Cleaning device for catheter and catheter including the same
First Claim
1. A cleaning device for cleaning a catheter comprising a catheter body having a distal end portion defining a 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 of 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 proximal fluid seal about the catheter body at a location proximal of the inlet port; and
a distal duckbill seal sealingly received in the flushing lumen at a location distal of the inlet port such that the inlet port is located between the proximal duckbill seal and the distal duckbill seal, the distal duckbill seal being configured to form a distal fluid seal about the catheter body, the distal duckbill seal including a pair of opposing duckbill members configured to slidingly accept therebetween the distal end portion of the catheter body to form the distal fluid seal about the catheter body;
wherein each of the proximal fluid seal and the distal fluid seal is configured to prevent fluid in the flushing lumen from passing therethrough,wherein the pair of opposing duckbill members defines a tapered distal end of the proximal duckbill seal,wherein the pair of opposing duckbill members of the distal duckbill seal defines a tapered proximal end of the distal duckbill seal.

Abstract
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.
