Patent ID: 7875041

Claim:
A suturing method for a penetrating hole formed in a stomach using a suture material passing through a hole of a stopper to close the penetrating hole comprising the steps of: inserting a needle at insertion positions that are separated from an open edge of said penetrating hole by a distance that is less than a thickness of a wall of said stomach from a mucosa side of said stomach, and passing said needle through said wall; sending out from said needle an anchor affixed to an end of the suture material; placing said anchor in place by pulling said needle through said wall and passing said suture material through said wall; adhering muscular tunics of said stomach together by tightening said suture material so that said stopper and said stomach contact with each other and all of the insertion positions and the hole of said stopper approximately coincide with each other by advancing said stopper relative to said suture material so that a distance between said stopper and said anchor is decreased after passing said suture material in the same direction through said wall at multiple sites interposing said penetrating hole.
