Abstract
Abstract A device for endoluminally placing an endovascular tubular prosthesis in a vascular duct along a guide wire. The device comprises an introducer exterior sheath and an interior sheath therein, with the prosthesis positioned between the sheaths and an elastic expander compressed inside the interior sheath. The expander furthest end exteriorly projects from the interior sheath and is joined to the tubular prosthesis furthest end. A pusher is linked to the expander nearest end, and may contain a radiopaque substance where it connects to the expander. The expander may have an expanded length that is longer than the length of the prosthesis.

A device adapted to endoluminally place an endovascular tubular prosthesis inside a vascular duct via a guiding wire, the prosthesis having flexible walls and a furthest end, the device comprising: an introducer exterior sheath and an interior sheath therein, said prosthesis positioned between said sheaths; an elastic expander compressed inside said interior sheath, said expander having a nearest end and a furthest end, said expander furthest end exteriorly projected from said interior sheath and joined to said tubular prosthesis furthest end.
Claim 3
Dependent Claim
19 words
The device according to claim 1, wherein the expander nearest end links to a connection end of a pusher.
Claim 4
Dependent Claim
14 words
The device according to claim 2, wherein the connection end contains a radiopaque substance.
Claim 5
Dependent Claim
42 words
