Abstract
A catheter adapted to be inserted into and advanced through a patient's circulatory system or through any other hollow conduit of the body is disclosed. The catheter of the present invention comprises a shunt section incorporating an elongated conduit having an open, distal end and a closure intermediate the open distal end and the outer terminal end of the catheter. A first inflatable cuff is located at the distal end of the tube while a second cuff is located at a predetermined distance from the first cuff, between the distal end and the closure of the shunt section. A pair of radiographic markers assist in the proper positioning of the cuffs. Means are provided to allow the blood to exit the tube near the proximal end thereof. Inflating and deflating means for the cuffs are also provided.
