Abstract
A temporary bioabsorbable-radiopaque marker for use on an implantable endoprosthesis. The bioabsorbable-radiopaque marker is adapted to be disposed on or adjacent an implantable endoprosthesis in a body lumen for a predetermined amount of time until the bioabsorbable and radiopaque materials are absorbed or dispersed in the body.
Claims39
1-27 (Canceled)
(New) An implantable prosthesis and bioabsorbable radiopaque marker system comprising:
- an implantable, tubular, axially flexible prosthesis including a plurality of elongate filaments interwoven in a braided configuration, adapted for delivery to a treatment site in a body lumen;
- and
- a radiopaque marker comprising a bioabsorbable material and a radiopaque material and adapted to degrade in vivo whereby the bioabsorbable material is capable of being metabolized through the body, and the radiopaque material is excreted from or stored in the body;
- and
- wherein the radiopaque marker is more radiopaque than the prosthesis, and is secured with respect to the prosthesis in a manner to enable locating the prosthesis in vivo by fluoroscopically imaging the marker.

(New) An implantable endoprosthesis and bioabsorbable-radiopaque marker system comprising:
- an implantable prosthesis adapted to be disposed in a body lumen;
- and
- an elongated marker adapted to be secured with respect to the prosthesis in a manner to enable locating the prosthesis in vivo by fluoroscopically imaging the marker, said marker comprising a bioabsorbable material and a radiopaque material, the marker having at least one cavity with the radiopaque material disposed therein and wherein the bioabsorbable material at least partially contains the radiopaque material, wherein the marker is more radiopaque than the prosthesis.
(New) An implantable medical device, including:
- a tubular, radially expandable prosthesis adapted for deployment in vivo;
- and
- a discrete marker including a dispersible radiopaque material and thereby being more radiopaque than the prosthesis, and further including a bioabsorbable material whereby the marker is degradable in vivo;
- wherein the discrete marker is secured to the prosthesis at a predetermined portion of the prosthesis to provide an enhanced radiopacity over said predetermined portion, thus to facilitate a selective positioning of the prosthesis in vivo through a fluoroscopic imaging of the marker;
- and
- wherein the discrete marker tends to degrade in vivo at a first degradation rate, thus to diminish the radiopacity over said predetermined portion after deployment.
