  • Two balloon catheter
    Patent number: 5733299
    Abstract: The catheter comprises: a tube-like basic body having a distal end, a distal end section, a proximal end and two balloons mounted to the distal end section. One of the balloons is a dilatation balloon and the other of the balloons is used for the purpose of carrying and expanding a stent. Also, one of the two balloons is more pliable than the other of the two balloons. The balloons possess varying degrees of pliability. The different degrees of pliability can be a result of the fact that the wall thickness of the balloons varies.
