Vascular prosthetic delivery device and method of use
First Claim
1. A delivery device, comprising,a) a gear rack (106);
- b) a proximal handle (36) extending about the gear rack (106) and defining teeth (156) at an end of the proximal handle (36), the proximal handle (36) being rotatable about the gear rack (106);
c) a pinion gear assembly (164) rotatable about an axis that intersects with the axis of rotation of the proximal handle (36) and engages the gear rack (106);
d) a linking gear assembly (158) that is engaged with the teeth (156) of the proximal handle (36) and selectively rotates with rotation of the pinion gear assembly (164);
e) an actuator (80) that selectively engages the pinion gear assembly (164) with the linking gear assembly (158);
f) a delivery catheter (28) fixed to the proximal handle (36), whereby rotation of the proximal handle (36) selectively moves the delivery catheter (28) relative to the gear rack (106) upon engagement of the pinion gear assembly (164) with the linking gear assembly (158) by the actuator (80);
g) a handle body (20) having a major longitudinal axis (22), a proximal end (24) and a distal end (26), wherein the gear rack (106) extends longitudinally within the handle body (20) and wherein the proximal handle (36) extends about the handle body (20); and
h) a distal handle (40) that extends around the handle body (20) at the distal end (26) of the handle body (20).

Abstract
Methods for delivering a vascular prosthesis to a treatment site of a subject include advancing the vascular prosthesis, rotating a proximal handle in a first direction about a handle body, shifting the position of a first locking component securing the proximal handle to the push rod from a first position to a second position, rotating the proximal handle in a second direction, releasing the proximal end of the prosthesis from the apex delivery device, shifting the second locking component to disengage the push rod from the handle body; and withdrawing the push rod and the guidewire catheter from within the prosthesis, thereby delivering the vascular prosthesis to the treatment site.
