Abstract

A catheter (1) is rotationally symmetrical at its distal end (3) and has a lateral opening (2). The object of the invention is to design a catheter that minimises thrombus formation. For that purpose, the lateral opening (2) has a valve (2) which closes in the event of an outer overpressure.
