US 2009/0024084 A1 · MULTI-LUMEN CATHETER ASSEMBLY AND METHOD OF PROVIDING RELATIVE MOTION THERETO

Abstract

A handle for providing relative motion to a multi-lumen catheter assembly includes an elongated handle body having a longitudinal axis. The handle body has longitudinally spaced proximal and distal handle ends. An outer catheter chuck is connected to the distal handle end and is adapted to receive an outer catheter member. An inner catheter chuck is connected to the proximal handle end and is adapted to receive an inner catheter member. A handle actuator is movably connected to the handle body. The handle actuator is adapted to receive an intermediate catheter member and to move the intermediate catheter member relative to the inner and outer catheter members. The intermediate catheter is at least partially interposed between the inner and outer catheter.

A multi-lumen catheter assembly, comprising:

an outer catheter member having a longitudinal axis and longitudinally spaced proximal and distal outer catheter ends with a first lumen defined therebetween;
an intermediate catheter member having longitudinally spaced proximal and distal intermediate catheter ends with a second lumen defined therebetween, the intermediate catheter member being at least partially located within the first lumen;
