Abstract: This invention is a novel method for perfusion of a porous implant which achieves efficient interpenetration of desired factors into and removal of undesirable factors from the pores of the implant, cleaning of the implant, efficient passivation of the implant (inactivation of pathogens, microorganisms, cells, viruses and the like and reduction in antigenicity thereof), and the novel implant produced by such treatment. The process presents a system wherein the rate of pressure cycling, the fact of pressure cycling, and the amplitude of pressure cycling, results in highly cleaned tissues and other implants for implantation.

Abstract: This invention relates to implants useful as stents for opening or strengthening biological conduits, or as grafts or conduits for replacing or connecting portions of biological tissues having a lumen. Accordingly, the implants of this invention may be applied in portions of the peripheral and coronary vascular system, biliary, urinary, esophageal, digestive, ocular, tracheal, bronchial, reproductive, and neural systems. The implant comprises a segment of bone having a lumen through at least a part thereof, and wherein at least a portion of the implant is demineralized so as to be pliable.

Abstract: A system and method for generating bio-active frequencies. Such generated frequencies are very precise and are accurate within 0.001 Hz. The frequencies are used to advantage in health science applications such as killing microorganisms and viruses and enhancing tissue regeneration and may be used in various commercial and industrial applications, such as food processing. A specific precise frequency synthesizer is controlled by a programmable control that instructs the synthesizer to generate a specific precise frequency or a series of precise frequencies. A keyboard is actuable by a user to select a specific frequency or sequence of frequencies or a preprogrammed series of frequencies. Depending upon the specific frequency being generated, a circuit gates the generated signal ON or OFF with a predetermined determinable periods being selected for such ON/OFF periods.
