TIP CONFIGURATIONS FOR MULTI-LUMEN CATHETER

Title:

TIP CONFIGURATIONS FOR MULTI-LUMEN CATHETER

Document Type and Number:

WIPO Patent Application WO2006014339

Kind Code:

A3

Abstract:

Multi-lumen catheters with improved tip configurations, including a triple-lumen catheter which may be useful for apheresis. In one variation, the catheter has three lumens with distal openings angularly spaced apart and staggered axially with respect to one another. In another variation, the catheter has two lumens exiting distally and one centrally positioned lumen exiting proximally. A third variation is a catheter with a single distal opening and two proximal openings. The staggered lumen openings along the axial length of the catheter may decrease recirculation while maximizing flow rates.
