Tissue apposition clip application methods
Surgical methods for closing a gastrotomy. The surgical method for closing an opening in an organ wall comprises positioning a distal end portion of a steerable overtube adjacent a portion of the organ wall through which the opening extends. The surgical method further comprises inserting a flexible clip magazine into the steerable overtube. The surgical method comprises grasping tissue through which the opening extends and drawing a portion of the grasped tissue into a clamping position between upper and lower clip arms of a distal-most tissue apposition clip supported within a distal end of the clip magazine. The surgical method further comprises advancing the distal-most tissue apposition clip onto the portion of grasped tissue.
1. The claim has been replaced with
A clip application device for treating tissue, the clip application device comprising:
a flexible tube comprising a remotely articulatable end portion;
a clip magazine having a clip passage therein, wherein the clip magazine is insertable in the flexible tube;
tissue apposition clips stored in the clip passage in a biased-open configuration;
an advancement member for applying an advancement motion to the tissue apposition clips in the clip passage to cause the tissue apposition clips to move out of said clip passage;
a first grasper extending from the flexible tube and configured to grasp the tissue; and
a second grasper extending from the flexible tube and configured to grasp the tissue,
wherein the tissue apposition clips are deployable over the first and second graspers to clip the tissue.
2. The clip application device of claim 1 , wherein the tissue apposition clips are movable by the advancement member in the clip passage in the biased-open configuration.
3. The clip application device of claim 1 , wherein the first and second graspers are movable relative to the tissue apposition clips.
4. The clip application device of claim 1 , wherein each of the tissue apposition clips comprises two clip arms biased away from each other in the clip passage.
5. The claim has been replaced with
A surgical system for treating tissue, the surgical system comprising:
a control unit;
a flexible tube comprising an end portion remotely articulatable by the control unit;
a clip magazine having a clip passage therein, wherein the clip magazine is insertable in the flexible tube;
tissue apposition clips stored in the clip passage in a biased-open configuration;
an advancement member for applying an advancement motion to the tissue apposition clips in the clip passage to cause the tissue apposition clips to move out of said clip passage;
a camera positioned at the end portion, wherein the tissue apposition clips are advanceable distally beyond the camera;
a first grasper extending from the flexible tube and configured to grasp the tissue; and
a second grasper extending from the flexible tube and configured to grasp the tissue,
wherein the tissue apposition clips are deployable over the first and second graspers to clip the tissue.
6. The surgical system of claim 5 , wherein the tissue apposition clips are movable by the advancement member in the clip passage in the biased-open configuration.
7. The surgical system of claim 5 , wherein the first and second graspers are movable relative to the tissue apposition clips.
8. The surgical system of claim 5 , wherein each of the tissue apposition clips comprises two clip arms biased away from each other in the clip passage.
9. The claim has been replaced with
A surgical system for treating tissue, the surgical system comprising:
a control unit;
a flexible tube comprising an end portion remotely articulatable by the control unit, wherein the flexible tube defines a clip passage;
tissue apposition clips stored in the clip passage in a biased-open configuration;
an advancement member for applying an advancement motion to the tissue apposition clips in the clip passage to cause the tissue apposition clips to move out of said clip passage;
a camera positioned at the end portion, wherein the tissue apposition clips are advanceable distally beyond the camera;
a first grasper extending from the flexible tube and configured to grasp the tissue; and
a second grasper extending from the flexible tube and configured to grasp the tissue,
wherein the tissue apposition clips are deployable over the first and second graspers to clip the tissue.
10. The surgical system of claim 9 , wherein the tissue apposition clips are movable by the advancement member in the clip passage in the biased-open configuration.
11. The surgical system of claim 9 , wherein the first and second graspers are movable relative to the tissue apposition clips.
12. The surgical system of claim 9 , wherein each of the tissue apposition clips comprises two clip arms biased away from each other in the clip passage.
