Arteriovenous access for hemodialysis employing a vascular balloon catheter and an improved hybrid endovascular technique

摘要

The present invention provides a kit apparatus and a methodology to prevent the primary causes of arteriovenous graft thrombosis; and provides a durable vascular access for successful long term use in hemodialysis. The invention employs a patient-customized prosthetic endograft as an subcutaneously implanted vascular access; and utilizes a surgical method for endovascular insertion of the prosthetic endograft into a pre-chosen vein, which does not require a distal anastomosis, and thus allows the distal outflow end of the implanted vascular access to remain unattached and freely floating at a precisely located anatomic position within the internal lumen the pre-chosen vein.
