpanded configuration of the external buttress 112 is not required. The reason that the unexpanded configuration of the external buttress 112 is not required is that the external buttress 112 is configured to prevent the IRD 100 from being introduced into the body cavity 104. For example, the external buttress 112 may have the unexpanded configuration that is not configured to prevent introduction of the IRD 100 into the body cavity 104. In this example, a user or operator could then transform or transition the unexpanded configuration of the external buttress 112 into the expanded configuration of the external buttress 112 to prevent the IRD 100 from being introduced into the body cavity 104. In other words, the external buttress 112 may be configured to inhibit advancement of the external buttress 112 through the body aperture 106 into the body cavity 104.
As with the internal buttress 108, the external buttress 112 in an unexpanded configuration may be increased in size to the expanded configuration or state through introduction of an expansion material into an internal cavity of the external buttress 112 supplied by a source. The expansion material may again be broadly considered to be a fluid. The expansion material used to expand the internal buttress 108 and the external buttress 112 may be the same or different in any given situation.
However, the external buttress 112 need not have a smaller or unexpanded configuration, because the external buttress 112 does not need to be introduced through the body aperture 106. Therefore, the external buttress 112 may be of a size and configuration that is substantially the same before and after introduction of the IRD 100 into the body 102, and the external buttress 112 may be of a size and configuration that is substantially the same before, during, and after use of the IRD 100 in the body 102. However, for other practical considerations, it may be convenient for the external buttress 112 to have a smaller unexpanded configuration. For example, the external buttress 112 in the unexpanded configuration may more easily fit into a medical kit or packaging.
The external buttress 112 may be configured to form a body external buttress seal 107 between the body 102 and the external buttress 112. The external buttress 112 is shown generally as a cone shape; however, other shapes are contemplated depending on the need of the operator in view of the body 102 of the patient. The shape of the external buttress 112 may be chosen to be a predetermined shape to effectively form the body external buttress seal 107 between the body 102 and the external buttress 112. Effectiveness of the body external buttress seal 107 occurs when insufflation material is retained in the body cavity 104 so that the operator can perform the intervention(s) and the operator will have time and room to work or visibility to operate in the body cavity 104.
The midportion 110 is configured to couple the internal buttress 108 to the external buttress 112. The midportion 110 is configured to contactingly engage a wall 120 of the body aperture 106.
The midportion may be configured to form a body midportion seal 109 between the body aperture 106 and the midportion 110. The midportion 110 is generally shown as a cylinder; however, other shapes are contemplated depending on the need of the operator in view of the body 102 of the patient. The shape of the midportion 110 may be chosen to be a predetermined shape to effectively form the body midportion seal 109 between the body 102 and the midportion 110. Effectiveness of the body midportion seal 109 occurs when insufflation material is retained in the body cavity 104 so that the operator can perform the intervention(s) and the operator will have time and room to work or visibility to operate in the body cavity 104.
The interior surface 146 of the midportion 110 may be considered a sleeve that encircles the probe when the midportion 110 is in use. As shown, the sleeve may be substantially circular and disposed symmetrically within the body 140 of the midportion 110. Alternatively, the sleeve may be disposed asymmetrically within the body 140 of the midportion 110.
The IRD 100 may be made of one or more biologically compatible materials. The biocompatible material may be a polymer, such as silicone or latex. The same polymer may be used for the internal buttress 108 and the external buttress 112 or different polymers may be used for the internal buttress 108 and the external buttress 112. The same polymer may be used for the midportion 110 as is used for the internal buttress 108 and the external buttress 112 or different polymers may be used for the midportion 110, the internal buttress 108, and the external buttress 112. The midportion 110 may be formed of one piece with the internal buttress 108 and the external buttress 112, or the midportion 110 may be formed of a different piece from the internal buttress 108 and the external buttress 112. The internal buttress 108 and the external buttress 112 may be formed of different pieces, also. If different pieces are used to the form the IRD 100, then laser welding, etc. may be used to the join the pieces.
The expansion material conduit 142 of the midportion 110 may take any shape.
In addition, the midportion 110 may have an external surface 190 that is not substantially flat. In other embodiments, the external surface 190 of the midportion 110 may be substantially flat. In this embodiment shown in
Besides going from a contracted or unexpanded state with less of the expansion material to the expanded state with more of the expansion material, the midportion 110 generally and the contour, as a specific example that is not limiting, may be substantially rigid. In an embodiment with the substantially rigid contour, the midportion 110 does not substantially deform during use of the IRD 100 from the orientation and configuration with respect to the IRD 100 before or after use of the IRD 100.
