In order to create a catheter that is not only easy to manufacture and handle, but also enables a perfect and complete removal of inclusions in a manner that is safe for the patient, the invention proposes that at the front end of the tubular body (1 ) there is an expansion head (2) which has one or more peeling knives (6) made of highly elastic material, which or which can be arched out by means of a tensioning wire (7) or the like running in the tubular body (1) and at the rear End (10) of the tubular body (1) has a handle (5). In order to ensure that vascular walls not affected by calcification cannot come into contact with the rotating peeling blades, it is further proposed that the expansion head (2) be equipped with an approximately band-shaped protective shield made of highly elastic material, which extends over part of the circumference of the expansion head extends. To largely avoid blood loss, it is further proposed that on the tubular body (1) in its area in front of the peeling knives (6) and / or on the tension wire (7) in its area between the two parts of the split tip (3) of the Spreading head (2) is or are attached a piece of hose made of elastic material, in whose or their overlap areas one or more outlet openings of channels open, which penetrate the walls of the tubular body (1) and / or the tensioning wire (7) in their longitudinal direction. |
