Description

TECHNICAL FIELD

This disclosure relates generally to medical devices and surgical procedures, and more particularly to medical devices and methods used to implant and attach bodily implants within a body of a patient.

BACKGROUND

Bodily implants, such as mesh implants, are sometimes placed within a body of a patient. For example, sometimes implants are placed within a body of a patient to provide support to portions of the body of the patient. Implants may be placed within a pelvic region of a patient to provide support to portions of the pelvic region of the patent.

In some procedures for placing implants within a body of a patient, an implant is anchored or secured to bodily tissue. In some cases, it is desirable to limit or to control the depth of penetration of the anchor or other device used to couple or attach the implant within the body of the patient. For example, in some sacral colpopexy procedures, an implant is coupled to an outer surface of a vaginal wall of a patient. It can be desirable to control or limit the depth of penetration of the anchor or other device used to couple the implant to the outer surface of the vaginal wall. For example, it can be desirable to prevent the anchor or other device use to couple or attach the implant from penetrating into the vagina (or otherwise penetrate completely through the vaginal wall).

Accordingly, there is a need for medical devices and methods that allow for effective and efficient implant placement. For example, there is a need for devices and methods that allow for or help control the depth of penetration of an anchoring mechanism used to couple or attach an implant within a body of a patient.

SUMMARY

In one embodiment, a medical device includes an elongate member configured to be at least partially disposed within a body of a patient. The elongate member has an outer surface. The outer surface of the elongate member has a first ridge and a second ridge.

In another embodiment, a medical device includes an elongate member and an expander. The expander defines a lumen and is slidably coupled to the elongate member. The expander has a proximal end portion and a distal end portion. The distal end portion of the expander has a tapered section.

In another embodiment, a method of placing an implant within a body of a patient includes inserting a manipulator within a vagina of a patient; disposing the implant adjacent a vaginal wall of the patient; moving a first portion of the manipulator with respect to a second portion of the manipulator to expand the vagina of the patient; and attaching the implant to the vaginal wall of the patient.

For example, in some embodiments, the manipulator 530 is configured to be inserted into the body of the patient and manipulate the bodily tissue so as to facilitate the securement of the bodily implant to the bodily tissue.

The manipulator 530 includes an elongate member 532. The elongate member 532 has a proximal end portion 536 and a distal end portion 538. The elongate member has an outer surface 534 and defines a longitudinal axis A.

In the illustrated embodiment, the outer surface 534 of the manipulator 530 includes undulations or otherwise has a non-smooth surface. Specifically, in the illustrated embodiment, the outer surface 534 of the manipulator 530 includes or defines a first ridge or bump 582 and a second ridge or bump 584. The first ridge or bump 582 and the second ridge or bump 584 are disposed at the distal end portion 538 of the manipulator 530. The first ridge or bump 582 and the second ridge or bump 584 extend along the outer surface 534 of the manipulator in directions that are parallel to the longitudinal axis A of the manipulator 530. In other embodiments, the ridges or bumps may extend in directions that are not parallel to the longitudinal axis of the manipulator 530. Also, in other embodiments, the ridges or bumps may extend the entire length of the manipulator.

The outer surface 534 of the manipulator 530 includes or defines troughs or indentations 592, 594, and 596. The troughs or indentations 592, 594, and 596 are disposed at the distal end portion 538 of the manipulator 530. The troughs or indentations 592, 594, and 596 extend in directions that are parallel to the longitudinal axis A of the manipulator 530. In the illustrated embodiment, the troughs or indentations 592, 594, and 596 are disposed adjacent the ridges or bumps 582 and 584. In other embodiments, the troughs or indentations may extend in directions that are not parallel to the longitudinal axis of the manipulator 530. Also, in other embodiments, the troughs or indentations may extend the entire length of the manipulator.

FIG. 14 is a cross-sectional view of the manipulator 530 taken along line B-B of FIG. 13 (line B-B extends perpendicular to the longitudinal axis A of the manipulator 530). As best illustrated in FIG. 14, the first ridge or bump 582 and the second ridge or bump 584 extend a distance from the longitudinal axis A that is greater than other portions of the outer surface 534 of the manipulator 530. For example, the ridges or bumps extend a distance from the longitudinal axis A that is greater than the distance that the troughs or indentations extend from the longitudinal axis A.

