WINGED CATHETER ASSEMBLY
First Claim
1. A catheter assembly, comprising:
- a catheter body having a plurality of lumens extending therein, said catheter body having an aspiration port in communication with a first lumen for transporting fluid withdrawn from a body vessel, and an infusion port in communication with a second lumen for return of fluid to said vessel;
said catheter body comprising a flap portion extending radially from said catheter body and defining said aspiration port, said flap portion configured and arranged to space said aspiration port from a wall of said body vessel.

Abstract
A catheter assembly for use in extracorporeal treatment of a body fluid comprises a catheter body having a plurality of lumens extending therein. The catheter body has an aspiration port in communication with a first lumen for transporting fluid withdrawn from a body vessel to a treatment instrument, such as a dialyzer, and an infusion port in communication with a second lumen for return of treated fluid to the vessel. The catheter body includes a wing-like flap portion extending radially from the catheter body and defining the aspiration port. The flap portion is configured and arranged to space the aspiration port from a wall of the body vessel.

13. A catheter assembly for use in the extracorporeal treatment of a body fluid of a patient, comprising:
an elongated catheter body having a proximal end, a distal end, a pair of lumens extending at least substantially therethrough, and a septum separating said lumens, one of said lumens comprising an aspiration lumen, and the other of said lumens comprising an infusion lumen, an aspiration port disposed along a length of said catheter body in communication with said aspiration lumen for receiving body fluid from a body vessel of said patient for transport to a treatment unit, and an infusion port in communication with said infusion lumen for returning treated body fluid to said vessel, said catheter body comprising a flap portion extending radially therefrom and defining said aspiration port, said flap portion being structured to substantially maintain said radial extension from said catheter body when inserted into said body vessel and engaging a wall of said vessel, said aspiration port disposed proximal to said infusion port along said catheter body length. - View Dependent Claims (14, 15)

16. A method for treating a body fluid, comprising:
-
providing an assembly for transporting said body fluid, said assembly comprising a catheter body having a plurality of lumens extending therein, said catheter body having an aspiration port in communication with a first lumen for transporting fluid withdrawn from a body vessel, and an infusion port in communication with a second lumen for returning fluid to said vessel, said catheter body comprising a flap extending radially from said catheter body and defining said aspiration port, said flap being structured to substantially maintain said radial extension from said catheter body when inserted into said body vessel and engaging a wall of said vessel; inserting a distal end of said assembly into said vessel; aspirating body fluid to be treated from said vessel through said aspiration port; transporting said aspirated fluid through said first lumen to a treatment instrument; treating said fluid in said treatment instrument; transporting said treated fluid from said treatment instrument through said second lumen; and infusing treated fluid into said body vessel through said infusion port. - View Dependent Claims (17, 18, 19, 20)
