A multilumen catheter for minimizing limb ischemia

A multilumen catheter for directing the flow of blood through a patient through a single cannulation site, said catheter comprising: a catheter (210) having a proximal end (216), a first distal end (218) and a second distal end (220) extending said first distal end (218) distally beyond the proximal end (216) than the second distal end (220); and extending a first lumen (212) between said first distal end (218) and said proximal end (210); a second lumen (214) between said second distal end (220) and said proximal end (216), characterized in that said catheter comprises means for biasing said first distal end (218) towards a J-shape so extending said first lumen (212) is curved at said first distal end (218) such that blood exiting the lumen (212) is directed back along the multilumen catheter (210).
