Abstract: Catheter including an inner tubular member, an outer tubular member movable relative to the inner tubular member, and an expandable member coupled to the distal end portion of the inner tubular member. The expandable member having an inner chamber and transitionable between a deflated configuration and an inflated configuration. A pressure chamber is defined by the proximal seal, the distal seal, the exterior surface of the inner tubular member and interior surface of the outer tubular member, with the pressure chamber in fluid communication with a fluid flow port, wherein fluid introduced through the fluid flow port and into the pressure chamber applies a force on the proximal seal to urge the outer tubular member in a proximal direction.
