A tissue-removing catheter for removing tissue in a body lumen includes an elongate body having an axis. A handle is mounted to a proximal end portion of the elongate body. A tissue-removing element is mounted on a distal end portion of the elongate body. An inner liner is received within the elongate body and defines a guidewire lumen. An advancer is mounted on the handle and is movable relative to the housing. The inner liner is coupled to the advancer at a proximal end portion of the inner liner such that movement of the advancer causes a corresponding movement of the inner liner to exert a push force on the tissue-removing element to advance the tissue-removing element and a pull force on the tissue-removing element to retract the tissue-removing element for moving the tissue-removing element relative to the handle.

Tissue-removing catheter with a coupled inner liner

The present disclosure provides a tissue-removing catheter for removing tissue in a body lumen that includes an elongate body, a handle, tissue-removing element, liner assembly, and coupling assembly. The elongate body is sized and shaped to be received in the body lumen. The tissue-removing element is mounted on a distal end portion of the elongate body and removes tissue as rotated by the elongate body. The liner assembly defines a guidewire lumen. The coupling assembly is coupled to the liner assembly with a first orientation and a second orientation relative to the coupling assembly. The first orientation permits distal movement of the liner assembly relative to the coupling assembly prior to rotation of the elongate body to rotate the tissue-removing element. The second orientation is relative to the coupling assembly after rotation of the elongate body to prevent distal movement of the liner assembly relative to the coupling assembly.

A package includes a tray and a cover configured to seal an open end of the tray when the cover is assembled onto the tray. The tray has a flange extending about a periphery at the open end of the tray. A continuous barrier seal is formed between the flange and the cover when the cover is assembled onto the tray, and a discontinuous sacrificial seal is also formed between the flange and the cover when the cover is assembled onto the tray. The discontinuous sacrificial seal is configured to absorb stress applied to the flange. The continuous barrier seal is disposed closer to an inner periphery of the flange than the discontinuous sacrificial seal. Holes are formed on the corners of the flange, and the holes are spaced apart from the discontinuous sacrificial seal.
