DELIVERY SYSTEM FOR SELF-EXPANDING STENT, A METHOD OF USING THE DELIVERY SYSTEM, AND A METHOD OF PRODUCING THE DELIVERY SYSTEM

摘要

A medical appliance is provided that includes an outer sheath (13) adapted to enclose a self-expanding stent (12) in an inner space before deployment of the self-expanding stent and an inner sheath (16) arranged between the outer sheath and the self-expanding stent before deployment of the self-expanding stent. The inner sheath includes longitudinal slits (21a - 21d) that extend from a distal end of the medical appliance to the proximal end. The longitudinal slits form a plurality of inner sleeve tails (20a - 20d). The medical appliance also includes an actuator (70) adapted to move the outer sheath with respect to the inner sheath during deployment of the self-expanding stent. The actuator is adapted to cause the outer sheath to move proximally. A method of deploying a self-expanding stent is provided. A method of loading a delivery mechanism is provided.
