Abstract: Battery powered and wall plug powered handheld therapy devices for treating a variety of ailments such as inflammations, nerve problems, joint pain, muscle pain, as well as gall bladder type problems. The device can have a multi-faced shaped emitting main crystal with side crystals that can be used with a flashing strobe light source to generate variable frequency pulses toward the effected body part to be treated. Alternatively, or additionally, the device can use an electromagnetic type generator to generate fixed frequency signals toward an effected body area to be treated. Up to approximately six small crystals or more can be positioned to a base portion of the emitting crystal on each of the six faces of the emitting crystal. The side crystals can be used as antennas to receive ambient energy in order to be focused by the main crystal. Hand grips or a floor based stand can be used to elevate the device up to approximately 18 inches above the patient.

Abstract: A ventricular assist device for temporary assistance to persons with failing or damaged hearts. A container includes inlet and outlet ports to the patient's circulatory system and a pumping component. It can also include a power source, and control elements, as well as other ventricular assist components. The pumping component operates off of a power supply, consumes a low amount of power, produces good pumping efficiency, and circulates the blood in an advantageous flow pattern with minimal trauma to the blood. The pumping device utilizes a moveable tubular member in which is positioned a one-way valve. The tubular moveable member is put in fluid communication with the flow path from inlet to outlet ports of the pumping component. The tubular member is reciprocatable by, for example, a solenoid and a return spring.

Abstract: A system for pumping of fluids, particularly biological fluids such as blood, including a tubular length of magnetostrictive material. One-way valves are positioned generally in opposite ends of the tubular material. Fluid flow conduits are connected to the opposite ends of the tubular material. A magnetic field is imposed, generally by an electric coil, in a pulsed fashion to the tubular material to cause alternatingly magnetostriction and relaxation of the tubular material. This causes a reciprocating variation in the distance between the one-way valves which oppositely are opened and closed to produce a pumping action through the tubular material.

Abstract: A disposable tubular pneumotachometer in which the air-resistive material covering over the air outlet is a fabric with multiple sub-miniature tubular apertures to provide capillary air flow and, in the preferred form, has a uniformly diverging air outlet formed by air outlet openings through the wall of the pneumotachometer tube and an imperforate proportionally tapered air-diverging surface facing the air outlet openings.

Abstract: A method of exposing a patient's extremity to light of two wavelengths and detecting the absorbance of the extremity at each of the wavelengths is provided comprising the steps of: (a) generating pulses of light having the first wavelength at a first pulse frequency; (b) generating pulses of light having the second wavelength at a second pulse frequency; (c) exposing the extremity to the first and second pulses; (d) producing an electrical signal corresponding to the total amount of light transmitted through the extremity; (e) separating the electrical signal produced in step (d) into a first amplitude-modulated electrical signal at the first pulse frequency and a second amplitude-modulated electrical signal at the second pulse frequency; and (f) demodulating the first and second amplitude-modulated electrical signals to produce a first signal corresponding to the amount of light transmitted through the extremity at the first wavelength and a second signal corresponding to the amount of light transmitted thro
