Abstract: Various embodiments for a stent delivery device or catheter system that includes a stent disposed between an inner shaft and an outer sheath. A housing is coupled to the inner shaft and outer sheath with a rotary reel disposed in the housing and configured for rotation with respect to the housing. A hypotube is disposed in the housing and fixed thereto with the inner shaft extending into the opening of the hypotube and the outer sheath enshrouding a portion of the hypotube. Rotation of the rotary reel in a first direction pulls the outer sheath over the hypotube along the generally circular path to retract the outer sheath from the stent. In some embodiments, a rapid deployment mechanism allows for retracdtion of the outer sheat at an increased rate.

Abstract: Mechanisms for pulling a tensile member a predetermined distance from a medical device having an intracorporeal end and an extracorporeal end are disclosed. Such mechanisms may be safely operated using a robot, two hands, or in some embodiments, only one hand. Such mechanisms may include one or more cams, drums, or pulley-like members and a lever, and may be physically coupled to an extracorporeal portion of the medical device.

Abstract: A stent attachment and deployment mechanism is utilized to prevent the distal end of an endoprosthesis comprising fixation barbs or other fixation mechanism from deploying prior to the remaining sections of the fixation device. With this stent attachment and deployment mechanism accurate deployment may be achieved.

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.
