摘要： A catheter may include an elongate body extending from a proximal end to a distal end and defining a lumen; a push member mechanically coupled to the proximal end of the elongate body; and a slidable push grip disposed about an outer perimeter of the push member. The slidable push grip is controllably engageable with the push member. When the slidable push grip is in an engaged state with the push member, the slidable push grip transmits an axial force to the push member to enable the push member to transmit the axial force to the elongate body. When the slidable push grip is in a disengaged state with the push member, the slidable push grip is movable axially in at least one direction along a length of the push member while transmitting substantially no axial force to the push member.

摘要： A catheter may include an elongate body including a proximal portion including a proximal end, and a distal tip portion. The distal tip portion may include an inner liner and a marker band circumferentially surrounding the inner liner. The distal tip portion also may include an outer jacket circumferentially surrounding a first portion of the inner liner and ending proximal of a proximal end of the marker band; and a tip outer jacket circumferentially surrounding a second portion of the inner liner and the marker band. The tip outer jacket extends distally past the marker band distal end to a distal tip of the elongate body, and a proximal end of the tip outer jacket may be laterally adjacent to a distal end of the outer jacket.

摘要： A tissue-removing catheter for removing tissue in a body lumen includes a catheter body assembly having an axis and proximal and distal end portions spaced apart from one another along the axis. At least a portion of the catheter body assembly is sized and shaped to be received in the body lumen. A handle is mounted to the proximal end portion of the catheter body assembly and operable to cause rotation of the catheter body assembly. The handle includes internal handle components that interface with the catheter body assembly. The internal handle components provide at least four interface locations spaced axially along the catheter body assembly. A tissue-removing element is mounted on the distal end portion of the catheter body assembly. The tissue-removing element is configured to remove the tissue as the tissue-removing element is rotated by the catheter body assembly within the body lumen.
