Claim:
1. A method for delivering a vascular prosthesis to a treatment site of a subject, comprising the steps of: a) advancing the vascular prosthesis, while the vascular prosthesis is mounted at a proximal end of the prosthesis to an apex delivery device that is fixed to a distal end of a guidewire catheter, to a position distal to a vascular treatment site of the subject; b) rotating a proximal handle in a first direction about a handle body, having a distal end, of a delivery device through which the guidewire catheter extends, the guidewire catheter disposed within a push rod that also extends through the handle body, wherein the guidewire catheter is fixed to the push rod, whereby rotation of the proximal handle causes longitudinal movement of the guidewire catheter and the push rod along the handle body to thereby at least partially advance the prosthesis to the treatment site, the prosthesis being advanced from within an outer catheter extending from a distal end of the handle body and about the prosthesis; c) shifting the position of a first locking component securing the proximal handle to the push rod from a first position to a second position, whereby the first locking component disengages the proximal handle from the push rod and a second locking component engages the push rod with the handle body; d) rotating the proximal handle in a second direction, whereby a delivery catheter having a distal end, the delivery catheter extending about the push rod, is withdrawn along the push rod, and a delivery sheath extending from the distal end of the delivery catheter is at least partially retracted from about the prosthesis; e) releasing the proximal end of the prosthesis from the apex delivery device; f) shifting the second locking component to disengage the push rod from the handle body; and g) withdrawing the push rod and the guidewire catheter from within the prosthesis, thereby delivering the vascular prosthesis to the treatment site.
