Patent ID: 8292872

Claim:
An elongate engagement member for use with an elongate medical device comprising a tubular member having a coupling region configured to couple with a wire guide, the coupling region being disposed near a distal end of the tubular member, the elongate engagement member comprising: an elongate shaft extending along a longitudinal axis and having a distal end configured to frictionally engage an exterior surface of the wire guide and an inner wall of a passageway within the tubular member; and a handle assembly adjustably connected to a proximal portion of the elongate shaft, the handle assembly comprising a hub connector configured for engagement with a proximal port of the elongate medical device, the handle assembly further comprising a handle portion movably connected to the hub connector, wherein the elongate engagement member is configured to engage and releasably secure a wire guide coupled with the elongate medical device and prevent relative movement between the wire guide and the elongate medical device; and wherein the handle portion is rotatably connected to the hub connector, and the proximal portion of the elongate shaft is helically connected to the handle portion and slidably connected to the hub connector such that, rotation of the handle portion relative to the hub connector causes longitudinal movement of the elongate shaft along the longitudinal axis and changes a longitudinal position of the distal end of the elongate shaft along the longitudinal axis relative to the handle portion, the hub connector, and the coupling region of the elongate medical device, and thereby alters an overall length of a distal portion of the elongate shaft extending distally from the handle without changing an overall length of the handle assembly.
