ABSTRACT:
An implantable prosthetic device for sustained release of a bioactive material into a fluid flow pathway of a patient comprises a body adapted for attachment to the fluid flow pathway. The body defines a primary lumen for accommodating fluid flow therethrough and at least one secondary lumen at least a portion of which is separated from the primary lumen by a wall sufficiently permeable to permit a bioactive material disposed in the lumen to diffuse through the wall and into the primary lumen. The bioactive material can be either a therapeutic or diagnostic agent. In a particular embodiment of the invention, the device comprises a tubular body consisting of stretched and/or expanded polytetrafluoroethylene and is adapted for attachment to a blood vessel of a patient.
