TISSUE-REMOVING CATHETER WITH RECIPROCATING TISSUE-REMOVING HEAD

摘要

A tissue-removing catheter (10) includes a catheter body (12) and a tissue-removing head (14). The catheter body has an annular shearing blade (22) at the distal end thereof. The tissue-removing head is at the distal end of the catheter body and is configured to rotate (D3) about an head axis relative to the catheter body, and reciprocate (D2) along the head axis relative to the catheter body between proximal and distal positions.
