ABSTRACT:
An access device, such as a gastrostomy tube, includes a Mallincott anchoring structure reinforced with an insert and operable by a pair of sutures. An electrosurgical obturator is positioned in the tube and functions as a stylet for placing the structure in a low profile state. The obturator can then be activated to insert the tube through the abdominal wall and the stomach wall to provide access to the stomach cavity. The sutures can then be tensioned to raise the Mallincott structure to a high profile state and draw the stomach into proximity with the abdominal wall. Removing the obturator leaves the tube operatively disposed and providing direct access to the stomach cavity.
