Abstract:
1. A method for closing an opening in a wall of a body lumen, comprising: advancing a distal end of an elongate member through a passage and into a body lumen; positioning an obturator distally beyond the distal end of the elongate member along the passage within the body lumen; expanding one or more expandable elements of the obturator; withdrawing the obturator from the passage until an expandable element contacts an inner wall of the body lumen, thereby providing a tactile indication of the inner wall of the body lumen; advancing a clip having tines into the passage over the elongate member until the tines of the clip engage the wall of the body lumen; and withdrawing the elongate member from the body lumen and passage, leaving the clip to substantially close the opening in the wall of the body lumen, and a plurality of the tines and the clip translating into a substantially planar configuration.
