Abstract
A stent and catheter for implanting or removing a helical-shaped stent within a body passageway; the catheter having an elongate sheath capable of being secured to one end of the stent at a distal region of the sheath and an inner member extending from the sheath, and capable of being secured to the other end of the stent. The inner member is rotatable relative to the sheath to transmit torque to the stent to permit unwinding of the helical stent as its limiting strain to expand the stent. Also discussed are methods for performing procedures for implanting or removing a helical stent from a body passageway.
