Abstract
A device for percutaneous delivery of a stented prosthetic heart valve. The device includes a sheath, a handle, and an outer stability tube. The sheath includes a distal capsule and a proximal shaft. The handle has a housing maintaining an actuator mechanism that is coupled to the shaft. The actuator mechanism is configured to selectively move the shaft, and thus the capsule, relative to the housing. The stability tube is coupled to the housing and is coaxially received over the shaft such that the shaft is slidable relative to the stability tube. In a delivery state, the capsule encompasses the prosthetic valve. In a deployed state, the capsule is withdrawn from the prosthetic valve. The shaft slides relative to the stability tube in transitioning from the loaded state to the deployed state. When used with an introducer device, the stability tube frictionally isolates the sheath.
