A catheter assembly for use in the extracorporeal treatment of bodily fluids. The assembly comprises a catheter body having a withdrawal port, an infusion port, and a plurality of lumens therein. One of the lumens comprises a withdrawal lumen for transport of fluids withdrawn from a body vessel through the withdrawal port to an extracorporeal treatment unit, such as a dialyzer. Another lumen comprises an infusion lumen for return of treated fluids from the extracorporeal treatment unit into the body vessel through the infusion port. A wire extends from yet another lumen to an attachment point on the catheter assembly. The wire is capable of bowing radially outwardly from the catheter body, in order to space the infusion and withdrawal ports from the vessel wall. |
