Patent ID: 7553325

Claim:
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, wherein the elongate filaments form multiple crossing points, 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 surrounding relation to a pair of the elongate filaments at one of the crossing points and in a manner to enable locating the prosthesis in vivo by fluoroscopically imaging the marker.
