Abstract

Devices, systems and methods for passing a suture. In general, described herein are suturing devices, such as suture passers, as well as methods of suturing tissue. These suture passing devices are dual deployment suture passers in which a first distal jaw member is moveable at an angle with respect to the longitudinal axis of the elongate body of the device and the second distal jaw member is retractable proximally to the distal end region of the elongate body and/or the first jaw member. Methods of suturing tissue using a dual deployment suture passer are also described.

Claims

1. A suture passer device comprising:

an elongate body having a proximal end region and a distal end region;

a first jaw member extending from the distal end region of the elongate body and configured for angular movement relative to the elongate body;

a second jaw member configured to extend axially relative to the elongate body, the second jaw configured to form an opening with the first jaw member when the second jaw member is axially extended, wherein the second jaw member is configured to move independently of the first jaw member; and

a tissue penetrator deployably held within either the first or second jaw member and configured to pass a suture between the first and second jaw members by extending and retracting between the first and second jaw members when the first and second jaw members form the opening.

2. The device of claim 1, wherein the tissue penetrator is configured to extend and retract between the first and second jaw members without extending substantially beyond a lateral side of the first or second jaw members opposite the opening.

3. The device of claim 1, wherein the second jaw member is configured to move axially by extending distally or retracting proximally from the distal end region of the elongate body.

4. The device of claim 1, wherein the opening formed by extending the second jaw member comprises a distal-facing opening.

5. The device of claim 1, further comprising a suture engagement region near a distal tip of the tissue penetrator, the suture engagement region configured to couple with a suture.

6. The device of claim 1, further comprising a travel limiter configured to prevent the tissue penetrator from extending substantially beyond a lateral side of the first or second jaw members opposite the opening.

7. The device of claim 1, further comprising a movement limiter configured to limit the movement of the tissue penetrator based on a position of the first jaw member, the second jaw member or both the first and second jaw members, relative to the elongate body.

8. The device of claim 1, further comprising a second jaw holdfast configured to hold the second jaw member in an axial position relative to the elongate body.

9. The device of claim 1, further comprising a first jaw holdfast configured to hold the first jaw member in an angular position relative to the elongate body.

10. The device of claim 1, further comprising a first control for controlling the angular position of the first jaw member relative to the elongate body and a second control for controlling the axial position of the second jaw member relative to the elongate body.

11. The device of claim 1, further comprising an indicator for indicating when the second jaw is in a predetermined axially extended position relative to the elongate body.

12. The device of claim 1, further comprising a proximal handle having controls for controlling at least one of the angular movement of the first jaw member, the axial movement of the second jaw member or the extension and retraction of the tissue penetrator.

13. The device of claim 1, wherein the tissue penetrator is housed and extends from within the second jaw member.

31. The device of claim 1, wherein the opening between the first and second jaws is an angular opening.

32. The device of claim 1, wherein the second jaw member is configured to retract into the distal end region of the elongate body.

33. The device of claim 1, wherein the second jaw member is configured to retract into the distal end region of the elongate body so that most or all of the second jaw member is held proximal to the distal end of the elongate body.

14. A suture passer device comprising:

an elongate body having a proximal end region and a distal end region;

a first jaw member extending from the distal end region of the elongate body and configured for angular movement relative to the elongate body;

a second jaw member configured to extend distally or retract proximally from within the distal end region of the elongate body; and

a tissue penetrator configured to pass a suture between the first and second jaws and further configured to extend and retract between the first and second jaw members when the second jaw member is extended distally to form a distal-facing opening with the first jaw member.

15. The device of claim 14, further comprising a suture engagement region near a distal tip of the tissue penetrator, the suture engagement region configured to couple with a suture.

16. The device of claim 14, further comprising a movement limiter configured to limit the movement of the tissue penetrator based on a position of the first jaw member, the second jaw member or both the first and second jaw members.

17. The device of claim 14, further comprising a second jaw holdfast configured to hold the second jaw member in an axial position relative to the elongate body.

18. The device of claim 14, further comprising a first jaw holdfast configured to hold the first jaw member in an angular position relative to the elongate body.

19. The device of claim 14, further comprising a first control for controlling the angular position of the first jaw member relative to the elongate body and a second control for controlling the axial position of the second jaw member relative to the elongate body.

20. The device of claim 14, further comprising a travel limiter preventing the tissue penetrator from extending beyond a lateral side of the first or second jaw members opposite the distal-facing opening.

21. The device of claim 14, further comprising a proximal handle having controls for controlling at least one of the angular movement of the first jaw member, the axial movement of the second jaw member and the extension and retraction of the tissue penetrator.

22. The device of claim 14, wherein the tissue penetrator is housed and extends from within the second jaw member.

34. The device of claim 14, wherein the second jaw member is configured to retract into the distal end region of the elongate body so that most or all of the second jaw member is held proximal to the distal end of the elongate body.

23. A suture passer device comprising:

a hinged first jaw member extending from a distal end of an elongate body and configured to controllably bend relative to a longitudinal axis of the elongate body;

an axially sliding second jaw member configured to extend distally and retract proximally relative to the distal end of the elongate body to form a distal-facing opening with the first jaw member when the second jaw member is extended distally;

a tissue penetrator housed within the second jaw member and configured to extend across the distal-facing opening to the first jaw member;

a suture engagement region disposed near a distal end of the tissue penetrator and configured to engage a suture; and

a travel limiter configured to engage the tissue penetrator and prevent the tissue penetrator from extending beyond a lateral side of the first or second jaw members opposite the distal-facing opening.
