Patent Images
1. A method for delivering a prosthesis to a body lumen, said method comprising:
- positioning a delivery catheter at a target site, the tubular catheter comprising;
an outer tube having a passage;
a tubular prosthesis carried in the passage of the outer tube at least partially in a radially collapsed configuration; and
an inner tube slidably disposed within the passage of the outer tube, the inner tube having a lumen for receiving a guidewire; and
advancing the inner tube distally relative to the outer tube to evert the tubular prosthesis so that an inside surface is exposed radially outwardly and advanced over a length of a wall of the body lumen.

Abstract
Blood vessels and other body lumens are expanded using an evertible braided prosthesis. The braided prosthesis is delivered to the blood vessel in a radially collapsed configuration. A leading edge of the braided prosthesis is then everted so that it expands as it is advanced through the blood vessel. Optionally, the prosthesis can be provided with a biologically active substance in order to inhibit hyperplasia or have other desired biological effects.
