  • Publication number: 20090082843
    Abstract: The invention is directed to a self-expanding stent for implantation into a body lumen, such as an artery. The stent consists of a plurality of radially expandable cylindrical elements generally aligned on a common longitudinal stent axis and interconnected by a plurality of interconnecting members placed on the stent in a collinear arrangement such as to create at least one continuous spine which extends along the length of the stent. The invention is also directed to a stent delivery system for implantation of a stent in a vessel which includes an outer tubular member having a restraining sheath and an inner tubular member having a distal end which has a compressed stent mounted thereto. The proximal end of the inner tubular member is connected to a housing assembly which prevents the inner tubular member from moving when the outer tubular member is retracted to deploy the stent.

  • Publication number: 20070256255
    Abstract: A process for making a colored article of manufacture is disclosed. Accordingly an article of manufacture is first prepared of a material selected from the group consisting of metal, wood, glass, ceramic, masonry and polymeric materials. A polymeric coating (superstrate) is then applied to at least a portion of the surface of the article. At least a portion of the superstrate is brought into contact with a material system that contains (i) water, (ii) a carrier, (iii) a dye and (iv) a diol, under conditions calculated to bring about diffusion of said dye into said superstrate.

  • Publication number: 20040044399
    Abstract: A longitudinally flexible stent having high visibility under fluoroscopy for implanting in a body lumen. The stent includes a plurality of radiopaque interconnecting elements, configured to be expandable and encapsulated by polymeric material in a coil-like configuration, that are connected to a plurality of cylindrical elements at least at distal and proximal ends of the stent such that the radiopaque interconnecting elements are visible under fluoroscopy to enable identification of the position, diameter, and length of the stent at the implantation site. Alternatively, the stent includes a plurality of radiopaque interconnecting elements having a polymeric material filled with a radiopaque material attached to the cylindrical elements of the stent at least at the distal and proximal ends of the stent.

  • Patent number: 6638290
    Abstract: A connector assembly for connecting a surgical saw blade to a housing of a surgical instrument. The connector assembly allows a surgeon to align, insert and lock the surgical blade in the collect of the surgical instrument without any special tools, and further provides a stable and robust platform for mounting the surgical saw blade thereto. The connector assembly includes a gripper having a centrally located bore and a pair of opposing shelves. A shaft having shoulders is slidably fitted within the bore of the gripper. The shoulders communicate with ledges of the shelves to prohibit movement of the finger gripper. This same mechanism also prevents movement of a surgical saw blade, once inserted within the slot of the shaft, from becoming dislodged or ejected from the connector assembly. A biasing spring biases the gripper in a first position, but the gripper can move between the first position and a second position.
