    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.

    摘要: A catheter for removing tissue from a body lumen includes a rotatable cutter. The cutter includes an annular cutting edge at the distal end portion of the cutter for removing tissue from the body lumen. An axial cavity is defined by an interior surface of the cutter and extends proximally from the annular cutting edge toward the proximal end portion of the cutter. An eccentric opening extends from the central cavity through the cutter to allow tissue removed from the body lumen by the annular cutting edge to pass proximally through the eccentric opening toward an interior passage of the catheter body. The offset opening is offset from the longitudinal axis of the cutter.

    摘要: A rotatable cutter for a tissue-removing catheter includes a central hub, flutes spaced apart from one another around the circumference of the central hub, and arcuate cutting members. Each cutting member includes an arcuate cutting edge extending along an arc length of the cutting member for cutting tissue as the cutter is rotated. A raised element of each cutting member has a leading cutting edge at a leading end of the distal cutting member for cutting tissue as the cutter is rotated. A clearance portion of each cutting member is recessed, relative to the longitudinal axis of the cutter, from the raised element and extends from the raised element to a trailing end of the cutting member to provide clearance for the leading cutting edge of an adjacent and opposing distal cutting member.
