STENT-VALVE DELIVERY SYSTEM

Abstract

A delivery system for delivering a stent-valve may include an inner shaft including a distal tip, a stent-valve crimped onto the inner shaft, a distal sheath disposed over at least a lower portion of the stent-valve, and a proximal sheath disposed over at least an upper portion of the stent-valve. The distal sheath has a proximal free end with an angled proximal edge defining a short side and a long side of the distal sheath. The proximal sheath is actuatable independently from the distal sheath, and moveable proximally to release the upper portion of the stent-valve. The distal sheath is moveable distally to release the lower portion of the stent-valve. The angled proximal edge releases a first side of the lower portion of the stent-valve before an opposite second side.
