Suture passers and methods of passing suture
First Claim

1. A suture passer for forming a loop of suture around a target tissue, the suture passer comprising:
- an elongate body extending distally and proximally along a long axis;
a first jaw extending from a distal end region of the elongate body wherein the first jaw is bent or bendable at an angle relative to the long axis;
a second jaw configured to slide axially along the long axis distally and proximally relative to the elongate body, further wherein the first jaw and the second jaw form a distal-facing opening when the second jaw is extended distally and wherein the second jaw is retractable proximally so that it does not form the distal-facing opening with the first jaw;
a tissue penetrator configured to extend across the distal-facing opening between the first jaw and the second jaw to pass a suture there between; and
a plate having a keyhole capture region, wherein the keyhole capture region comprises a capture pathway including a channel extending through the plate and a release pathway, wherein the capture pathway is connected to the release pathway by at least one bend, further wherein the plate is coupled to the first jaw so that it may receive a suture from the tissue penetrator extending from the second jaw.

Abstract
Suture passer devices, including suture passers configured with an axially slideable jaw that includes a tissue-penetrating distal end region. Also described are suture passers including jaws housing tissue penetrating needles to pass suture that are substantially thin. Methods of using such devices to pass a suture through tissue are provided.

8. A method of passing a loop of suture around a target tissue, the method comprising:
-
placing a first jaw of a suture passer adjacent to a first side of a target tissue, wherein the first jaw extends from a distal end of an elongate body of the suture passer; extending a second jaw of a suture passer adjacent to a second side of the target tissue to form a distal-facing mouth with the first jaw, wherein the second jaw extends in a distal direction from the distal end of the elongate body of the suture passer; extending a tissue penetrator between the first and second jaws of the distal facing mouth while pushing a capture member connected to a suture with the tissue penetrator; retracting the tissue penetrator without the capture member or suture back between the first and second jaws of the distal facing mouth; repositioning the first and second jaws relative to the target tissue; extending the tissue penetrator between the first and second jaws of the distal facing mouth and capturing the capture member with the tissue penetrator; and retracting the tissue penetrator with the capture member back between the first and second jaws of the distal facing mouth. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A suture passer device for passing a suture, the device comprising:
-
an elongate body extending distally and proximally along a long axis; a first jaw extending from a distal end region of the elongate body wherein the first jaw is bendable at an angle relative to the long axis; a second jaw having a sharp, tissue penetrating distal tip, wherein the second jaw is configured to be manually slid axially along the long axis distally and proximally relative to the elongate body, further wherein the first jaw and the second jaw form a distal-facing opening when the second jaw is extended distally and wherein the second jaw is retractable proximally so that it does not form the distal-facing opening with the first jaw; a tissue penetrator configured to extend across the distal-facing opening between the first jaw and the second jaw to pass a suture there between; and a cam surface coupled to the second jaw and configured to move the second jaw axially in conjugate motion with bending of the first jaw member. - View Dependent Claims (16, 17)

18. A suture passer device for passing a suture and providing feedback to the user, the device comprising:
-
an elongate body extending distally and proximally along a long axis; a first jaw extending from a distal end region of the elongate body wherein the first jaw is bent or bendable at an angle relative to the long axis; a second jaw having a sharp, tissue penetrating distal tip, wherein the second jaw is configured to slide axially along the long axis distally and proximally relative to the elongate body, further wherein the first jaw and the second jaw form a distal-facing opening when the second jaw is extended distally and wherein the second jaw is retractable proximally so that it does not form the distal-facing opening with the first jaw; a tissue penetrator configured to extend across the distal-facing opening between the first jaw and the second jaw to pass a suture there between; and an audible feedback actuator configured to provide an audible signal when the tissue penetrator is fully extended across the distal-facing opening.
