  • Balloon catheter with reinforced and elastically deformable basic body
    Patent number: 5820613
    Abstract: The balloon catheter comprises a tube-like basic body having a distal end-section in which a balloon member is arranged. The inside of the balloon member is connected, via a lumen in the basic body, with a connecting member at the proximal end of the basic body. Via this connecting member and the lumen, liquid or gas under pressure can be supplied to the balloon, in order to expand the latter. The distal end-section is stiff and elastically deformable.

  • 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.
