Abstract
An atherectomy device for removing deposits such as plaque from an interior of a vessel including an outer member, an inner member and a rotatable shaft positioned for rotational movement within the inner member. The outer and inner members are fixed axially. A rotatable tip is mounted to the distal region of the rotatable shaft for rotation about its longitudinal axis upon rotation of the shaft to remove deposits from the vessel.
Claims19
An atherectomy device for removing deposits such as plaque from an interior of a vessel comprising:
- a housing;
- an outer member extending from the housing and having a distal end, a first lumen terminating proximal of the distal end of the outer member and a side opening communicating with the first lumen for fluid infusion;
- an inner member having a distal end and positioned within the first lumen of the outer member, the inner member having a second lumen terminating at the distal end of the inner member and having an opening for aspiration of particles proximally within the second lumen, the side opening in the outer member communicating with the second lumen for fluid infusion from the first lumen into the second lumen;
- a rotatable shaft positioned for rotational movement within the second lumen of the inner member;
- and
- a rotatable tip positioned at the distal region of the rotatable shaft and spaced distally from the distal end of the inner member, the rotatable tip rotatable by a motor to remove the deposits from the vessel for aspiration through the second lumen of the inner member;
- wherein the outer member has an end wall to terminate the first lumen proximal of the distal end of the outer member to terminate distal flow of fluid for redirection through the side opening into the second lumen of the inner member.
