Abstract
The catheter is a catheter for controlling the circulation of fluid through it, from or to a vessel in which the catheter is inserted. The catheter comprises a long tubular body that is open especially at its distal end (5), over which there is arranged a cap (5) having an essentially flat distal wall (7) in which there is formed at least one slit forming a valve (7). The slit in the cap has a length that is greater than or equal to the inside diameter of the body of the catheter. The said slit preferably extends also into the side of the cap, and a tube is inserted into the distal portion of the catheter in order to support the sleeve during aspiration.
