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.

摘要： A tissue-removing catheter includes a tissue-removing element operably connected to a drive shaft for rotation of the tissue-removing element about an axis of rotation in a cutting direction. The tissue-removing element is, in some embodiments, an integrally formed one-piece body. The tissue-removing element has a tissue-removing head that includes a plurality of shearing members spaced apart around the axis of rotation. Channels separate the plurality of shearing members and extend through the radially outer surface of the tissue-removing head. In some embodiments, the shearing members include respective wedge portions that hook and cleave tissue as the tissue-removing element rotates.

摘要： A cleaning device for cleaning a medical instrument. First and second body portions in a closed position define a flushing chamber. The medical instrument extends through the flushing chamber. First and second sealing members secured to the first and second body portions engage one another to seal the flushing chamber and engage the medical instrument to form a seal thereabout. Portions of at least the first sealing member are disposed within the flushing chamber. Positive pressure in the flushing chamber urges the first sealing member toward the second and toward the medical instrument to enhance the tightness of the flushing chamber seal.

摘要： A tissue-removing catheter includes a tissue-removing element operatively connected to a drive shaft for rotation of the tissue-removing element about an axis of rotation in a cutting direction. In some embodiments, the tissue removing element has a cutting blade and cutting teeth positioned radially inward of the cutting blade with respect to the axis of rotation. The cutting blade and cutting teeth are fixed with respect to one another to form first and second cuts in tissue as the tissue-removing element rotates. In certain embodiments, the tissue-removing element includes a cutting blade and raised elements spaced apart inward of the cutting blade relative to the axis of rotation to define an annular tissue-receiving channel between the cutting blade and the raised elements. A bottom surface of the channel can define cutting teeth.
