ABSTRACT:
Disclosed is an improved balloon catheter having a three-layer balloon tube fixed to and enclosing an apertured end of an elongated flexible fine tube. The three-layer composite balloon tube is composed of inner and outer rubber tubes and an intervenient cloth bag, which is effective to hold the shape and size of the expanding balloon appropriately for the purpose and to raise and keep the inner-pressure of the expanding balloon at an elevated value without any fear for rupturing a hollow organ of a human body. A pair of rubber bands are dispersed about portions of the balloon to initially restrict expansion of said portions at a stenosis of the hollow organ.
