Abstract
A balloon catheter is formed by blow molding an elongated polyurethane tube so that one section of the tube has a thinned cross sectional balloon area between the distal end of tube which is sealed and its open proximal end. The balloon portion which is positioned adjacent the distal end has a thinner cross sectional area which allows a balloon to be formed if a fluid is introduced into the catheter by a syringe apparatus which is adapted to be attached to the lumen by a connection adaptor. A wire guide member is adapted to be inserted through the lumen for stretching the catheter when it is inserted into a blood vessel to stiffen the catheter and position it in a proper position. The wire guide member may also be mitred at predetermined intervals to determine the position of the catheter within the blood vessel.
