Abstract

The present application concerns a double-lumen catheter, an elongated tubular body (11) having a proximal end and distal end, a divider wall (26) extending along an interior of said tubular body (11) and separating said interior into an intake lumen (22) and a return lumen (24), and the intake lumen (22) and said return lumen (24) each comprising a bevelled opening (12; 14) sloping toward the divider wall (26) and toward the distal end of the tubular body (11), respectively, the openings (12; 14) being divided by the divider wall (26), such, that one side of the divider wall (26) faces the intake lumen (22) and the other side of the divider wall (26) faces the return lumen (24). Further, the divider wall (26) at the distal end of the tubular body (11) on at least one of its two sides comprises at least one ridge (16; 18) extending in the area of the openings (12; 14) and along a longitudinal portion of the tubular body (11).

Description

technical field [0001] The present invention relates to dual lumen catheters for delivering or withdrawing fluids from a patient. The catheter includes an elongated tubular body having a proximal end and a distal end, the distal end being positioned within a vessel of the patient, a dividing wall extending along the interior of the tubular body and dividing the interior into an inflow lumen and a backflow lumen lumen, the inflow lumen and the return lumen each extend from the proximal end to the distal end of the tubular body, the inflow lumen and the return lumen are defined by the outer wall and the partition wall, and the inflow lumen and the reflux lumen each include oblique openings inclined toward the partition wall and toward the distal end of the tubular body, the openings are separated by the partition wall so that one side of the partition wall faces the inflow chamber while the other side of the partition wall faces the return chamber. Background technique [00...
