Patent ID: 8062247

Claim:
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 wall forming a blood feeding lumen and a blood removal lumen, and an internal arcuate wall defining a transfusion lumen protruding from an inner wall of the blood removal lumen, the internal arcuate wall being spaced from the internal partition wall, the catheter body having a blood feeding port at 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, the catheter body including an oblique surface adjacent the leading end, the oblique surface at least partially defining the blood feeding port; and a leading member mounted to the leading end of the catheter body and including a tail portion positionable within the blood removal lumen such that the blood feeding port is unobstructed by the leading member, the leading member 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.
