Abstract

Abstract This invention relates to a catheter comprising a tube-like basic body with a distal and a proximal end and at least one lumen. The catheter comprises, connected to the basic body, hardened material in which particulate magnetic material has been received. As a consequence the position of the catheter inside the body of the patient can be made clearly visible on an NMR screen.
