Abstract
A catheter body includes an exit port over which a pressure responsive sleeve is formed that allows material to exit a lumen of the catheter body at a given pressure. In one embodiment, a surface of the sleeve is approximately flush with a surface of the catheter body.
Claims10
A medical device comprising:
- a catheter body having proximal and distal ends and including an interior surface defining a lumen and an exterior surface having an outer circumference;
- an exit port formed within a distal portion of the catheter body to allow material to exit the lumen of the catheter body;
- and
- a pressure responsive elastic sleeve having proximal and distal ends, located around the exterior surface and covering the exit port, expandable from a closed position to an open position;
- and
- wherein the distal end of the sleeve valve is sealed to the catheter body around the circumference of the exterior surface of the catheter body.