In the illustrated embodiment, the manipulator 530 is configured to be inserted into a vagina of the patient and to manipulate the vaginal tissue or vaginal walls of the patient. Specifically, the manipulator 530 may be inserted into the vagina of the patient such that distal end portion 538 is disposed within the vagina. The proximal end portion 536 may extend from the vagina and allow the physician to control the movement of the manipulator 530. As best illustrated in FIG. 15, the vaginal wall VW of the vagina of the patient conforms to the contour or outer surface 534 of the manipulator 530. Specifically, the vaginal wall VW extends over the ridges or bumps 582 and 584 and depress or fold into the troughs or indentations 592, 594, and 596.

In some cases, such manipulation of the vagina or the vaginal wall VW facilitates the placement of the implant in a correct location with respect the vagina and the securement of the implant to the vagina or tissue proximate the vagina via the anchor. For example, a delivery tool (such as a needle) or an anchor may be inserted into the vaginal wall VW along the line C of FIG. 15 to couple the anchor to the vaginal wall VW but not extend to the vaginal canal of the patient. In some embodiments, the manipulator 530 may be inserted into that vagina of the patient and the delivery tool (or anchor) may be inserted into the body via an abdominal incision.

For example, a vacuum source VS or sources may be operatively coupled to the lumens via the openings defined by the manipulator 730 near the proximal end of the manipulator 730. For example, a coupling device CO may operatively couple a vacuum source VS to the lumens.

In the illustrated embodiment, the manipulator 730 is configured to be inserted into a vagina of the patient and to manipulate the vaginal tissue or vaginal walls of the patient. Specifically, the manipulator 730 may be inserted into the vagina of the patient such that distal end portion is disposed within the vagina. The proximal end portion may extend from the vagina and allow the physician to control the movement of the manipulator 730. Once the manipulator 730 is in place within the vagina the vacuum source may be activated or turned on to create a vacuum through the lumens 711, 713, and 715. In some embodiments, the vacuum may facilitate the conforming of the vaginal wall to the outer surface of the manipulator 730. Once the procedure is completed, the vacuum source may be removed or turned off and the manipulator 730 may be removed from the body of the patient.

In some embodiments, the expander includes a handle portion disposed at or near the proximal end portion 862.

FIGS. 24-27 schematically illustrated a process or method for disposing an implant into a body of a patient according to an embodiment of the invention. Additionally, FIG. 28 is a flow chart that details the steps of the process or method 900. As illustrated in FIG. 24 (at 910 of FIG. 28), the manipulator 830 may be inserted into the body of the patient via the vagina V of the patient. The manipulator 830 may be inserted into the body while the manipulator 830 is in its retracted configuration or position (as shown in FIG. 22). As illustrated in FIG. 24, the implant 810 may also be inserted into the body of the patient. The implant 810 in some cases is inserted into the body via an abdominal incision.

As illustrated in FIG. 25 (at 920 of FIG. 28), the implant 810 may be positioned or fit over the vagina. For example, the vagina may be placed into the lumen 816 defined by the implant 810.

As illustrated in FIG. 26 (at 930 of FIG. 28), the expander 834 of the manipulator 830 may be moved or slid to its extended or expanded configuration (as illustrated in FIG. 23). The placement of the expander 834 within the vagina of the patent will cause the vagina to stretch or expand and will tension the implant 810 against the walls of the vagina. The implant 810 can then be secured to the vaginal walls. For example, in some embodiments, an anchor or coupling mechanism may be used to couple or secure the implant 810 to the vaginal walls. In some embodiments, the implant 810 may be coupled to the anterior vaginal wall (or tissue proximate or near the anterior vaginal wall) and may also be coupled to the posterior vaginal wall (or tissue proximate or near the posterior vaginal wall). In other embodiments, a suture or other coupling mechanism may be used. In some embodiments, the implant 810 is coupled to the vaginal walls via a laparoscopic procedure or an abdominal incision.

As illustrated in FIG. 27 (at 940 of FIG. 28), the expander 834 may be moved back to its refracted configuration (as illustrated in FIG. 22). In some embodiments, a portion of the expander 834 remains outside of the body of the patient to facilitate the grasping and moving of the expander 834. In some embodiments, the implant 810 is coupled to the sacrum or tissue proximate the sacrum. The attachment of the implant 810 to the sacrum may be done via an anchor, a suture, or any other coupling mechanism. Additionally, in some embodiments, the implant 810 is cut to remove excess portions of the implant 810. Also, in some embodiments, lateral edges of the implant 810 proximate the vagina of the patient may be cut.

The manipulator 830 may then be removed from the vagina of the patient.
