An extracorporeal vascular conduit for circulating blood outside a patient's body over an extended period of time in a manner that minimizes risk of thrombosis and complement activation and maximizes the ability of a patient to be ambulatory during recovery stages. The inventive vascular conduit comprises a first biocompatible material and a second synthetic material that is employed over a portion of the biocompatible material that extends outside the patient's body when is use. The majority of the portion that extends within the patient's body remains uncoated. A third synthetic material is applied around the conduit near the distal end of the second coating material of the catheter to permit a physician to secure the catheter to the patient's skin to minimize relative movement. |
