Patent ID: 11129713

Abstract:
A prosthetic heart valve delivery system can include a catheter portion having a sheath that can cover and uncover the prosthetic heart valve mounted on an inner shaft, a handle having a sheath actuator operatively coupled to a proximal portion of the sheath, the inner shaft extending through the handle, and a shaft retractor releasably coupled to a proximal portion of the handle and fixedly coupled to a proximal portion of the inner shaft. A sheath actuator can move the sheath axially relative to the inner shaft when the shaft retractor is coupled to the handle, and a proximal movement of the sheath relative to the inner shaft can cause the sheath to uncover the prosthetic heart valve. The shaft retractor can be operable to retract the inner shaft and the nosecone proximally relative to the sheath when the shaft retractor is released from the handle.
