Реферат: 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).
