Delivery device
First Claim
1. A delivery device for delivering an intraluminal device, comprising:
- an intraluminal device;
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, an outer sheath disposed over an inner elongate member, the sheath being in mechanical communication with the drive pulley so as to retract in a proximal direction and resheath in a distal direction; and
a stabilizing element comprising an anchorage assembly, the anchorage assembly comprising a retaining loop assembly positioned on the inner elongate member and a lockwire, wherein engagement of a distal portion of the lockwire with the retaining loop assembly anchors the intraluminal device to the inner elongate member during movement of the outer sheath relative to the inner elongate member so that in an engaged position of the anchorage assembly, the retaining loop assembly and a portion of the intraluminal device overlap and the lockwire passes through the overlapping retaining loop assembly and the portion of the intraluminal device.

Abstract
A delivery device for deploying an expandable prosthesis and method of use thereof are described. The delivery device includes an outer sheath that is capable of retracting in a proximal direction and resheathing over the prosthesis in a distal direction. The device includes a drive pulley that can engage gears to retract or resheath the outer catheter in relation to the prosthesis. In some embodiments, the delivery device may include a reinforced outer sheath disposed over an inner elongate member, the reinforced outer sheath comprising a proximal section reinforced with a braid, a distal section reinforced with a coil and an overlapping section extending between the proximal section and the distal section. Additionally or alternatively, the delivery device may include a stabilizing element for releasably holding the stent to the inner catheter.
