Endoluminal prostheses having position indicating markers
First Claim
1. An endoluminal prosthesis for deployment in a body lumen of a patient body, the prosthesis comprising:
- a tubular fabric liner having a proximal end, a distal end, and a lumen therebetween;
a radially expandable frame supporting the liner; and
a plurality of imagable bodies attached to the liner, each imagable body comprising a plate having at least one passage therethrough to facilitate attaching the imagable body to the liner, the imagable bodies providing a sharp contrast so as to define a pattern which indicates the prosthesis position when the prosthesis is imaged within the patient body.

Abstract
The present invention provides an endoluminal prosthesis for deployment in a body lumen of a patient body, the prosthesis comprising a tubular fabric liner and a radially expandable frame supporting the liner. A plurality of imagable bodies are attached to the liner, the imagable bodies providing a sharp contrast so as to define a pattern which indicates the prosthesis position when the prosthesis is imaged within the patient body. Preferably, each imagable body comprises a plate having first and second opposed major surfaces and a passage therebetween to facilitate stitching the imagable body to the liner. Advantageously, the imagable bodies can be aligned with the openings of a perforate frame structure so that at least some of the imagable bodies are visible through associated openings, but need not actually be attached to the frame directly. Such imagable bodies are clearly visible when the prosthesis is deployed, and can also be sized to produce distinct images even when the frame is compressed within a delivery catheter, but will not interfere with the radial expansion of the frame during deployment.

17. An endoluminal prosthesis for deployment in a body lumen of a patient body, the prosthesis comprising:
-
a tubular fabric liner having a proximal end, a distal end, and a lumen therebetween; a radially expandable frame supporting the liner, the frame comprising a tube defining a plurality of radial openings when expanded; and a plurality of imagable bodies attached to the liner, the imagable bodies providing a sharp contrast so as to define a pattern which indicates the prosthesis position when the prosthesis is imaged within the patient body; wherein the imagable bodies are visible through and appear substantially within associated openings of the expanded frame when the expanded prosthesis is imaged within the patient body.

18. A method for fabricating a position indicating endoluminal prosthesis for use in a body lumen of a patient body, the method comprising:
-
affixing a radially expandable frame to a tubular liner so that the frame supports the liner; and attaching a plurality of marker elements to the liner so that the marker elements define a pattern, the marker elements comprising plates of a material capable of producing a sharp contrast when imaged so that the pattern indicates a position of the prosthesis when the prosthesis is imaged within the patient body wherein the expanded frame holds the liner such that the plates do not contact the frame within the body lumen. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26)
