Abstract

A signal lead for an electromagnetic localization marker, which is coupled to a prosthesis, is releasably coupled to the prosthesis. In one embodiment, the lead and electromagnetic localization marker are both releasably attached to the prosthesis through a coupling. In another embodiment, a portion of the lead adjacent to the electromagnetic localization marker is electrolytically dissolved in vivo and the lead removed.

Claims

1. Tubular prosthesis apparatus comprising:

a tubular member having a proximal end portion and a distal end portion and being adapted for endovascular delivery to a site in a patient; and

an electromagnetic localization marker and signal lead, said signal lead being electrically coupled to said electromagnetic localization marker and releasably coupled to said proximal end portion of said tubular member.

2. The prosthesis apparatus of claim 1 wherein said tubular member has a pocket and said electromagnetic localization marker is releasably retained in said pocket.

3. The prosthesis apparatus of claim 2 wherein said tubular member is a stent-graft.

4. The prosthesis apparatus of claim 1 wherein said lead has an electrolytically disintegratable link adjacent to said electromagnetic localization marker.

5. The prosthesis apparatus of claim 4 further including insulation surrounding said lead proximal to said link and insulation surrounding said electromagnetic localization marker.

6. The prosthesis apparatus of claim 5 wherein said prosthesis is a stent-graft.

7. The prosthesis apparatus of claim 1 wherein said prosthesis is a stent-graft.
