Patent ID: 8303650

Claim:
A biodegradable prosthesis, comprising: a first end, a second end, and an elongate tubular body with a lumen therethrough; a first layer comprising a first bioactive agent; a second layer comprising a set of flexible interbraided bioabsorbable filaments; and a third layer comprising a porous thermoplastic material, 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 to provide enhanced radial support such that the first cross-sectional outer diameter and the second cross-sectional outer diameter are both larger than the third cross-sectional outer diameter while 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 to provide a stable flow path when the prosthesis is placed within the blood vessel, wherein the prosthesis comprises a drug delivery reservoir between the first wall and the second wall, wherein the drug delivery reservoir comprises a second bioactive agent.
