Delivery system having a single handed deployment handle for a retractable outer sheath
First Claim
1. A delivery system for delivering a prosthesis, the delivery system comprising:
- a housing;
a sheath extending from within the housing;
a clutching mechanism housed within the housing, the clutching mechanism including 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, wherein the actuator is accessible from an exterior of the housing;
a cable having a first end coupled to a proximal portion of the sheath and a second end coupled to a storage drum of the inner shaft assembly, wherein 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 around the storage drum and retract the sheath; and
an access wheel within the housing, wherein an intermediate portion of the cable is wound around the access wheel, and wherein the housing includes a window formed through the housing, the window being located adjacent to the access wheel.

Abstract
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.

10. A delivery system for delivering a prosthesis, the delivery system comprising:
-
a handle having a housing; a sheath extending from within the housing; a clutching mechanism housed within the housing, the clutching mechanism including an actuator, an inner shaft assembly, and a one-way clutch disposed between actuator and the inner shaft assembly, wherein the one-way clutch transmits a torque from the actuator to the 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; a cable having a first end coupled to a proximal portion of the sheath and a second end coupled to the inner shaft assembly, wherein 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 to allow the prosthesis to expand to an deployed configuration; and a locking mechanism configured to transfer the actuator between a storage configuration in which the actuator is substantially flush with an outer surface of the housing and an operational configuration in which the actuator is spaced outwardly from the outer surface of the housing. - View Dependent Claims (11, 12, 13, 14, 15)

16. A delivery system for delivering a prosthesis, the delivery system comprising:
-
a housing; a sheath extending from within the housing; a clutching mechanism housed within the housing, the clutching mechanism including, an actuator accessible from an exterior of the housing, an outer shaft coupled to the actuator such that rotation of the actuator in a first direction causes rotation of the outer shaft in the first direction and rotation of the actuator in a second direction causes rotation of the outer shaft in the second direction opposite the first direction, an inner shaft disposed concentrically within the outer shaft, the inner shaft having a first portion and a second portion, a one-way clutch disposed concentrically between the first portion of the inner shaft and the outer shaft, wherein the one-way clutch transmits a torque from the outer shaft to the first portion of the inner shaft when the actuator is rotated in the first direction and does not transmit a torque from the actuator to the first portion of the inner shaft when the actuator is rotated in the second opposing direction, a storage drum disposed concentrically around the second portion of the inner shaft, wherein the storage drum is coupled to the second portion of the inner shaft such that rotation of the first portion of the inner shaft causes rotation of the second portion of the inner shaft and rotation of the second portion of the inner shaft causes rotation of the storage drum, wherein the storage drum is coupled to the second portion of the inner shaft via mating non-circular surfaces between the storage drum and the second portion of the inner shaft; and a cable having a first end coupled to a proximal portion of the sheath and a second end coupled to the storage drum, wherein actuation of the actuator causes the actuator to rotate in the first direction, thereby causing the storage drum to wind up a portion of cable and retract the sheath, and wherein release of the actuator causes the outer shaft to rotate in the second direction but does not cause the storage drum to rotate. - View Dependent Claims (17, 18, 19, 20)
