Cleaning Device for Catheter and Catheter Including the Same

摘要

A cleaning device for cleaning a catheter lumen of a tissue removal catheter has a flushing chamber with distal and proximal seals and an inlet port. The proximal seal is a duckbill seal that includes a pair of opposing duckbill members that slidingly accept the distal end portion of a catheter body to form a seal about the catheter body proximal to a proximal opening in of the catheter lumen. Fluid is directed in the inlet port, into the flushing chamber, into proximal opening in the catheter body, and through the catheter lumen to discharge tissue contained in the catheter lumen. In some embodiments, the cleaning device is preloaded on the catheter body. The cleaning device can have an internal stop that engages with an external stop on the catheter body when the cleaning device is positioned in an operative position.

1. A cleaning device for cleaning a catheter comprising a catheter body having a distal end portion defining an catheter lumen and proximal and distal openings in fluid communication with the catheter lumen, the cleaning device comprising:
a flushing chamber having opposite proximal and distal ends, a flushing lumen extending between the proximal and distal ends, and an inlet port in fluid communication with the flushing lumen, wherein the flushing lumen is configured to accept the distal end portion of the catheter body therein through the proximal end thereof; a proximal duckbill seal sealingly received in the flushing lumen at a location proximal to the inlet port, the proximal duckbill seal including a pair of opposing duckbill members configured to slidingly accept therebetween the distal end portion of the catheter body to form a fluid seal about the catheter body proximal to the proximal opening and distal to the proximal opening.
