ABSTRACT:
An implantable flow restrictor plug is disclosed that is disposed within a deployed endoluminal prosthesis to initially restrict, then gradually restore blood flow through the prosthesis after an angioplasty procedure. Upon initial deployment, the plug has a tubular biodegradable body defining a blood flow lumen therethrough that is sized to effectively reduce the amount of blood flow exiting the prosthesis. An inner surface of the body erodes or biodegrades in vivo to enlarge the plug lumen, thereby gradually restoring blood flow through the prosthesis until blood flow is unimpeded through the prosthesis, i.e., blood flow through the vessel is fully restored. The flow restrictor plug may be attached to the endoluminal prosthesis to be delivered and deployed therewith, or may be formed within a previously deployed prosthesis.
