Title: Multilayer, laminated card with embedded security element having relief structures
Inventor: KELLER MARIO
IPC: B42D25/00
Filed: 2001-02-20
Abstract: A card, in particular credit card, identity card, bank card or the like is proposed that includes a plurality of laminated layers between which a security element with a relief structure, in particular holographic diffraction structures, is embedded. The ma-terials are selected so that the softening temperature of the security element layer hav-ing the relief structure has a higher softening temperature than the card layers between which the security element is laminated. This permits the multilayer laminated card to be produced by conventional laminating methods without appreciably impairing the relief structure by the pressures and temperatures thereby occurring. Special combina-tions of materials and in particular suitable materials for the layer having the relief structure are proposed.

Title: Expansible shearing catheters for thrombus and occlusive material removal
Inventor: EVANS MICHAEL A
IPC: A61M25/10
Filed: 2001-03-30
Abstract: Devices, methods, kits, and methods remove obstructive material from the vasculature and other body lumens. Expansible baskets may be used as cooperating radially expansible shearing members. Helically oriented struts of each basket may wind in a uniform circumferential direction. The struts can be independently flexible, allowing the shearing members to flex axially together. The inner basket may be rotatably driven and may use an axial pump extending proximally from the shearing members and/or a distal penetrator for advancing into an occlusion which inhibits guidewire access. The struts may slide substantially continuously across each other, and may be sufficiently aggressive for highly effective thrombectomy. A rotationally static and axially flexible outer basket may provide a safe, limited atherectomy treatment.

Abstract: A method of mounting a member such as a rail to a support surface such as a floor, made of a precast concrete material, without penetrating the floor. The rail mounting system for implementation of the novel method includes a base plate secured to the upper surface of the floor via an adhesive, with one or more connectors extending upwardly from the base plate. An anchor plate is secured to the rail, and adjustment screws are interconnected with the rail for adjusting the elevation of the rail relative to the base plate. When the desired elevation of the rail is attained, engagement members such as nuts are secured to the threaded connectors extending upwardly from the base plate, to fix the height of the anchor plate, and thereby the rail. A grout layer is then applied between the plate and the anchor plate. After the grout layer is set, the leveling screws are removed and a topping layer of concrete is applied over the components of the mounting system so as to encapsulate the base plate, the anchor plate and the engagement members.
