ABSTRACT:
A multilumen vascular catheter (1) having a flexible catheter tube (16) with a distal end-portion (12) which is terminated by a guide-wire opening (26). The catheter tube (16) has a first lumen (18) for extraction of fluid from the vessel (1) and a second lumen (20) for introducing fluid to the blood vessel (14). One or more suction openings (22) communicate with the first lumen (18) and are located upstream of one or more outlet openings (24), which in turn communicate with the second lumen (20). The distal end-portion (12) is permanently bulbous and has a first, widening section (A) starting distally from the catheter tube (16) with a gradually increasing external cross-section to a shoulder (30) with a maximum external diameter into a second, narrowing section (B) having a gradually decreasing external cross-section distally. One or more of the suction openings (22) are located in the first, widening section (A) of the distal end-portion (12) while one or more of the outlet openings (24) are located in the second, narrowing section (B).
