PROXIMAL RELEASE DELIVERY SYSTEM
First Claim
1. A device for deploying an intraluminal device, comprising:
- a gear and pulley mechanism comprising a first gear set and a second gear set;
a drive pulley adapted to be mechanically coupled to one of the first gear set and the second gear set;
an introducer sheath operably connected to the drive pulley; and
an expandable prosthesis constrained within the introducer sheath,wherein the sheath is movable in a distal direction relative to the prosthesis when the drive pulley is mechanically coupled to the first gear set so as to release the prosthesis from a proximal end thereof, and further wherein the sheath is retractable in a proximal direction relative to the prosthesis when the drive pulley is mechanically coupled to the second gear set so as to resheath over the prosthesis.

Abstract
A delivery device for proximally releasing an expandable prosthesis and method of use thereof are described. The delivery device comprises an introducer sheath that is capable of distally advancing relative to the endoprosthesis to thereby expose the endoprosthesis from a proximal end thereof. The device is also capable of resheathing over the prosthesis in a proximal direction. The device comprises a drive pulley that can engage a particular gear set to axially move the introducer sheath and proximally release the prosthesis. The drive pulley can also engage another gear set to resheath the introducer sheath and recapture the prosthesis between the inner catheter and the introducer sheath. A directional switch enables the device to operate between the two modes.

11. A device for delivering an intraluminal device, comprising:
a housing comprising; a gear and pulley mechanism comprising a first gear set and a second gear set; and a drive pulley adapted to be mechanically coupled to one of the first gear set and the second gear set, an elongate member fixably connected to a distal end of the housing; an expandable prosthesis having a first proximal end and a first distal end, the prosthesis mounted over a distal portion of the inner elongate member; a stabilizing assembly for securing the first distal end of the prosthesis to the inner elongate member; and an introducer sheath axially movable over the prosthesis, the sheath having a second distal end positioned distal to the first distal end of the prosthesis and a second proximal end positioned proximal to the first proximal end of the prosthesis, wherein the sheath is operably connected to the drive pulley so as to allow the second proximal end of the sheath to slidably advance distally relative to the first proximal end of the prosthesis to thereby expose a proximal portion of the prosthesis. - View Dependent Claims (12, 13, 14, 15, 16)

17. A device for delivering an intraluminal device comprising:
-
a first gear set and a second gear set; a drive pulley adapted to be alternatively mechanically coupled to the first gear set and the second gear set; a belt coupled to the drive pulley; an introducer sheath mechanically coupled to the belt; and an expandable prosthesis constrained within the introducer sheath, wherein the belt is configured to rotate in a clockwise direction when the drive pulley is mechanically coupled to the first gear set to distally advance the sheath beyond a proximal end of the prosthesis so as to release a proximal portion of the prosthesis from within the sheath, and further wherein the belt is configured to rotate in a counterclockwise direction when the drive pulley is mechanically coupled to the second gear set to proximally retract the sheath over the prosthesis. - View Dependent Claims (18, 19, 20)
