Abstract
An anti-obesity balloon and a placement system for the balloon includes a balloon with a needle-pierceable, self-sealing plug and an insertion catheter having a needle at its distal end. The needle is movable between an extended position in which it protrudes distally of the insertion catheter and a retracted position in which it is withdrawn interiorly of the insertion catheter. A handle arrangement is provided at the proximal end of the insertion catheter to control the position of the needle. Means are provided for aspirating and inflating the balloon. The balloon structure and insertion catheter structure protect and enclosed the sharp tip of the needle at all times during insertion and withdrawal of the insertion catheter. The insertion catheter is detachable from the balloon, after the balloon has been inflated in the patient's stomach, in a manner which imposes no force or load on the balloon.
