Abstract:
Catheter including an inner tubular member having a fluid lumen defined therein and an exterior surface. The exterior surface defining a first distal flow port and a second distal flow port. An outer tubular member is movable relative to the inner tubular member in a proximal direction and having an interior surface. A first pressure chamber is defined between the exterior surface and the interior surface, and between a first distal seal assembly and a first proximal seal assembly. A second pressure chamber is defined between the exterior surface and the interior surface, and between a second distal seal assembly and a second proximal seal assembly. Fluid introduced through the fluid lumen pressurizes the first pressure chamber and the second pressure chamber to generate a respective force at the first proximal seal assembly and to the second proximal seal assembly to urge the outer tubular member in the proximal direction.
