Catheter

Abstract

Abstract In a catheter (10), two lumina (13, 14) lying alongside one another in a catheter tube (11) are separated from one another by a longitudinally extending septum (12). In this case, the first lumen (13) has at the tip of the catheter tube (11) an end opening (20) (expulsion opening), and axially consecutive lateral openings (22, 23) (suction openings) of the second lumen (14) are displaced into different planes by permanent deformation of the catheter tube (11). In this way, it is possible to eliminate the risk of simultaneous occlusion of all the suction openings as a result of bearing on the vessel wall. The catheter tube (11) in the area of the lateral openings (22, 23) of the second lumen (14) is preferably twisted about its longitudinal axis by at least 90 DEG . <IMAGE>
