Abstract

A tissue closure system for closing vaginal tissue includes a tissue closure device having an end effector supporting one or more sutures securable to vaginal tissue. The one or more sutures may be separated from the end effector and tied to the vaginal tissue. The tissue closure system may include a tissue approximation device configured to apply negative pressure to vaginal tissue for approximating portions of the vaginal tissue together.

First claim

What is claimed is:

1. A vaginal tissue closure system, comprising:
a tissue approximation device defining a longitudinal axis and having a paddle, the paddle movable relative to the longitudinal axis and including a suction aperture defined therein, the suction aperture configured to apply negative pressure to vaginal tissue to maintain the tissue in close proximity to the paddle as the paddle moves relative to the longitudinal axis; and
a tissue closure device including an end effector, the end effector supporting at least one suture, the end effector actuatable to position the at least one suture in vaginal tissue, the at least one suture separable from the tissue closure device to enable the at least one suture to close an opening formed in vaginal tissue,
wherein the end effector of the tissue closure device includes a first jaw member and a second jaw member, the first and second jaw members positionable between open and closed positions to selectively grasp vaginal tissue.

2. The vaginal tissue closure system of claim 1 , wherein the tissue approximation device and the tissue closure device are coupled to a handle assembly, the handle assembly configured to selectively actuate the tissue approximation device and the tissue closure device.

3. The vaginal tissue closure system of claim 1 , further comprising a vacuum source in communication with the suction aperture and configured to generate the negative pressure applied by the suction aperture to vaginal tissue.

4. The vaginal tissue closure system of claim 1 , wherein the tissue approximation device and the tissue closure device are separate and independent instruments.

5. The vaginal tissue closure system of claim 1 , wherein the end effector of the tissue closure device includes a light emitting diode.

6. The vaginal tissue closure system of claim 1 , wherein the first jaw member supports the at least one suture, the at least one suture having a distal end portion, and wherein the second jaw member supports a capture tool defining a receiving aperture, the receiving aperture configured to capture the distal end portion of the at least one suture when the first and second jaw members are disposed in the closed position so that the distal end portion of the at least one suture separates from the first jaw member as the first and second jaw members move from the closed position to the open position.

7. The vaginal tissue closure system of claim 1 , wherein the at least one suture includes an end loop defined therein through which the at least one suture can be threaded to facilitate tying of the at least one suture to vaginal tissue.

8. The vaginal tissue closure system of claim 1 , wherein the at least one suture includes a plurality of sutures, the plurality of sutures simultaneously deployable from the end effector when the end effector is actuated.

9. The vaginal tissue closure system of claim 1 , wherein the paddle extends to a lip defining a distal curl configured to conform to vaginal tissue, the distal lip defining at least one slot therethrough configured to enable the at least one suture to pass therethrough.
