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.
