Abstract: A device is designed in the form of glasses with a frame (10) having a frontal portion (20), temporal portions (30) abutting the frontal portion on two sides, and temples (40) attached to the temporal portions. Each temporal portion (30) comprises an intake fan (31) with an air filter (50) and a discharge air duct (60), wherein nozzles (63) of the two air ducts (60) are oriented towards one another, providing the formation of substantially counter-directed streams of clean air directly under the nostrils of a user, with the result that a region of high pressure is formed, keeping non-purified ambient air from entering the nostrils.

Abstract: Medical devices, as well as related systems and methods, are disclosed.

Abstract: A fluid infusion system comprises a flexible elongated body having a distal end, a proximal end and a fluid transport lumen extending therethrough and a fluid source having a connector for coupling to the proximal end to provide fluid to the fluid transport lumen in combination with an ultrasound energy source delivering ultrasound energy to the fluid to reduce a viscosity of the fluid and a waveguide directing the ultrasound energy to a desired region of the fluid.

Abstract: Described is a catheter which includes a reinforced polymer shaft. The polymer includes nano particles having a dimension of less than about 6 nm. Described is also a method of forming a medical device. Granules of a selected polymer are prepared. Reinforced granules of the selected polymer are prepared. The reinforced granules include nano particles. The granules and the reinforced granules are then mixed in a ratio selected to obtain a desired concentration of the nano particles. The granules and the reinforced granules are extruded to form a substantially tubular element.

Abstract: The present invention provides an air shield comprising side panel assemblies in hinged connection to each rear edge of a sidewall of a tractor and an actuation assembly including a boss in rotational engagement to the frame of the tractor and between a cab and a fifth wheel of the tractor, a lever having an adjustable length engaged to the boss at a first end and engaged to side panel assembly at a second end, and a spring including a first end connected to the side panel assembly and a second end connected to the frame of the tractor between the boss and the rear of the trailer frame.

Abstract: Medical devices, such as catheters, ports, and stents, are disclosed.
