SANUWAVE Health announced that the U.S. Patent and Trademark Office issued the Company patent relates to a new construction of the spark gap electrodes used to generate acoustic pressure shock waves in SANUWAVE's devices, which allows a longer useful life for the applicators. The twenty claims of the patent cover the construction of the acoustic pressure shock wave applicators that incorporate such electrodes and methods to adjust the spark gap distance in between the electrodes using calculation of equivalent capacitance of the applicator's head.
These new electrodes are ring-shaped with different radial dimensions and are designed with radial fluid holes that facilitate fluid circulation for improved heat dissipation from the electrodes during their service. Furthermore, heat dissipation is also improved by the larger electrode tip surface area, which is a ring-shaped area compared with the conical point-shaped area for the classic design of the electrodes. These advantages makes these electrodes to last longer and thus improving the efficiency of high voltage discharge and a longer life for the applicators that incorporate this type of electrodes.
