    摘要： A multilumen catheter that maximizes the blood flow into and out of the patient's vasculature while also providing for passive and/or active perfusion of tissue downstream of where the catheter resides in the vasculature. The inventive catheter comprises a proximal end, a first distal and a second distal end. Lumens extending from the proximal end to each of these distal ends provide for blood circulation within one or between two blood vessels. At least one aperture in one of the lumens positioned near the proximal end provides for active perfusion of blood to the patient's vasculature downstream of where the aperture resides in the vasculature when the catheter is inserted into the patient for treatment. The inventive catheter may comprise a third lumen positioned entirely within the patient's vasculature, providing passive perfusion of blood to the patient's vasculature downstream of where the third lumen resides in the vasculature when the catheter is inserted into the patient for treatment.

    摘要： 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.

    摘要： Catheters including a rugged, reusable proximal body and a disposable distal body attached by a releasable connection are provided. The reusable proximal body is constructed from resterilizable materials such as glass, metal alloys and engineering plastics. The disposable distal body, designed for one-time use, is made from reliable but inexpensive materials. The catheters may be dilatation catheters and may be manufactured in any configuration, including rapid exchange, balloon-on-a-wire, and over-the-wire designs with single or multiple lumens. The modular construction of the catheter and releasable connection provides for rapid and easy changes in the configuration and balloon size depending on the needs of the medical procedure.
