Abstract
A delivery catheter comprises a first, flexible, polymer-based tube and a second, metal tube at the first tube distal end. The second tube has flexibility enhancing relief areas along its length to provide localized areas of reduced bending stiffness to enhance the bending flexibility while retaining good torsional stiffness. A notched catheter has a lumen and a notched outer surface intersecting the lumen with a filament-containing layer adjacent to the outer surface. A part of the filament-containing layer is capturable between the notched surface portion and an elongate element extendable through the lumen. A generally helically coiled endoluminal prosthesis may be mounted on a pre-torqued delivery catheter to tighten the coiled endoluminal prosthesis onto the delivery catheter.
