  • Publication number: 20070106365
    Abstract: A stent deployment system includes a catheter shaft, an expandable member mounted to the catheter shaft, and one or more stents or stent segments slidably positioned on the expandable member. The stent deployment system is adapted for deployment of stents or stent segments in very long lesions and in tapered and curved vessels. The stent deployment system facilitates slidable movement of a stent in a distal direction relative to the expandable member while inhibiting slidable movement in a proximal direction relative to the expandable member.

  • Publication number: 20070088368
    Abstract: Delivery catheters and systems are adapted for delivering multiple discreet prostheses in body lumens. An exemplary delivery catheter comprises a sheath, a pusher for moving the prostheses relative to the sheath, and a valve member for selectively retaining the prostheses in the sheath. For balloon expandable stents, an elongated shaft and an expandable member are slidably disposed in the sheath, and the prostheses are positionable on the expandable member for deployment in the body lumen. The valve member allows a selected number of prostheses to be deployed from the sheath while retaining other prostheses within the sheath.

  • Publication number: 20070038927
    Abstract: Systems and/or methods (“tools”) are described that convert or present conversion problems for electronic documents. The tools may convert a generally unstructured electronic document to a generally structured electronic document using non-visual textual and layout information of the unstructured document. The tools can also present possible problems with this or other types of conversion. And the tools can enable a user to alter an electronic document's schema without altering its visual layout.

  • Publication number: 20070027521
    Abstract: Apparatus for delivering stents to body lumens include one or more tubular prostheses carried at the distal end of a catheter shaft, a sheath slidably disposed over the prostheses, and a guidewire tube extending from within the sheath to the exterior of the sheath through an exit port in a sidewall thereof. A guidewire extends slidably through the guidewire tube. The sheath can be moved relative to the catheter shaft and the guidewire tube to expose the prostheses for deployment. Methods of delivering stents are also provided.

  • Publication number: 20060235334
    Abstract: Catheters, kits, and methods are provided for removing material from a body lumen. The catheters and methods may be used in a variety of body lumens, including but not limited to coronary and other arteries. In general, the catheter has a cutting element that cuts material while the material is engaged by a material capture device on the catheter body. Preferably, the material capture device tensions the material during cutting, which reduces the amount of cutting force required. The material capture device typically follows a path that draws material into the catheter body. Preferably, but not necessarily, the material capture device may be arranged on the catheter body to advance along a path outwardly from the catheter body into the material and then inwardly towards the catheter body to tension the material. The cutting element on the catheter body moves between a first position and a second position to cut the material while in tension.

  • Publication number: 20060201713
    Abstract: Method for drilling horizontal or deviated water wells through hard and fragmented rock formations that are prone to caving, such as Hawaiian basalts. The method may be used to drill into basal aquifers directly underlain by salt water, compartmented aquifers, and perched aquifers. The method uses deviated drilling and may use formation pre-grouting, casing drilling, and/or percussion drilling, and a percussion drilling tool may be combined with a casing drill string.

  • Publication number: 20060195126
    Abstract: An atherectomy catheter is provided for excising and imaging material in a body lumen. In one embodiment, the catheter comprises a catheter body, a cutting blade, and an imaging device. The cutting blade is mounted on the catheter body and configured to move between a first position and a second position relative to an aperture or cutting window. When the cutting blade is in the second position, the blade substantially closes the aperture on the catheter body. The imaging device which is mounted on or otherwise coupled to the cutting blade is configured to be in an imaging position when the cutting blade substantially closes the aperture or cutter window. This allows the imaging device to survey material within the cutting zone of the atherectomy catheter. By allowing the imaging device to view materials within this cutting zone, material may be imaged and then removed from the body lumen without having to reposition the catheter between each step.

  • Publication number: 20060101943
    Abstract: This invention uses nanoparticle mixtures to broaden the range of economic materials, improve performance across this broader range, and thereby lower costs of hydride and other storage systems. Nanoparticles can have dramatically different mechanical, chemical, electrical, thermodynamic, and/or other properties than their parent (precursor) materials. Because of this fundamental characteristic, nanophase materials can greatly improve the range of possibilities of materials selection, performance, cost, and practicality for hydride storage systems, advancing the early commerciality of such systems for hydrogen fuel cells or other applications. Among such hydrogen storage improvements are cheaper and better-performing metals, alloys, and/or compounds; lower weight; and reduced storage volumes.

  • Publication number: 20060020800
    Abstract: A method is disclosed for mixed enclave operation of a computer network with users employing a multi-level network security interface and users without any network security interface. Either the network security user selects or the network security interface automatically selects whether communications are permissible with other unsecured users. Where a mixed enclave operation is selected, the network security user identifies when communications are being undertaken with another secured user or a non-secured user. Communications with a non-secured user at a lower security level entail securing the data residing with the secured user from transmission back to the non-secured user.

  • Publication number: 20060010611
    Abstract: The invention limits water level in a rinse cycle to a fraction of the water in the wash cycle. A microprocessor based electronic circuitry device that may be wired inside the front panel of the normal (factory) “top loading” automatic clothes washer or a “front loading” automatic clothes washer. Interfaces exist to the water valves and timer motor from the micro-controller. The retrofitted on original equipment micro-controller commands the hot and cold valves to start filling the tub and measures the analog water level input from the water level sensor. This number is stored in the micro-controller memory as a “wash water level” during a first cycle (wash cycle). If the Water Saver Disable switch is enabled by an operator the “Wash Water Level” is divided by two providing a “Rinse Water Level” (second cycle) that is one half the wash or first cycle, or another fraction of that amount.

  • Publication number: 20050288764
    Abstract: Prosthesis delivery devices and methods are provided that enable precise control of prosthesis position during deployment. The prosthesis delivery devices may carry multiple prostheses and include deployment mechanisms for delivery of a selectable number of prostheses. Control mechanisms are provided in the prosthesis delivery devices that control either or both of the axial and rotational positions of the prostheses during deployment. This enables the deployment of multiple prostheses at a target site with precision and predictability, eliminating excessive spacing or overlap between prostheses. In particular embodiments, the prostheses of the invention are deployed in stenotic lesions in coronary or peripheral arteries, or in other vascular locations.
