  • Patent number: 7468052
    Abstract: An improved method and devices for preventing restenosis are provided. The method may include delivering a stent configured to contain a stenosis to a body vessel. The method may also include using atherectomy at the site prior to stent delivery. In one embodiment, the stent has a proximal end, a distal end, and a center portion arranged such that the diameters of the proximal and distal ends are greater than the diameter of the center portion. In one embodiment, the atherectomy device includes a housing to prevent injury to the unaffected areas of the body vessels but the cutter is extendible beyond the housing. In one embodiment, the stent may be impregnated with at least one drug after stent deployment.

  • Patent number: 6015402
    Abstract: A low profile wire perfusion catheter is disclosed for use in percutaneous transluminal coronary angioplasty. The catheter includes a wire configured to be inserted into a blood vessel. The wire is hollow and defines an axial lumen therein. An inflation balloon is attached directly to the wire and is configured to expand radially outward in response to inflation thereof. Inflow and outflow perfusion ports extend through the wire and communicate with the lumen to allow perfusion of blood across the balloon when the balloon is inflated within a blood vessel. Because the balloon is attached directly to the wire, the catheter has an advantageously low cross-sectional area.

  • Patent number: 5417653
    Abstract: Disclosed is a light angioplasty catheter and method for exposing the interior of a body lumen to a source of light. Light exposure may be accomplished prior to, during, or following conventional balloon dilatation. Also disclosed is a method and apparatus for exposing a preselected portion of vessel wall to a source of light. Relatively low energy light exposure has been found by the inventors herein to both inhibit restenosis following dilatation of a stenotic region, and to inhibit vascular spasms whether or not associated with a stenotic region. It may also arrest progress of a stenosis. Methods are also disclosed for cooling the vascular wall to treat a stenosis. Cooling may be accomplished prior to, during, or following dilatation.
