Patent ID: 8317857

Claim:
An intraluminal prosthesis, comprising: a first end, a second end, and an elongate tubular body with a lumen therethrough; a first layer comprising flexible interbraided filaments, wherein a first group of filaments comprise a biodegradable material and a second group of filaments comprise a metallic material; a second layer of a porous thermoplastic material operably attached to the first layer; and a third layer comprising a first bioactive agent, wherein the prosthesis has a first cross-sectional outer diameter at the first end, a second cross-sectional outer diameter at the second end, and a third cross-sectional outer diameter at a mid-point on the prosthesis axially displaced from the first end and the second end of the prosthesis, wherein the prosthesis is configured such that the first end and the second end both comprise a first wall, wherein a portion of the first wall is folded over to form a second wall, wherein the second wall is secured to the first wall, wherein the first cross-sectional outer diameter and the second cross-sectional outer diameter are both larger than the third cross-sectional outer diameter when the prosthesis is in a first, radially compressed configuration for delivery as well as when the prosthesis is in a second, radially enlarged configuration within a blood vessel, wherein the prosthesis has a continuous, cylindrical cross-sectional inner diameter throughout its axial length, wherein the prosthesis comprises a bioactive agent reservoir between the first wall and the second wall, wherein the bioactive agent reservoir comprises a second bioactive agent.
