Abstract: An inventive method for performing gastric bypass surgery and a gastric bypass band that is used in conjunction with the surgical method is disclosed. The inventive method involves separating a top portion of the stomach along with the esophagus from the remainder of the stomach, and re-connecting the separated portion to the small intestine to form a gastric pouch of about 20-30 cc in size. The inventive gastric band is placed midway along the gastric pouch to act as a restrictor valve to limit the amount of food passing through the valve. The band also retains food within the gastric pouch to give the patient a feeling of satiety. The band is comprised of an expansion-resistant section combined with a one-way latch mechanism. The latch has a curved orientation so that the band is formed into a radial profile when placed around the gastric pouch.

Abstract: An electrolysis cell is provided, which includes an anode electrode and a cathode electrode. At least one of the anode electrode or the cathode electrode includes a first plurality of apertures having a first size and/or shape and a second plurality of apertures having a second, different size and/or shape.

Abstract: The invention is directed to an aggregate floor coating and method/system for applying the same. In one embodiment, a base layer of epoxy or equivalent material may be applied to a prepared floor surface. Prior to curing of the base layer, a quantity of aggregate flooring material, e.g., quartz particles, may be broadcast over the exposed surface of the base layer. Upon curing of the base layer, an ultraviolet (UV)-curable topcoat layer may be applied. Exposure of the UV-curable topcoat layer to one or more specific wavelengths of UV energy results in fast curing of the topcoat layer, permitting quick resumption of floor traffic. Coatings of the present invention provide numerous advantages, such as allowing application of aggregate floor coatings in well-lit, e.g., sun-exposed areas.

Abstract: A method and apparatus for destroying blood borne pathogens is disclosed which utilizes a low intensity direct current to generate positive particles from various metals which destroy viral pathogens. A first electrode comprised of a metal such as silver is inserted into a patient's venous system. Then, a second electrode is placed on the patient's exterior in the vicinity of the first electrode. A low intensity direct current is applied to the first metal electrode which releases silver cations to be bonded to the virus, resulting in the denaturing of the virus. The first electrode is placed in the venous system of the infected patient via a catheter.
