Triple lumen catheter

A triple lumen catheter, which comprises:

• a catheter body defining a longitudinal axis and having a proximal trailing end and a distal leading end, the catheter body having an internal partition wail forming a blood feeding lumen and a blood removal lumen, and an internal arcuate wall defining a transfusion lumen, the catheter body having a blood feeding port adjacent the leading end in fluid communication with the blood feeding lumen and a blood removal port proximal of the leading end in fluid communication with the blood removal lumen;
• and
• a leading member mounted to the leading end of the catheter body and having a transfusion channel in fluid communication with the transfusion lumen of the catheter body and terminating in a transfusion port remote from the catheter body, the leading member defining a cross-section transverse to the longitudinal axis reducing in dimension towards the transfusion port.

A triple lumen catheter, which comprises:

• a catheter body defining a longitudinal axis and having proximal and distal ends, the catheter body having an internal partition wall forming a blood feeding lumen and a blood removal lumen, and an internal arcuate wall defining a third lumen, the catheter body having a blood feeding port in fluid communication with the blood feeding lumen and a blood removal port proximal of the blood feeding port in fluid communication with the blood removal lumen, and further having a leading end portion adjacent the distal end and defining a third axial port in fluid communication with the third lumen and being distal of the blood feeding port and the blood removal port, the leading end portion defining a cross-sectional dimension transverse to the longitudinal axis decreasing toward the third axial port.
