  • Publication number: 20090306690
    Abstract: An rotational atherectomy apparatus for abrading tissue, comprising: a flexible, elongated, rotatable drive shaft having a proximal end and a distal end opposite the proximal end; a nose cone operatively attached proximate the distal end of the drive shaft comprising a distal tapered section and a plurality of elongate, flexible members adjacent to the distal tapered section of the drive shaft, each member in the plurality being fixed at both a proximal end and a distal end opposite the proximal end; a proximal mount rotatable with the drive shaft and fixedly connected to the proximal ends of all the flexible members in the plurality; and a distal mount axially separated from the proximal mount and fixedly connected to the distal ends of all the flexible members in the plurality.

  • Publication number: 20090306691
    Abstract: The invention provides a rotational and/or axially translatable atherectomy system, device and method comprising a flexible, elongated drive shaft or catheter comprising an expandable and collapsible conical coil with a cutting edge on the coil's large diameter proximal end. When retracted, the coil's sections are collapsed around each other, held together in the retracted position by a sheath that, when distally retracted, allows the coil to automatically expand. The coil is expanded at a point distal to the occlusion, then pulled proximally to cut the occluding material near the lumen wall. The proximal pulling force may be combined with low-speed rotation and/or translation and/or axial vibration at low to ultrasonic frequency.

  • Publication number: 20060275952
    Abstract: Disclosed are methods for forming an electronic device that comprises a material that functions as an underfill material as well as a thermal interface material simultaneously. The electronic assembly comprising a heat dissipating element, a semiconductor chip, a substrate and a thermally conductive material is also given here, wherein the thermally conductive material serves as an underfill material as well as a thermal interface material simultaneously.

  • Publication number: 20060275608
    Abstract: A B-stageable film that includes a thermal interface material is provided. The film may secure a heat-generating device to a heat-dissipating component, may further cross-link, and may conduct thermal energy from the heat-generating device to the heat-dissipating component. A method of making and using the film is provided, as well as a device that incorporates the film.

  • Patent number: 5827491
    Abstract: The synthetic porous crystalline material, MCM-56, is synthesized by a process comprising the steps of:a) preparing a reaction mixture containing sources of alkali or alkaline earth metal (M) cation, an oxide of an trivalent element X, an oxide of a tetravalent element Y containing at least 30 wt. % of solid YO.sub.2, a directing agent (R), and water, said reaction mixture having a composition, in terms of mole ratios of oxides, within the following ranges:YO.sub.2 /X.sub.2 O.sub.3 5 to 35H.sub.2 O/YO.sub.2 10 to 70OH.sup.-- /YO.sub.2 0.05 to 0.5M/YO.sub.2 0.05 to 3.0R/YO.sub.2 0.1 to 1.0b) crystallizing said mixture at a temperature of about 80.degree. C. to about 225.degree. C., preferably about 125.degree. C. to about 140.degree. C., to form crystals of MCM-56,c) terminating said crystallization prior to the formation of a significant quantity of MCM-49, andd) separating the MCM-56 crystals from the reaction mixture.
