CATHETER HAVING MOVABLE TUBULAR STRUCTURE

摘要

Catheter including an inner tubular member having a proximal end portion, a distal end portion and an exterior surface. The inner tubular member further has a guidewire lumen defined therein. An outer tubular member is movable relative to the inner tubular member, the outer tubular member has a proximal end, a distal end and an interior surface directed toward the exterior surface of the inner tubular member. A movable tubular structure is disposed between the outer tubular member and the inner tubular member. The movable tubular structure includes a body member having an outer surface with a recess defined therein. The outer tubular member is received within the recess to form a trough along a portion of an exterior surface of the outer tubular member. The trough has a filler disposed therein to couple the outer tubular member to the body member of the movable tubular structure.
