摘要： A stent deployment system is disclosed. The system has a stent positioned on the distal end of a delivery catheter and a retractable sheath covering the stent. The retractable sheath has one or more wires connected thereto to facilitate retraction of the sheath from off of the stent. The one or more wires extend from the sheath along a portion of the outer surface of the delivery catheter and then enter one or more lumens within the delivery catheter through which the one or more wires extend toward a retraction mechanism. The application of a proximally directed force upon the one or more wires causes the one or more wires and the sheath to move proximally relative to the delivery catheter and the stent, thereby uncovering the stent. Once uncovered, the stent can be expanded to provide scaffolding support a patient's luminal wall.
