Abstract:
Medical devices and methods for forming an arteriovenous (AV) fistula include a stent having an arterial tubular portion and vein supporting tongue connected by a pre-shaped connector and a venous frustoconical stent having a distal end for maintaining a take-off angle for the venous portion of the AV fistula. Also disclosed is an angled balloon for assisting with the formation of the AV fistula. The medical devices disclosed herein support an AV fistula formation having a desired take off angle of about 30 degrees, or between about 15 and 45 degrees.

Abstract:
This invention relates to an method of manufacture of an implantable medical device comprising an oxygen-sensitive rapamycin derivative that is protected by addition of an antioxidant during the manufacturing process where the amount of antioxidant added at the outset of the processing is such that when the device is fully fabricated, sterilized and packaged the amount of antioxidant has reduced to a minimal, preferably non-detect, amount.
