摘要:
An arteriovenous shunt assembly including a shunt having a hollow bore between open first and second ends thereof and a valve slidably disposed through the hollow bore. The valve includes means for retaining the valve in a closed position or in any of various selected open positions that provide corresponding different rates of blood flow through the shunt assembly. In some embodiments, the AV shunt assembly is self-expandable from a collapsed tow-profile configuration employed during transluminal delivery. The valve position in the hollow bore may be adjusted in vivo by inflating a catheter balloon in a blood vessel to bear against an end of the valve. Methods for using the shunt assembly are also disclosed.

A system and method for generating a set of programming instructions for manipulating a vehicle frame are provided. A frame computing device obtains configuration information for an identified vehicle frame. The frame computing device sub-divides the selected vehicle frame into a set of regions and obtains programming modules for each of the components mounted in the set of regions. The frame computing device processes the program modules to generate a cumulative set of programming instructions for manipulating the vehicle frame.

Techniques are disclosed for supplying users in an online environment with a safe and effective chat facility. The chat facility is “safe” in the sense that the ability of users to compose inappropriate messages is greatly restricted, while “effective” in the sense that users are still allowed a broad range of expressivity in composing and exchanging chat messages.

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.
摘要:
A method for making a coated food product having a heat susceptible coating is disclosed. In one aspect, the invention is directed towards a nut having a proteinaceous or fruit-based coating with no visible scorching in the outer, visible coating layer. In one aspect, the food center is par-coated with or without a heat susceptible coating, pre-roasted, finished coated with or without a heat susceptible coating, and cooked. In another aspect, the food center is first coated with a heat susceptible coating, then coated with a non-heat susceptible coating and cooked. In yet another aspect, the food center is coated with a heat susceptible coating and then cooked in a two-stage process whereby the first stage is at a hotter temperature than the second stage.

摘要:
A system includes an elongate catheter having a self-expanding frame disposed at the distal end of the catheter. The frame includes a plurality of longitudinal struts defined by parallel slots. The frame may be constrained into a radially compressed configuration for delivery to a treatment site. A helical balloon is mounted about the frame. Upon release from the constraining mechanism, the frame returns to a heat-set radially expanded configuration to initiate dilation of a treatment site in a patient. Inflating the balloon around the expanded frame further expands the initial radial dilation of the site. Proximal and distal ends of the slots are unobstructed by the balloon to permit flow of a fluid through the slots and through a lumen defined by an interior surface of the balloon when the frame is in the radially expanded configuration.
摘要:
A fogger propellant system configured to discharge an antimicrobial mixture in order to substantially inhibit growth and reproduction of microbes in the area adjacent to the system. The system further includes a container that has disposed therein a propellant and an antimicrobial compound. The antimicrobial compound is dispersed from the container in a gaseous form and further includes a fragrance oil to achieve a desirable odor during the dispersal of the antimicrobial compound. The container includes a nozzle having an aperture journaled therethrough in order to facilitate the dispersal of the antimicrobial compound. A trigger is operably connected to the nozzle to commence the release of the antimicrobial compound.
