A device for cutting venous valves comprises a support member (1), adapted to be inserted into a vein and having a fore, rounded insertion end (2) and a rear end provided with cutting means (3), the cutting means (3) having a cutting edge or edges extending substantially transversely to the member (1) and being directed in the backward direction of the support member to cut venous valves when the support member (1) is moved in said direction. A possibly branched fluid duct (4) extends from an inlet (5) centrally disposed at the rear end of the support member (1) to at least one outlet (7) located ahead of the cutting means (3), and the inlet (5) is connected or connectable to a fluid supply means (8) through an at least slightly flexible conduit (6). |
