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 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. 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 method of suturing tissue, the method comprising:

placing a first jaw member of a suture passer on a first side of a target tissue and a second jaw member of the suture passer on a second side of the target tissue, wherein the first jaw member extends in a first axis and the second jaw member extends in a second axis to form a V-shaped, distal-facing mouth;

extending a tissue penetrator from the second jaw member so that a distal end of the tissue penetrator is deflected against a second deflection surface of the second jaw member as the tissue penetrator is extended from the second jaw member and across the V-shaped, distal-facing mouth; and

deflecting the tissue penetrator against a first defection surface of the first jaw member so that the distal end of the tissue penetrator is directed distally along the first axis of the first jaw member while the proximal end of the tissue penetrator remains in the second jaw member, forming a sigmoidal pathway.

2. The method of claim 1, wherein extending the tissue penetrator from the second jaw member comprises pushing a suture through the target tissue with the tissue penetrator as it is extended from the second jaw member and across the V-shaped, distal-facing mouth.

3. The method of claim 1, wherein placing the first jaw member comprises placing the first jaw member on the first side of a knee meniscus and the second jaw member on the second side of the knee meniscus.

4. The method of claim 1, further comprising retracting the tissue penetrator from the first jaw, across the V-shaped, distal-facing mouth and back in to the second jaw member so that the tissue penetrator extends along the second axis of the second jaw member.

5. A method of suturing tissue, the method comprising:

placing a first jaw member of a suture passer on a first side of a target tissue;

sliding a second jaw member axially from the suture passer so that it is on a second side of the target tissue, wherein the first jaw member extends in a first axis and the second jaw member extends in a second axis to form a V-shaped, distal-facing mouth;

extending a tissue penetrator from the second jaw member so that a distal end of the tissue penetrator is deflected against a second deflection surface of the second jaw member as the tissue penetrator is extended from the second jaw member and across the V-shaped, distal-facing mouth; and

deflecting the tissue penetrator against a first defection surface of the first jaw member so that the distal end of the tissue penetrator is directed distally along the first axis of the first jaw member, forming a sigmoidal pathway.

6. The method of claim 5, wherein the distal end of the tissue penetrator is directed along the first axis of the first jaw member while the proximal end of the tissue penetrator remains in the second jaw member in the second axis.

7. The method of claim 5, wherein extending the tissue penetrator from the second jaw member comprises pushing a suture through the target tissue with the tissue penetrator as it is extended from the second jaw member and across the V-shaped, distal-facing mouth.

8. The method of claim 5, wherein placing the first jaw member comprises placing the first jaw member on the first side of a meniscus of a knee and the second jaw member on the second side of the meniscus.

9. The method of claim 5, further comprising retracting the tissue penetrator back in to the second jaw member so that the tissue penetrator extends along the second axis of the second jaw member.

10. A method of suturing tissue, the method comprising:

placing a first jaw member of a suture passer on a first side of a target tissue, wherein placing comprises changing the angle between the first jaw member and an elongate body of the suture passer to which the first jaw member is pivotally attached;

sliding a second jaw member axially from the elongate body of the suture passer so that the second jaw member is on a second side of the target tissue, wherein the first jaw member extends in a first axis and the second jaw member extends in a second axis to form a V-shaped, distal-facing mouth;

extending a tissue penetrator from the second jaw member so that a distal end of the tissue penetrator is deflected against a second deflection surface of the second jaw member as the tissue penetrator is extended from the second jaw member and across the V-shaped, distal-facing mouth; and

deflecting the tissue penetrator against a first defection surface of the first jaw member so that the distal end of the tissue penetrator is directed distally along the first axis of the first jaw member, forming a sigmoidal pathway.

11. The method of claim 10, wherein the distal end of the tissue penetrator is directed along the first axis of the first jaw member while the proximal end of the tissue penetrator remains in the second jaw member in the second axis.

12. The method of claim 10, wherein extending the tissue penetrator from the second jaw member comprises pushing a suture through the target tissue with the tissue penetrator as it is extended from the second jaw member and across the V-shaped, distal-facing mouth.

13. The method of claim 10, wherein placing the first jaw member comprises placing the first jaw member on the first side of a meniscus of a knee and the second jaw member on the second side of the meniscus.

14. The method of claim 10, further comprising retracting the tissue penetrator back in to the second jaw member so that the tissue penetrator extends along the second axis of the second jaw member.
