1. A delivery device, comprising:
- a) a guidewire catheter having a proximal end and a distal end; and
b) a delivery assembly extending about the guidewire catheter, including;
i) a handle body, having a major longitudinal axis, a proximal end and a distal end,ii) a delivery catheter having a distal end extending from within the distal end of the handle body and about the guidewire catheter,iii) a push rod extending about the guidewire catheter and within the delivery catheter, the push rod being fixed to the guidewire catheter at the proximal end of the guidewire catheter proximal to the handle body,iv) a proximal handle extending about the handle body and axially fixed to the delivery catheter, the proximal handle being selectively fixed to the push rod, wherein the proximal handle is rotatable about the handle body and rotation of the proximal handle about the handle body translates to longitudinal movement of the delivery catheter and, selectively, of the push rod relative to the handle body,v) a locking mechanism at the handle body that selectively engages the proximal handle with the push rod, andvi) an actuator at the proximal handle that selectively disengages the proximal handle from the handle body, whereby rotation of the proximal handle is independent of longitudinal movement of the delivery catheter relative to the handle body.

Abstract
A delivery device includes a guidewire catheter and a delivery assembly extending about the guidewire catheter. The delivery assembly includes a locking mechanism that selectively engages a proximal handle of the delivery assembly with a push rod to which a vascular prosthesis is directly or indirectly attached. When an actuator selectively disengages the proximal handle from the handle body, rotation of the proximal handle is independent of longitudinal movement of the vascular prosthesis relative to the handle body, whereby the proximal handle can be moved along the handle body with rotation.

16. A delivery device, comprising,
a) a gear rack; -
b) a handle extending about the gear rack and defining teeth at an end of the handle, the handle being rotatable about the gear rack; c) a pinion gear rotatable about an axis that intersects with the axis of rotation of the handle and engages the gear rack; d) a linking gear that selectively rotates with rotation of the pinion gear; e) an actuator that selectively engages the pinion gear with the linking gear; and f) a delivery catheter fixed to the handle, whereby rotation of the handle selectively moves the delivery catheter relative to the gear rack upon engagement of the pinion gear with the linking gear by the actuator.
