A balloon catheter for use in the region of a vessel branching and, in particular, in coronary vessels is provided. The catheter comprising a catheter stem disposed at the distal end of which are provided at least one balloon and at least one first guide means arranged in the region thereof for positioning the balloon in the region of a vessel branching. The first guide means is adapted to be introduced into the lateral branch of the vessel transversely with respect to the longitudinal direction of the balloon catheter. The balloon comprises at least two chambers which are spaced from each other in the longitudinal direction of the balloon catheter and between which the first guide means is arranged.

Balloon catheter

The invention concerns a balloon catheter (,) for dilating vascular constrictions and for simultaneously introducing a permanently deformable stent (,) into the vessel to be dilated in order to stabilize it in the dilated condition, wherein the distal region of the catheter which is intended to receive the stent has an inner tube (,) which is surrounded by the non-expanded stent, the balloon (,) is arranged between the stent (,) and the inner tube (,) and the inner tube has at its ends as X-ray markings two sleeves (,) which are carried thereon and which comprise an X-ray-opaque material and which are provided within the balloon on the inner tube, wherein provided between the inner tube and the outer balloon is a tube (,) which forms an additional plateau and which comprises a soft-elastic material as an intermediate layer, in such a way that it extends in the longitudinal direction to beyond the sleeves forming the X-ray markings.
