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 may include dual deployment suture passers in which a first distal jaw member is movable 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. Also described herein are suture passers in which the tissue penetrator passing the suture travels in an approximately sigmoidal pathway, with the distal end of the tissue penetrator extending distally from one jaw of the device.

Claims

1. A suture passer device having a suture-passing tissue penetrator that is configured to travel in a sigmoidal pathway, the device comprising:

a first jaw member extending distally from an elongate body, wherein the first jaw member includes a deflection surface and a distal-facing opening;

a second jaw member slidably extendable distally from the elongate body, wherein the first jaw member and the second jaw member form a distal-facing mouth; and

a tissue penetrator extendable from the second jaw member to pass across the distal-facing mouth, into the first jaw member, deflect against the deflection surface and extend distally from the distal-facing opening of the first jaw member.

2. The device of claim 1, further comprising a suture stripper in the first jaw member configured to strip a suture from the tissue penetrator and retain the suture in the first jaw member.

3. The device of claim 1, further comprising a suture stripper in the first jaw member configured as a leaf spring element for stripping a suture from the tissue penetrator and retains the suture in the first jaw member.

4. The device of claim 1, wherein the first jaw member is pivotable relative to the distal end region of the elongate body.

5. The device of claim 1, wherein the second jaw member is slideable distally and proximally relative to the elongate body.

6. The device of claim 1, further comprising a proximal handle comprising a first control for controlling the angle of the first jaw member relative to the elongate body and a second control for controlling distal and proximal extension of the second jaw member.

7. The device of claim 1, wherein the tissue penetrator comprises a suture retainer region configured to hold a length of suture as the tissue penetrator extends between the first and second jaw members.

8. The device of claim 7, wherein the suture retainer region comprises a lateral cut-out region of the tissue penetrator.

9. The device of claim 1, wherein the tissue penetrator is configured to extend distally from the distal-facing opening of the tissue penetrator by more than about 1 mm.

10. A suture passer device having a suture-passing tissue penetrator that is configured to travel in a sigmoidal pathway, the device comprising:

a first jaw pivotally coupled to the distal end region of an elongate body, wherein the first jaw is configured to pivot relative to the elongate member, wherein the first jaw includes a distal-facing opening;

a deflection surface within the first jaw;

a second jaw slideably extendable distally from the elongate body, wherein the first jaw and the second jaw are configured to form a distal-facing mouth;

a tissue penetrator housed within the second jaw and configured to extend from the second jaw across the distal-facing mouth and into the first jaw, deflect against the deflection surface, and extend distally from the distal-facing opening in the first jaw; and

a suture retainer region on the tissue penetrator configured to retain a suture as the tissue penetrator is extended across the distal-facing mouth.

11. The device of claim 10, wherein pivoting motion of the first jaw is independent of sliding motion of the second jaw.

12. The device of claim 10, further comprising a suture stripper in the first jaw configured to strip a suture from the tissue penetrator and retain the suture in the first jaw.

13. The device of claim 10, further comprising a suture stripper in the first jaw comprising a leaf spring element configured to strip a suture from the tissue penetrator and retain the suture in the first jaw.

14. The device of claim 10, further comprising a proximal handle comprising a first control for controlling pivoting and angle of the first jaw member relative to the elongate body and a second control for controlling distal and proximal extension of the second jaw.

15. The device of claim 10, wherein the suture retainer region comprises a lateral cut-out region of the tissue penetrator.

16. The device of claim 10, wherein the tissue penetrator is configured to extend distally from the distal-facing opening of the tissue penetrator by more than about 1 mm.

17. A suture passer device having a suture-passing tissue penetrator that travels in a sigmoidal pathway having two deflections, the device comprising:

a first jaw member extending distally from an elongate body, wherein the first jaw member includes a deflection surface and a distal-facing opening;

a second jaw member axially moveable between a proximal position and a distal position relative to the elongate body, wherein the first jaw member and the second jaw member form a distal-facing mouth when the second jaw member is in the distal position; and

a tissue penetrator configured to extend from the second jaw member, across the distal-facing mouth, into the first jaw member, deflect against the deflection surface and extend distally from the distal-facing opening of the first jaw member.
