Handle system for deploying a prosthetic implant
First Claim
1. A handle system of a delivery catheter for delivering a prosthetic implant device, the handle system comprising:
- a first stationary portion;
at least one guide rail secured to the first stationary portion and extending generally longitudinally with the handle system;
a generally cylindrical second rotating portion rotably connected to the first stationary portion, the second rotating portion having a threaded internal surface; and
a sheath mount secured to an outer sheath of the delivery catheter, including one or more bearing surfaces to engage with at least one of the one or more guide rails, and further having a generally cylindrical outer surface with a configuration to engage the internal threaded surface of the second rotating portion;
wherein rotation of the second rotating portion longitudinally displaces the sheath mount by interaction of the threaded internal surface with the configuration of the generally cylindrical outer surface.

Abstract
A handle system of a delivery catheter for the deployment of prosthetic implants includes a first stationary portion, at least one guide rail secured to the first stationary portion and extending generally longitudinally with the handle system, and a generally cylindrical second rotating portion rotably connected to the first stationary portion. A sheath mount is secured to an outer sheath of the delivery catheter, and includes one or more bearing surfaces to engage with at least one of the one or more guide rails. Rotation of the second rotating portion longitudinally displaces the sheath mount by interaction with the sheath mount. Interaction may be by internal thread of the rotating portion and external thread of the sheath mount, or alternately by rotating one or more drive screws by turning the rotating portion, the drive screws interacting with through holes in the sheath mount configured to receive and engage the drive screws.

30. A handle system of a delivery catheter for delivering a prosthetic implant device, the handle system comprising:
-
a first stationary portion;
at least one guide rail secured to the first stationary portion and extending generally longitudinally with the handle system;
a second rotating portion rotably connected to the first stationary portion, having a central opening with internal gear teeth;
one or more drive screws extending generally longitudinally with the handle system, each drive screw having a spur gear at a proximal end thereof, the spur gears communicating with the internal gear teeth of the central opening to rotate together with the second rotating portion; and
a sheath mount secured to an outer sheath of the delivery catheter, including one or more bearing surfaces to engage with at least one of the one or more guide rails, and further having one or more through holes with a configuration to engage one or more drive screws;
wherein rotation of the second rotating portion longitudinally displaces the sheath mount by interaction of the drive screws with the configuration of the one or more through holes in the sheath mount. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58)
