摘要：
An atherectomy catheter includes an elongate catheter body, a cutter at a distal end of the catheter body, and a nosecone attached to a distal end of the catheter body. The cutter is configured to excise tissue from the body. The nosecone is configured to hold tissue excised from the cutter. The nosecone includes a distal section, a proximal section, and a connection mechanism that is configured to allow the distal section to attach and detach from the proximal section during use. The distal section includes a plug configured to sit within an inner diameter of the proximal section when the proximal section is connected to the distal section.
