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 first 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, wherein the inner shaft assembly includes,an inner shaft component,a storage drum, the storage drum being concentrically disposed around a first portion of the inner shaft component and the first one-way clutch being concentrically disposed around a second portion of the inner shaft component,a second one-way clutch, anda bearing that is coupled to the housing and extends into or over the second one-way clutch, wherein the bearing prevents the second one-way clutch and the storage drum from rotating in the second direction; 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.

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 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 a first actuator to an inner shaft assembly when the first actuator is rotated in a first direction and does not transmit a torque from the first actuator to the inner shaft assembly when the first actuator is rotated in a second opposing direction, wherein the first 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 the inner shaft assembly, wherein actuation of the first actuator causes the first actuator to rotate in the first direction, thereby causing the inner shaft assembly to wind up a portion of cable and retract the sheath; and a spring disposed within the housing and extending between the first actuator and a second actuator accessible from the exterior of the housing, the spring moveable from a loaded locked position in which a first end of the spring is secured within a first recess of the second actuator to an open unlocked position in which a second end of the spring pushes the first actuator radially away from 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; an actuator accessible from an exterior of the housing; an inner shaft assembly disposed within the housing, the inner shaft assembly including an inner shaft component, a transmitting one-way clutch, a storage drum concentrically disposed around or within the transmitting one-way clutch, and a bearing coupled to the housing and extending into or over the transmitting one-way clutch; a driving one-way clutch disposed between the actuator and a first portion of the inner shaft component of the inner shaft assembly, wherein the driving 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; and a cable having a first end coupled to a proximal portion of the sheath and a second end coupled to the storage drum of the inner shaft assembly, 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 release of the actuator causes the actuator to rotate in the second direction, wherein the bearing prevents the transmitting one-way clutch and storage drum from rotating in the second direction. - View Dependent Claims (17, 18, 19, 20)
