  • Publication number: 20150057690
    Abstract: A method of removing material from a blood flow lumen includes providing a device having a cutting element and an opening, the cutting element being movable relative to the opening. The method then includes advancing the device through a patient's vascular system to the blood flow lumen. Finally, the method involves moving the cutting element and the opening relative to the blood flow lumen so that a continuous piece of material is severed by the cutting element and directed into the opening as the cutting element and opening move through the blood flow lumen, the continuous piece of severed material being directed into the device for removal from the patient. The method may include providing a device having a rotatable cutter that, in some embodiments, is not parallel to the longitudinal axis of the device, is movable, has retracted and deployed positions, or any combination thereof.

  • Patent number: 8961546
    Abstract: A device for re-entering a lumen during an endovascular procedure when in a subintimal space includes a rotating cutter extending within a first lumen used for cutting tissue, and an energy emitter which emits energy through a window to locate a lumen when in a subintimal space adjacent to the lumen. The cutter is movable to a cutting position which exposes part of the cutter through a first opening so that the cutter may create a path from the subintimal space to the lumen. The cutter is movable distally relative to the elongate body to move the cutter to the cutting position and deflect the distal body portion relative to the main body portion.

  • Publication number: 20140163591
    Abstract: A method of removing material from a blood flow lumen generally includes providing a device having a cutting element and an opening, advancing the device through the blood flow lumen to a site where material is to be removed, forcing the opening toward a wall of the site where material is to be removed, and moving the cutting element and the opening so that material in the blood flow lumen is cut by the cutting element and directed into the opening for removal as the cutting element and opening are moved through the blood flow lumen. In some embodiments, the device may be deflected or bent to force the opening toward a wall to remove material. The cutting element may be rotatable and may have an axis that is movable, that is not parallel to the longitudinal axis of the device, or both.

  • Publication number: 20120209112
    Abstract: A rotating cutting head catheter for passage through chronic total occlusions or other refractory atherosclerotic plaque from diseased arteries is disclosed. The catheter's rotating cutting head is designed to reside safely within an outer protective sheath when not in use. The outer protective sheath contains one or more helical grooves or slots, and the cutting head contains protruding blades or projections that fit into these helical grooves or slots. Application of torque to an inner catheter or wire attached to the cutting head applies spin to the cutting head, and the force of the sheath's helical grooves or slots against the cutting head's protruding blades or projections advances the cutting head outward from the protective sheath. Once extended, the cutting head may now rotate freely. The device may use a guidewire to direct the cutting head to the desired position.
