摘要:
An arteriovenous shunt assembly including a shunt and a pull wire operated flow control mechanism. The shunt has a tubular body that defines a fluid passageway between a first end and a second end thereof The pull wire mechanism includes a portion disposed around the tubular shunt in at least one loop. The at least one loop may be selectively tightened or loosened remotely from the shunt to regulate the rate of blood flow through the tubular shunt.

In an embodiment, a device for loading a prosthesis onto a delivery system comprises a cap and a reducing member. The cap has a piston member that seats a prosthesis. The piston member has at least one side wall configured to contact a portion of the side of the prosthesis seated therein. The reducing member has a conical wall, a first open end, and a second open end. The first open end is configured to receive the piston member. The reducing member reduces an external dimension of at least a portion of the prosthesis seated in the piston member as the prosthesis is moved along an inner surface of the conical wall.

A process for preparing high VI lubricating oil basestocks comprising hydrotreating, hydrodewaxing and optionally hydrofinishing. The hydrotreated feedstock is hydrodewaxed using a dewaxing catalyst that has been selectively activated by oxygenate treatment. The hydrodewaxed product may then be hydrofinished.

Heart valve delivery systems and methods of delivering and implanting heart valves using delivery catheters are disclosed. The delivery systems can include a handle assembly which can include a first control mechanism, a second control mechanism, and a decoupling mechanism. The delivery systems can also include a delivery catheter extending from the handle assembly. The delivery catheter can include an outer shaft, which can be controlled by the first control mechanism; a prosthesis containing capsule comprising a proximal capsule portion connected to the outer shaft, and a distal capsule portion releasably coupled to the proximal capsule portion. After deploying a valve prosthesis, the capsule can be closed by activating the decoupling mechanism in the handle to rapidly close the distal and proximal capsule portions together. The delivery system can also include a centering element to guide the distal and proximal capsule portions together.

A releasable connector assembly comprising a socket body 2 and a plug body 3. The socket body 2 has a set of channels 15 formed therein and the plug body 3 having a corresponding set of radial tabs 7 formed thereon, the channels 15 forming a keyway for the tabs 7 such that load bearing projections 5, 14 on the bodies are releasably engageable in the manner of a bayonet coupling. The assembly is characterised in that a set of locking pins are provided on the socket member that are extendable into the channels 15 so as, in use, to trap the tabs 7 in undercuts 15k of the channels 15, thereby preventing unintentional release of the plug 3 from the socket 2, and retractable from the channels 15 so as to enable release of the plug 3 from the socket 2.

A person is viewing a display. By evaluating tracked information about the person, the display and/or the content being viewed, a tracking system determines that an opportunity exists to present an advertisement that is relevant to the person in the context of the person currently viewing the display. The tracking system provides advertiser data for the advertisement and instructions for generating the advertisement to a synthesis system local to the viewer and the viewer's display system, which dynamically synthesizes the advertisement and provides it to the display.

A method of categorizing fasteners and construction connectors by size and type using a color coding system. Each fastener receives a designated and distinct color contained on the surface that is exposed before and after installation. The colors are preselected to define one or more physical properties of the fasteners. A color key is provided to determine the physical properties of the fasteners based on the coloring of exposed portions of the inserted fasteners. Similarly, construction connectors receive a designated and distinct color contained on the surface that is exposed before and after installation. The color represented on the surface of the construction connector is such that the corresponding fastener is the same color.

A sparker array includes a plurality of sparker sources of sound and light emissions, the plurality of sparker sources arranged in a geometric pattern with respect to a region, the array configured to deliver a maximal acoustic output to the region. Sparker sources may include reflectors. A single electrical source to drive a sparker array may be employed. A sparker system may include two or more sparker arrays. A time delay may be employed to trigger electrical circuits of the sparker arrays. Sparker arrays may be used to deliver shock waves with increased operational life, consistency and efficacy for specific applications.

A pipe connector comprises a tubular pin member 1 having a generally frustoconical outer peripheral surface 3 and a tubular box member 2 having a generally frustoconical inner peripheral surface 4 corresponding to the frustoconical outer peripheral surface 3 of the pin member 1 and which overlies the frustoconical surface 4 of the pin member 1 when the members 1, 2 are fully engaged together. A circumferentially extending groove 14, 15 is formed in each of the pin member 1 and the box member 2 at the root end of the frustoconical surface 3, 4 thereof, and a nib 12, 13 is formed on the tip of each of the pin 1 and box 2 members such that, upon full engagement of the pin 1 and box 2 members, the nibs 12, 13 of the pin 1 and box 2 members engaging respectively in the grooves 14, 15 of the box 2 and pin 1 members so as to radially restrain the free ends of the pin 1 and box 2 members. Each nib 14, 15 is an interference fit with its mating groove so as to form a seal therewith, wherein at least one of the inner diametrical surface 14a of the groove 14 in the box member 2 and the outer diametrical surface 15a of the groove 15 in the pin member 1 is inclined relative to the abutting surface 12a; 13a of the nib member 12, 13 engageable therein, such that said abutting groove and nib surfaces 12a, 14a; 13a, 15a diverge from each other towards the bottom of the groove 14; 15.
