1. A balloon catheter for dilating vascular constrictions and for simultaneously introducing a deformable stent into a vessel to be dilated in order to stabilize the vessel in the dilated condition, wherein a distal region of the catheter, which is intended to receive the deformable stent, comprises:

  • an inner tube that is surrounded and crimped onto by the deformable stent;

    a balloon arranged between the deformable stent and the inner tube;

    a pair of longitudinally spaced image sensitive marking sleeves carried on the inner tube within the balloon such that there is a longitudinal space on the inner tube extending between the pair of marking sleeves and such that the deformable stent is substantially centered there-between;

    an outer tube disposed between the inner tube and the balloon as an intermediate layer, wherein the intermediate layer substantially covers the longitudinal space on the inner tube between the image sensitive marking sleeves, the intermediate layer having an outer diameter, wherein the outer diameter of the intermediate layer is substantially constant between the pair of marking sleeves.
