Abstract
An endoscopic clip apparatus includes a clip sleeve defining an interior passage along a longitudinal axis and having a distal end with a plurality of openings defined in the distal end. A clip including a plurality of arms is disposed in the clip sleeve, and each arm includes a distal tip extending from the clip sleeve through one of the plurality of openings. Each arm includes a convex curved section oriented away from the longitudinal axis. The clip sleeve and clip are axially moveable relative to each other such that when the clip sleeve travels over the convex curved section of each arm toward the distal tip of each arm, each arm is constrained by the clip sleeve and each distal tip advances toward the longitudinal axis to grasp tissue.
