Abstract
A method for closing an opening in a wall of a body lumen wherein an elongate member is advanced into the body lumen and a distal portion of an obturator is positioned distally beyond the distal end of the elongate member within the body lumen and in which one or more expandable elements on the distal portion of the obturator are expanded. The obturator is then withdrawn until the expandable elements contact the wall of the body lumen and a clip having tines is advanced over the elongate member until the tines penetrate the wall of the body lumen. The tines and the expandable elements are offset from one another. The elongate member is withdrawn from the body lumen and the clip substantially closes the opening in the body lumen.
