1. A delivery catheter comprising:
- a catheter shaft having a proximal end and a distal end;
an expansion member disposed near the distal end of the shaft;
an expandable prosthesis mounted over the expansion member; and
a guidewire structure disposed over the expansion member, beneath a proximal portion of the prosthesis, and extending to a holding location spaced proximally of a side hole of the prosthesis by a distance of at least 1 mm.

Abstract
A catheter for delivering luminal prostheses comprises a catheter body having an expandable member near a distal end. The prosthesis has a side hole, and a guidewire extends beneath a proximal portion of the prosthesis and over the exterior of the expandable member. A distal end of the guidewire is retracted proximally from the closest point on the side opening to reduce possible interference with catheter advancement.