As shown in this embodiment, the first body component 200 and the second body component 202 may have substantially parallel walls that are configured to effectively form a sleeve that provides a passageway for the probe when the first body component 200 may be coupled to the second body component 202. In this embodiment, a first internal buttress component 207 and a second internal buttress component 209 may be supplied with the expansion material via different introductions of the expansion material. In other words, the first internal buttress component 207 and the second internal buttress component 209 may not be in fluid communication.
Similarly, a first external buttress component 211 and a second external buttress component 213 may be supplied with the expansion material via different introductions of the expansion material, because the first external buttress component 211 and the second external buttress component 213 may not be in fluid communication. In this embodiment with the first body component 200 and the second body component 202, it may not be convenient to have the buttress components in fluid communication. Of course, one or more of the various buttress components may be in fluid communication, which is not shown.
In configuration shown in
In addition, the internal buttress 108 may overlap the body portion 240 as shown to help form an effective seal for retention of the insufflation material. Alternatively, the internal buttress 108 may not overlap the internal buttress body portion 240, as not shown, and still achieve an effective seal for retention of the insufflation material. Similarly, the external buttress may overlap or not overlap an analogous external buttress body portion to form an effective seal for retention of the insufflation material, which is not shown.
The apparatus may include an internal buttress configured to inhibit removal of the internal buttress from a body cavity through a body aperture of a body. An external buttress may be coupled to the internal buttress. The external buttress may be configured to inhibit entry of the external buttress into the body cavity through the body aperture. A passageway may extend through the internal buttress and the external buttress that is configured for passage of a probe into contacting engagement with the body cavity. The internal buttress in an expanded state may be configured to inhibit removal of the internal buttress from the body cavity through the body aperture, and the internal buttress in an unexpanded state may be configured to promote entry of the internal buttress into the body cavity through the body aperture. Alternatively, the internal buttress may be expanded with insertion of an expansion material to inhibit removal of the internal buttress from the body cavity through the body aperture, and the internal buttress may be contracted with removal of the expansion material to facilitate removal of the internal buttress from the body cavity through the body aperture.
Of course, the IRD 100 can be used with the probe 250 in the body aperture 106 without the presence of the abnormality 256. However, when the IRD 100 is used with the probe 250 in the body aperture 106 with the abnormality 256, the IRD 100 is configured to promote retention of the insufflation material inserted into the body cavity 104 for a time effective for operator performance of the diagnostic intervention, the therapeutic intervention, or both that is better than retention of the insufflation material could be achieved using the probe 250 without the IRD 100. A probe passageway seal 260, the body midportion seal 109, the body internal buttress seal 105, and the body internal buttress seal 105 may be configured to cooperate with the probe 250 to promote retention of the insufflation material inserted into the body cavity 104 for a time effective for operator performance of the diagnostic intervention, the therapeutic intervention, or both. On the other hand, the passageway 264 may be open without the probe 250 present in the passageway, such that the insufflation material may not be not retained in the body cavity 104.
The IRD 100 can effectively form seals, the body midportion seal 109 between the midportion 110 and the wall 120 of the body aperture 106, the body external buttress seal 107 between the external buttress 112 and the wall 120 of the body aperture 106, and the body internal buttress seal 105 between the internal buttress 108 and the body cavity 104 or the body 102, even in the presence of the abnormality 256. As shown in
Further, the IRD 100 can effectively form the probe passageway seal 260 when the probe 250 is inserted in the IRD 100. A passageway 264 through the midportion 110 of the IRD 100 may be configured to form the probe passageway seal 260 between the probe 250 and the passageway 264. The passageway 264 extends past the first end 174 and past the second end 176 (see
In addition, the external surface 190 of the midportion 110 may be configured to provide a contour feature 266 to engage the abnormality 256 to provide an effective seal. Of course, the contour feature 266 may be a protrusion, indentation, or combination of both to engage the abnormality 256 to provide an effective seal. Further, the contour feature 266 may be formed from the external buttress 112 or both the midportion 110 and the external buttress 112. In addition, the internal buttress 108 may have a contour feature, as discussed previously shapes are contemplated depending on the need of the operator in view of the body 102 of a patient.
An internal bias member 290 with biasing tension cooperates with a biasing tension of the rest of the IRD 100 to keep the IRD 100 closed during operation. The internal bias member 290 may be substantially flush with an interior of the IRD 100, or the internal bias member 290 may be substantially not flush with the interior of the IRD 100. On the other hand, the IRD 100 shown may be opened to wraparound the probe 250 when the probe 250 is in the body aperture 106, the body cavity 104, or both, and then the IRD may be inserted into and through the body aperture 106. The internal bias member 290 is configured for one-handed or two-handed operation.
