  • Patent number: 6979333
    Abstract: Disclosed are methods of spinal fixation involving application of a liquid medium which cures, hardens, polymerizes or otherwise serves to bind adjacent vertebrae together. The fixation which results from this binding may be temporary or essentially permanent in duration, and may be used to treat conditions or disease of the spine, such as inflammation, instability or fracture. In a preferred embodiment, the liquid medium comprises a low viscosity cyanoacrylate-based adhesive.

  • Patent number: 6287323
    Abstract: Disclosed is a device for delivering tissue adhesives and/or sealant patches to a surface which covers or surrounds a perforation in a lumen, cavity or organ, or potential lumen or cavity, within a human or other animal. Also disclosed is a method of delivering tissue adhesives and/or sealant patches to a surface which covers or surrounds a lumen, cavity or organ, or potential lumen or cavity. The method is particularly suited to sealing perforations in vascular walls, such as after arterial access for Percutaneous Transluminal Coronary Angioplasty (PTCA), Percutaneous Coronary Angiography and Percutaneous Coronary Atherectomy and other diagnostic and therapeutic procedures.

  • Patent number: 6155265
    Abstract: Methods and compositions for closing and sealing a wound, laceration, incision, or other percutaneous opening using an adhesive. In one preferred embodiment, the sides of the percutaneous opening are brought together in apposition and the adhesive is applied to the opening and the skin immediately adjacent thereto. Adhesives used in the methods exhibit sufficient viscosity to substantially prevent flow of the adhesive into the percutaneous opening. In a preferred embodiment, the adhesive is a sealing medium comprising an adhesive component and a microparticulate component. Preferred sealing media comprise cyanoacrylates combined with fumed silica. In such embodiments, the fumed silica is present in an amount sufficient to substantially prevent the medium from flowing into the opening at normal skin temperature.

  • Patent number: 5941895
    Abstract: Disclosed is a removable cardiovascular stent, an apparatus for the retrieval of the stent and a method for removal of the stent. The removable stent includes radially inwardly extending engagement members for contacting an extraction catheter. The extraction catheter includes a tubular body and an axially moveable guidewire, each adapted to grasp the engagement members of the tubular stent. The stent is elongated in an axial direction thereby reducing the cross-sectional area of the stent. The stent can be removed directly, or can fit within the tubular body of the extraction catheter for atraumatic removal from the treatment location.

  • Patent number: 5632762
    Abstract: Disclosed is a specially tapered balloon such as for sizing an implantable tubular stent that has been positioned within an ostium. In one application of the present invention, a stent is positioned within the right coronary ostium, and the tapered balloon of the present invention is positioned within the stent to provide a radial outward flare on the proximal end of the stent. In this manner, the proximal end of the stent is pressed back against the aortic wall surrounding the right coronary ostium, thereby minimizing any obstruction to blood flow in the aorta, and possibly reducing the risk of restenosis at the right coronary ostium.
