Magnetic decontamination device and method

A device and method for removing metalliferous particles from a powder so that the powder can be reused. A contaminated powder fluid stream flows down tube (6 / 7) into zones A, B and C adjacent the surface of a magnet (4). The flow flows past the surface of the magnet (4) and is directed towards the surface of the magnet (4) by baffles (10A, 10B). The magnet (4) separates metallic particles from powder particles and these metallic particles are removed from the face of the magnet (4) by scraper bars (21) conveyed by endless belts (22) supported by roller sets (23). The device can also include a fan (5) for promoting the movement of air in a counter direction to the delivered powder mixture.

An enhanced cross stream mechanical thrombectomy catheter with backloading manifold having a distal end with outflow and inflow orifices at one side for producing concentrated cross stream jet flow for selective and concentrated thrombus ablation during thrombectomy procedures. The invention provides for suitable distancing of high powered ablation or suction forces from the near walls of the vasculature. Cross stream flow emanating from the one side of the distal end of the catheter resultantly urges the distal end of the catheter and thus the opposing non-orificed side of the distal end of the catheter toward and against the vascular wall to inhibit contact of the inflow orifice with the vascular wall. Features of the invention include a geometrically configured insert to facilitate the backloading or exchange of guidewires.

Continuous liquid stream digital blending system

The present invention consists of a method and apparatus providing for the continuous stream blending, preferably on a mass ratio basis, of two or more liquids. Each individual liquid stream is synchronously dosed in precise mass ratio to a common mixing point. The flow of each stream is on-off or digital. Repeated mass ratio doses of defined and matching flow interval, referred to as synchronous digital flow, interspersed with a defined interval of no flow, constitutes digital flow at a net rate sufficient to meet or exceed some required take-away of the blended liquids. In one preferred embodiment, each dose stream flow is produced and measured by a four element apparatus preferably consisting of a servo motor and controller, a precision positive displacement pump, a Coriolis mass meter and a precision flow stream shut-off device. The servo motor and controller establish and control a periodic and intermittent flow rate necessary to displace a defined mass dose in a precisely defined flow interval. The flow interval is measured against a precision millisecond digital clock. The Coriolis mass meter is used only to totalize mass flow to define the desired mass dose during the defined digital flow interval. The flow stream shut-off device ensures precise delivery of the mass dose to the common mixing point. The flow rate of a stream is automatically adjusted by the control electronics until the required mass dose is delivered in the defined flow interval.
