Delivery System Having a Single Handed Deployment Handle for a Retractable Outer Sheath

摘要

A delivery system for delivering a prosthesis, the delivery system including a housing, a sheath extending from within the housing, a clutching mechanism housed within the housing, and a cable. The clutching mechanism includes a one-way clutch that transmits a torque from an actuator to an inner shaft assembly when the actuator is rotated in a first direction and does not transmit a torque from the actuator to the inner shaft assembly when the actuator is rotated in a second opposing direction. The actuator is accessible from an exterior of the housing. The cable has a first end coupled to a proximal portion of the sheath and a second end coupled to the inner shaft assembly, and actuation of the actuator causes the actuator to rotate in the first direction, thereby causing the inner shaft assembly to wind up a portion of cable and retract the sheath.
