Delivery device
First Claim
1. An apparatus for delivering 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 alternatively mechanically coupled to the first gear set and the second gear set; and
a sheath disposed over an inner elongate member, the sheath being in mechanical communication with the drive pulley and adapted to retract in a proximal direction and resheath in a distal direction.

Abstract
A delivery device for deploying an expandable prosthesis and method of use thereof are described. The delivery device comprises an outer catheter that is capable of retracting in a proximal direction and resheathing over the prosthesis in a distal direction. The device comprises a drive pulley that can engage a particular gear set to retract the outer catheter and expose the prosthesis. The drive pulley can also engage another gear set to resheath the outer catheter and recapture the prosthesis between the inner and the outer catheter. A directional switch enables the device to operate between the two modes.

20. An apparatus for delivering an intraluminal device, comprising:
-
a gear and pulley mechanism comprising a first gear set and a second gear set; an inner elongate member, the inner elongate member being fixed at a proximal end to a handle assembly; an outer elongate sheath disposed over the inner elongate member, the outer elongate sheath being coupled to a belt wound around a drive pulley, the outer elongate sheath adapted to be actuated by the first gear set rotating the drive pulley to be movable in a distal direction relative to the inner elongate member, the outer elongate sheath being adapted to be actuated by the second gear set rotating the drive pulley to be movable in a proximal direction relative to the inner elongate member; and a stabilizing element extending along a longitudinal axis of the inner member and the outer elongate sheath for fixating the position of the intraluminal device during movement of the outer elongate sheath relative to the inner elongate member. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method for resheathing an intraluminal device, comprising the steps of:
-
(a) providing a delivery apparatus comprising; a gear and pulley mechanism 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; and a retractable sheath disposed over an inner elongate member, the retractable sheath mechanically coupled to the drive pulley by a belt; (b) engaging the drive pulley with the first gear set; and (c) activating a trigger to cause the drive pulley to rotate the belt with the sheath thereon in a distal direction relative to the inner elongate member. - View Dependent Claims (31, 32, 33, 34)
