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.

摘要： In some examples, a medical device includes an elongated body having an elongated body proximal end and a hub attached to the elongated body proximal end. The hub is configured to provide a removable attachment to an object, such as a surgical drape within a sterile field boundary. In some examples, the attachment mechanism comprises a resiliently biased first elongate arm and second elongate arm configured to establish a clamping action on the object and/or configured to establish a snap fit with each other while the objection is positioned between the first and second elongate arms. In some examples, the attachment mechanism may comprise a surface of the hub configured to provide a traction force on the object to hold the hub in place relative to the object.

摘要： In some examples, a catheter may include an elongate body and a push assembly. The elongate body may include an inner liner defining an entry port into a lumen defined by the elongate body, and an outer jacket. The push assembly may an anchor member positioned at a distal end of an elongate member. Distal to a proximal end of the elongate body, a first portion of the push assembly, comprising the anchor member, may be positioned between a portion of the inner liner and a portion of the outer jacket. The anchor member may extend only partially around an outer perimeter of the inner liner when the catheter is assembled. Proximal to the proximal end of the elongate body, a second portion of the push assembly, proximal to the first portion, may be positioned outside of the outer jacket and the inner liner.
