APPARATUS AND METHOD FOR SURGICALLY ACCESSING A BODY CAVITY

摘要

This invention is an access device (10) including an anchoring structure (50) reinforced with an insert (61) and operable by a pair of sutures (65, 67). An electrosurgical obturator (25) is positioned in the tube (10), and functions to place the structure in a low profile state. The obturator (25) can be activated to insert the tube (10) through the abdominal wall (14) and the stomach wall (18) to provide access to the stomach cavity. The sutures (65, 67) can be tensioned to raise the anchoring structure (50) to a high profile state, and draw the stomach into proximity with the abdominal wall. Removing the obturator (25) leaves the tube (10) operatively disposed and providing direct access to the stomach cavity.
