DELIVERY DEVICE
First Claim
1. A delivery device for delivering an intraluminal device, comprising:
- a gear mechanism comprising a first gear set and a second gear set;
the gear mechanism configured to selectably mechanically couple a threaded drive shaft to one of the first gear set and the second gear set via a threaded worm gear; and
an outer elongate shaft disposed slidably over an inner elongate shaft, the outer elongate shaft comprising a mechanical communication connection with a first portion of the threaded drive shaft; and
the inner elongate shaft comprising a mechanical communication connection with a second portion of the threaded drive shaft;
wherein the gear mechanism is configured such that actuation of the first gear set rotates the threaded drive shaft in a first direction, and actuation of the second gear set rotates the threaded drive shaft in a second direction that is opposite the first direction;
wherein the first portion of the threaded drive shaft is threaded opposite the second portion of the threaded drive shaft; and
wherein the mechanical communication connection of the outer shaft with the first portion of the threaded drive shaft and the mechanical communication connection of the inner shaft with the portion of the threaded drive shaft are configured to move the inner and outer shafts in opposite longitudinal directions from each other upon rotation of the threaded drive shaft.

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.

13. A delivery device configured for delivering an intraluminal device, comprising:
-
a threaded driveshaft comprising a longitudinal axis; a gear mechanism comprising a lower gear set comprising at least one deployment gear and at least one resheathing gear sharing a common rotation axis, and an upper gear set comprising a worm gear configured to perpendicularly translate rotation of a selected one of the at least one deployment gear or at least one resheathing gear with which it is engaged into rotation of the driveshaft about its longitudinal axis; an outer elongate shaft disposed slidably over an inner elongate shaft, the outer elongate shaft comprising a mechanical communication connection with a first portion of the threaded drive shaft; and the inner elongate shaft comprising a mechanical communication connection with a second portion of the threaded drive shaft; wherein the gear mechanism is configured such that actuation of the lower gear set rotates the threaded drive shaft in a first direction when the at least one deployment gear is engaged with the worm gear, and actuation of the lower gear set rotates the threaded drive shaft in a second direction that is opposite the first direction when the at least one resheathing gear is engaged with the worm gear; wherein the first portion of the threaded drive shaft is threaded opposite the second portion of the threaded drive shaft; and wherein the mechanical communication connection of the outer shaft with the first portion of the threaded drive shaft and the mechanical communication connection of the inner shaft with the portion of the threaded drive shaft are configured to move the inner and outer shafts in opposite longitudinal directions from each other upon rotation of the threaded drive shaft. - View Dependent Claims (14, 15, 16, 17, 18, 19)
