Abstract: Described herein are systems, devices, and methods for removing material from patient vasculature. In some embodiments, an aspiration device may include a sheath and a catheter slidably disposed within the sheath and defining a lumen. The catheter may include a distal end portion and an elongate portion, the distal end portion being disposable adjacent to a clot, the elongate portion being couplable to a vacuum source that is configured to apply a negative pressure to the lumen to draw the clot into the distal end portion. The distal end portion may include a plurality of sections, each of the plurality of sections having a different cut pattern.

Abstract: An orthopedic brace is provided that includes one or more pad plates formed of a light-curable material and a hinge comprising one or more hinge framework elements connected to the one or more pad plates. The pad plates may include an elastomeric shell to contain the light-curable material. A rigid attachment member may be coupled to the elastomeric shell to couple to the hinge framework element.

Abstract: A hip brace is provided which includes an iliac crest pressure plate, a femur pressure plate, a quadriceps pressure plate, and a bracket to connect the plates. The bracket includes one or more adjustable hinges to adjust positioning of at least one of the iliac crest pressure plate, the femur pressure plate, or the quadriceps pressure plate to correspond with dimensions of a user. The bracket further includes a range of motion restriction dial to control flexion or extension of the hip of the user, where the range of motion restriction is positioned on the bracket to correspond to the femur pressure plate.

Abstract: A process for shaping threaded metal and ceramic parts from powders and molding compositions therefor is disclosed. Parts produced by this process are formed net shape without the need for machining or other finishing operations. The process comprises forming a mixture containing metal powders, ceramic powders or mixtures thereof, a gel-forming material and an aqueous gel-forming material solvent, and molding the mixture in a mold containing internal and/or external threads under conditions of temperature and pressure to produce a self-supporting threaded article.

Abstract: A process for molding metal knife blades from powders and molding compositions therefor are disclosed. Parts produced by this process are formed near net shape without the need for machining or other finishing operations. The process comprises forming a mixture containing metal powders, a gel-forming material and an aqueous gel-forming material solvent, and molding the mixture in an injection molding machine under conditions of temperature and pressure to produce a self-supporting knife blade having a sharp edge.

Abstract: Molding compositions for shaping parts from stainless steel powders are disclosed. The process comprises the steps of forming a mixture comprising stainless steel powder, a gel-forming material having a gel strength, measured at a temperature between 0° C. and about 30° C. and a gel comprising about 1.5 wt % of the gel-forming material and water, of at least about 200 g/cm2, and water, and molding the mixture at a temperature sufficient to produce a self-supporting article comprising the powder and gel. The preferred gel-forming material is an agaroid and the preferred molding process is injection molding.

Abstract: A novel process for preparing injection molding feedstock compounds in a continuous manner amenable to high volume manufacturing includes the steps of forming a mixture including metal and/or ceramic powders, a binder and a liquid carrier, supplying the components in a continuous manner to a twin screw extruder, forcing the homogeneous compounded mixture through an exit die, and cutting the extruded strand into pellets. The pellets are useful for shape-forming articles by various molding processes.

Abstract: Molding compositions for shaping parts from stainless steel powders are disclosed. The process comprises the steps of forming a mixture comprising stainless steel powder, a gel-forming material having a gel strength, measured at a temperature between 0.degree. C. and about 30.degree. C. and a gel comprising about 1.5 wt % of the gel-forming material and water, of at least about 200 g/cm2, and water, and molding the mixture at a temperature sufficient to produce a self-supporting article comprising the powder and gel. The preferred gel-forming material is an agaroid and the preferred molding process is injection molding.