An entry port 298 in the external buttress 112 may be configured to have a diameter wider than a diameter of the passageway 264, wherein the diameters are substantially parallel to each other. By having the diameter of the entry port 298 wider than the diameter of the passageway 264, the operator will have a larger target for insertion of the probe 250 into the passageway 264 then if the diameter of the entry port 298 was substantially the same size as the diameter of the passageway 264. The diameter of the passageway 264 may be configured and sized to fit closely around a diameter of the probe 250, so that the probe passageway seal between the passageway and the probe can be more easily achieved, and wherein again these diameters are substantially parallel to each other. There may be an internal taper 296 in the external buttress 112 so that the diameter of the entry port 298 can taper down to the smaller diameter of the passageway 264. While the internal taper 296 is shown as substantially linear resulting in a conical structure in
This embodiment is shown as a solid structure, which the IRD 100 may be if the internal buttress 108 is of a compressible material (e.g., foam by way of example and limitation), such that the internal buttress 108 may be pushed through the body aperture 106 in the contracted state and then once inside the body cavity 104, the internal buttress 108 may expand into the expanded state. Of course, this similar structure, such as with the entry port 298 having the internal tapered 296, may be present in conjunction with features from the other embodiments that include the internal buttress 108 that is expandable by the expansion material.
The external compression member 302 may have an internal bias member 304 that in the rolled configuration is internal to an external bias member 306 of the external compression member 302 in the closed position shown in
While the external compression member 302 is shown external to the balloon that forms the internal buttress 108, the external buttress 112, and a portion of the midportion 110, it is fully contemplated that the external compression member 302 may be internal to the passageway structure 300.
Further, the O-ring type structure 280 along the sleeve may further aid in promoting the seal between the IRD 100, e.g., the midportion 110, and the probe 250. The O-ring type structure 280 may be fixed to the sleeve at a first O-ring end 282 and mobile at an opposing, second O-ring end 284. The O-ring type structure 280 may be one of a plurality of O-rings type structures 280. While the O-ring type structure 280 may be rigid, there may be benefit in having the O-ring type structure 280 be flexible such that the opposing, second O-ring end 284 is dragged internally towards the body cavity 104 when the probe 250 is advanced and the opposing, second O-ring end 284 is dragged externally away from the body cavity 104 when the probe 250 is retracted.
As shown throughout the disclosure in the various embodiments, the internal buttress 108 and the external buttress 112 in some embodiments are not configured to engage the probe 250 and therefore the internal buttress 108 and the external buttress 112 may not contribute to the seal between the IRD 100 and the probe 250. In other embodiments, the internal buttress 108 and the external buttress 112 are configured to engage the probe 250 and therefore the internal buttress 108 and the external buttress 112 may contribute to the seal between the IRD 100 and the probe 250. Whether the internal buttress 108 and the external buttress 112 engage the probe 250, the internal buttress 108 and the external buttress 112 may contribute to the seal between the IRD 100 and the body 102, such as the body cavity 104, the body aperture 106, and the wall 120 of the body aperture 106.
Of course, care is taken to optimize the contact of the internal buttress 108, the external buttress 112, and other portions of the IRD 100 with the body 102, the body cavity 104, and the body aperture 106, and other aspects of a patient to minimize the risk for pressure necrosis or other untoward side effects from using the IRD 100. This care may be implemented by having a predetermined volume for the expansion material, which will in turn establish a predetermined pressure that the internal buttress 108, the external buttress 112, etc. of the IRD 100 exerts on the body 102, the body cavity 104, the body aperture 106, etc.
A method of using the IRD 100 may comprise the following steps. At the first step, the IRD 100 is inserted through the body aperture 106 of the body 102 into the body cavity 104 of the body 102. At the second step, the insufflation material is injected into the body cavity 104. At the third step, a user uses a probe to perform a diagnostic intervention, a therapeutic intervention, or both a diagnostic intervention and a therapeutic intervention. Further steps are contemplated. For example, and not by way of limitation, the probe may be inserted through the body aperture 106 before, after, or in conjunction with the IRD being inserted through the body aperture 106.
It is to be understood that even though numerous characteristics and advantages of various embodiments of the present disclosure have been set forth in the foregoing description, together with details of the structure and function of various embodiments of the disclosure, this detailed description is illustrative only, and changes may be made in detail, especially in matters of structure and arrangements of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
