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. A surgical method for closing an opening in an organ wall, the surgical method comprising:
positioning a distal end portion of a steerable overtube adjacent a portion of the organ wall through which the opening extends;
inserting a flexible clip magazine into the steerable overtube, the flexible clip magazine supporting a plurality of tissue apposition clips therein such that upper and lower clip arms thereof are supported in a spaced open position relative to each other, the flexible clip magazine having a distal end portion received within the distal end portion of the steerable overtube such that the plurality of tissue apposition clips supported therein may be selectively discharged out through the distal end portion of the steerable overtube;
extending a grasper beyond the distal end portion of the steerable overtube and beyond a foremost apposition clip in the plurality of tissue apposition clips, wherein the foremost apposition clip is the distal-most apposition clip in the plurality of tissue apposition clips;
after extending the grasper beyond the steerable overtube and the foremost apposition clip, grasping tissue with the grasper through which the opening extends;
after grasping the tissue with the grasper, pulling a portion of the grasped tissue with the grasper into a clamping position between upper and lower clip arms of the foremost apposition clip supported within the distal end portion of the flexible clip magazine; and
advancing the foremost apposition clip onto the portion of the grasped tissue.
2. The surgical method of claim 1 further comprising:
repositioning the distal end portion of the steerable overtube adjacent another portion of the opening;
grasping other tissue through which the opening extends;
drawing a portion of the grasped other tissue into a clamping position between upper and lower clip arms of another distal-most one of the tissue apposition clips supported within the distal end portion of the flexible clip magazine; and
advancing the another distal-most tissue apposition clip onto the portion of the grasped other tissue.
3. The surgical method of claim 1 wherein the opening in the organ wall is selected from a group of openings consisting of an opening in a stomach, an opening in a colon, an opening in a vagina, and an opening in an esophagus.
4. The surgical method of claim 1 further comprising clamping the the foremost apposition clip onto the portion of the grasped tissue when the portion of the grasped tissue is drawn into the clamping position between the upper and lower clip arms.
5. A surgical method for closing an opening in an organ wall, the surgical method comprising:
positioning a distal end portion of a steerable overtube adjacent a portion of the organ wall through which the opening extends;
positioning a distal end portion of a flexible clip magazine within the distal end portion of the steerable overtube, the flexible clip magazine supporting a plurality of tissue apposition clips;
extending a grasper beyond the distal end portion of the steerable overtube and beyond a foremost apposition clip in the plurality of tissue apposition clips, wherein the foremost apposition clip is the distal-most apposition clip in the plurality of tissue apposition clips;
after extending the grasper beyond the steerable overtube and the foremost apposition clip, grasping tissue with the grasper through which the opening extends;
after grasping the tissue with the grasper, pulling a portion of the grasped tissue with the grasper into a clamping position between upper and lower clip arms of the foremost apposition clip supported within the distal end portion of the clip magazine; and
advancing the foremost apposition clip onto the portion of the grasped tissue.
6. The surgical method of claim 5 , further comprising:
repositioning the distal end portion of the steerable overtube adjacent another portion of the opening;
grasping other tissue through which the opening extends;
drawing a portion of the grasped other tissue into a clamping position between upper and lower clip arms of another distal-most one of the tissue apposition clips supported within the distal end portion of the flexible clip magazine; and
advancing the another distal-most tissue apposition clip onto the portion of the grasped other tissue.
7. The surgical method of claim 5 , wherein the opening in the organ wall is selected from a group of openings consisting of an opening in a stomach, an opening in a colon, an opening in a vagina, and an opening in an esophagus.
8. The surgical method of claim 5 , further comprising clamping the the foremost apposition clip onto the portion of the grasped tissue when the portion of the grasped tissue is drawn into the clamping position between the upper and lower clip arms.
