ENDOSCOPIC CLOSURE DEVICE
First Claim
1. A tissue closure device, comprising:
- a clip including a plurality of arms extending from proximal ends connected to one another to distal ends, the clip being biased toward an open configuration in which the distal ends extend away from a longitudinal axis of the clip, the arms being held in a closed configuration in which the arms are moved toward the longitudinal axis via an interior surface of a working channel through which the clip is passed until the clip is moved distally past a distal end of the working channel and permitted to revert to the biased open configuration so that the distal ends are positioned about a portion of tissue surrounding a tissue opening to be closed; and
a locking element movable over the arms to lock the clip in the closed configuration in which distal ends of the arms are drawn toward one another to grip tissue therebetween.

Abstract
A tissue closure device includes a clip including arms extending from proximal ends connected to one another to distal ends. The clip is biased toward an open configuration in which the distal ends extend away from a longitudinal axis of the clip. The arms are held in a closed configuration in which the arms are moved toward the longitudinal axis via an interior surface of a working channel through which the clip is passed until the clip is moved distally past a distal end of the working channel and permitted to revert to the biased open configuration so that the distal ends are positioned about a portion of tissue surrounding a tissue opening to be closed. The device also includes a locking element movable over the arms to lock the clip in the closed configuration in which the arms are drawn toward one another to grip tissue therebetween.

31. A method for closing a tissue opening, comprising:
-
inserting a clip through a working channel of an endoscope to a target site within a body, the clip including a plurality of arms extending from proximal ends connected to one another to distal ends, the clip being biased toward an open configuration in which the distal ends extend away from a longitudinal axis of the clip, the arms being held in a closed configuration in which the arms are moved toward the longitudinal axis via an interior surface of the working channel until the clip is moved distally past a distal end of the working channel and permitted to revert to the biased open configuration; positioning the distal ends of the arms about a portion of tissue surrounding a tissue opening; moving the clip to the closed configuration such that the distal ends are moved toward one another to draw edges of the tissue opening toward one another; moving a locking element over the plurality of arms to lock the clip in the closed configuration; and deploying the clip in the body in the closed configuration. - View Dependent Claims (32, 33, 34, 35)
