摘要：
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.
