  • Patent number: 9974670
    Abstract: A tack device for holding plaque against blood vessel walls in treating atherosclerotic occlusive disease can be formed as a thin, annular band of durable, flexible material. The tack device may also have a plurality of barbs or anchoring points on its outer annular periphery. The annular band can have a length in the axial direction of the blood vessel walls that is about equal to or less than its diameter as installed in the blood vessel. A preferred method is to perform angioplasty with a drug eluting balloon as a first step, and if there is any dissection to the blood vessel caused by the balloon angioplasty, one or more tack devices may be installed to tack down the dissected area of the blood vessel surface, in order to avoid the need to install a stent and thereby maintain a ‘stent-free’ environment.

    Abstract: The present invention is directed to an inflated interspinous spacer. The interspinous spacer is inserted into the interspinous space between adjacent spinous process in a deflated or unexpanded state, and is inflated or expanded with an injectable filler material. Upon inflation, the spacer preferably distracts the spinous processes and assumes a shape that retains the spacer in position and preferably mechanically locks with the spinous processes. The spacer includes two separate balloons configured to have different compressive modulus so that one balloon is softer and more deformable than the other balloon.

  • Patent number: 9078698
    Abstract: An obturator assembly for use in dissection of tissue includes an obturator housing, an obturator member mounted to the obturator housing and an obturator sleeve coaxially mounted about the obturator member and adapted for reciprocal longitudinal movement between a retracted position and an extended position. The obturator member includes an obturator rod and a penetrating end. The penetrating end defines a substantially planar dissecting segment and a central rod segment extending from the planar dissecting element. The planar segment of the penetrating end defines atraumatic outer edges which may be arcuate in character. In one embodiment, the distal entry surface of the central rod segment and the atraumatic edges of the planar dissecting segment are at least partially exposed from the nose shield when in the extended position of the obturator sleeve. The obturator sleeve may include a generally tapered nose shield for at least partially accommodating the penetrating end.

  • Patent number: 9072893
    Abstract: Apparatus for delivering brachytherapy to a target tissue region includes an elongate body including a proximal end, a distal end sized for introduction into a tissue tract and carrying a plurality of elongate members including pathways for receiving a source of radiation. The elongate members are movable between collapsed and expanded configurations. During use, a tract is created through tissue, and the elongate body carrying the elongate members is advanced through the tract into a target location with the elongate members in the collapsed configuration. The elongate members are directed to the expanded configuration at the target location, and radiation is delivered to treat tissue at the target location, e.g., by introducing one or more radiation sources along the pathways.
