Abstract
A medical appliance is provided that includes an outer sheath adapted to enclose a self-expanding stent in an inner space before deployment of the self-expanding stent and an inner sheath arranged between the outer sheath and the self-expanding stent before deployment of the self-expanding stent. The inner sheath includes longitudinal slits that extend from a distal end of the medical appliance to the proximal end. The longitudinal slits form a plurality of inner sleeve tails. The medical appliance also includes an actuator 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.
