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 tissue closure system, comprising:
a vacuum source;
a tissue approximation device having a paddle including a suction aperture defined therein, the suction aperture in fluid communication with the vacuum source to apply negative pressure to tissue to maintain the tissue in close proximity to the paddle; and
a tissue closure device including movable jaw members supporting at least one suture, the jaw members actuatable between open and closed positions to selectively grasp the tissue and to position the at least one suture in the tissue for closing an opening formed in the tissue.

2. The 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 tissue closure system of claim 1 , wherein the jaw members are pivotably coupled together.

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

5. The tissue closure system of claim 1 , wherein at least one of the jaw members includes a light emitting diode.

6. The tissue closure system of claim 1 , wherein the jaw members include a first jaw member and a second jaw member, the first jaw member supporting the at least one suture.

7. The tissue closure system of claim 1 , wherein the second jaw member supports a capture tool defining a receiving aperture, the receiving aperture configured to capture the at least one suture.

8. The 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 tissue.

9. The tissue closure system of claim 1 , wherein the at least one suture includes a plurality of sutures, each suture of the plurality of sutures being simultaneously deployable.

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

11. A method of closing opened vaginal cuff tissue, the method comprising:
applying negative pressure through at least one paddle of a tissue approximation device to vaginal cuff tissue surrounding an opening defined between the vaginal cuff tissue;
manipulating the at least one paddle of the tissue approximation device to approximate the vaginal cuff tissue and position the opening in a closed state; and
suturing the vaginal cuff tissue to maintain the opening of the vaginal cuff tissue in a closed state.
