摘要

Medical catheter for supplying a self-expanding, not - precharged stents into a body lumen with at least two working fluid ducts (10, 11) and a balloon (12), which in the distal region of the working fluid ducts (10, 11) is arranged, wherein a first working channel (10) with the balloon (12) is in fluidic connection and a second working channel (11) extending through the balloon (12), wherein the second working channel (11) a distal outlet opening (13) for the functional element and with a proximal arranged, in the use of extracorporeal connection which is connected to the introduction of the functional element in the second working channel (11) is adapted, and wherein the inner diameter of the second working channel (11) of less than 0,45 mm, characterized in that at least one x-ray marker (18, 19, 20) is provided, wherein a first x-ray marker (18) in the region of the distal outlet opening (13) of the second working channel (11), a second x-ray marker (19) in the region of the distal balloon end (15) and a third x-ray marker (20) in the region of the proximal balloon end (17) are arranged.
