  • Patent number: 6796989
    Abstract: An intraluminal cutter having an expandable, rotary cutter with a plurality of cutting blades designed to cut and remove tissue proliferation within a stent and also to reopen stents.

  • Patent number: 6428498
    Abstract: A medical device 10 particularly adapted for debriding an abscess, phlegmon, or hematoma in a human or veterinary patient, for removing debrided and other materials from the abscess and for draining the abscess first includes a flexible catheter 12 having a longitudinally extending flow lumen 14, a rounded distal tip 16, a side portion 18 extending proximally from the distal tip 16 and an oval or other lateral opening 20, 44 or 46 extending through the side portion 18. The device also includes a cutting cannula 22 positionable in and longitudinally slidable in the flow lumen 14 in the catheter 12. The cannula 22 has an open distal end 24 and a sharp, beveled circumferential cutting edge 26 formed on the open distal end 24, the circumferential cutting edge 26 being disposed perpendicularly to the flow lumen 14 of the catheter 12.

  • Patent number: 6368355
    Abstract: A self-expanding stent structure is provided having a main portion that expands to a first diameter and a branch portion that expands to a second diameter, different the first diameter, the main portion having a link portion that forms a flexible linkage to, and forms part of, the branch portion. The self-expanding structure may be compressed to a reduced diameter for delivery, and resumes an expanded diameter during deployment. The self-expanding stent structure also may be advantageously incorporated in an asymmetric stent-graft system. Methods of use are also provided, wherein the main portion of the self-expanding structure, when deployed in a trunk vessel, may be used to anchor the branch portion in a branch vessel.

  • Patent number: 5776186
    Abstract: Graft apparatus, delivery devices and methods for use in stent-graft systems are provided for use in treating aneurysms occurring in hollow-body organs or vessels and for treating arterio-venous fistulas. The graft and graft delivery devices provide the clinician with complete control over the location of the graft at any time prior to implantation of the stents, even when the graft is completely deployed from its introducer catheter. The graft and graft delivery devices also permit retrieval of the graft should it be desired to substitute a graft of a different size or to abort the procedure.

  • Patent number: 5524635
    Abstract: A hand held vibrating device which imparts a combination of transverse and longitudinal vibrations to a guide wire, to assist in advancing the guide wire through a blood vessel and through a stenosis in a blood vessel. The vibrating device contains a motor which drives a set of gears, rotating an eccentric pin. The rotation of the eccentric pin is translated to pivoting of an oscillating arm by the essentially longitudinal movement of a connector bar. The oscillating arm is attached to the guide wire by a releasable collet. Pivoting of the collet by the oscillating arm results in the introduction of a combination of transverse and longitudinal motion to the guide wire.

  • Patent number: 5443078
    Abstract: A method of using a hand held vibrating device for transversely vibrating a guide wire in performing angioplasty and atherectomy procedures. The sinusoidal vibrations introduced into the wire by the vibrating device permit the guide wire to be more easily passed through a blood vessel or a stenotic segment of a blood vessel. The guide wire is threaded through a blood vessel until resistance is met. The guide wire can then be clamped to the vibrating device, which is selectively actuated and manipulated to sinusoidally vibrate the wire, overcoming the resistance, and facilitating the further advancement of the guide wire.

  • Patent number: 5243997
    Abstract: A hand held vibrating device for vibrating a guide wire used in angioplasty and atherectomy procedures. The vibrating device permits the guide wire to be more easily passed through a stenotic segment of a blood vessel. The vibrating device includes a case, an electric motor mounted within the case, and a clamp member coupled to the electric motor for releasably securing and vibrating the guide wire. In use, the guide wire is threaded through a blood vessel to the site of a stenosis. The guide wire can then be clamped to the vibrating device, which is selectively actuated and manipulated to vibrate and push the guide wire through the stenosis.
