  • Patent number: 5549640
    Abstract: A system for application of electromechanical energy to generate full cycle linear oscillations imposing soft tissue strains which activate natural biochemical mechanisms whereby wound healing is enhanced through reduced scar tissue formation, swelling, pain, healing time, and increased wound strength is thereby provided. In essence, the device and method of this invention provides such enhanced wound healing by utilization of an applicator head which is mounted on the skin adjacent to a wound site, a cable for attachment to opposite ends of an incision's longitudinal axis which is coupled to the applicator head, a motor means for driving the cable in linear oscillations in opposite directions through alternating half cycles of a predetermined span, and an actuator means for regulating the timing and breadth of the predetermined span of each half cycle.

  • Patent number: 5511549
    Abstract: The present invention is directed to a method for radiation beam therapy delivery system normalization and dose calibration. A prescribed treatment plan is compared to a database of pre-existing and pre-calibrated treatment plans. Upon existence of a matching plan, appropriate calibration factors are assigned to the delivery system monitors according to the pre-existing plan. Variations in delivery system operation are corrected by independent correction of all delivery system monitors established by standard relative calibration taken prior to patient treatment. The advantages of the present invention are particularly significant for proton therapy facilities containing a plurality of delivery systems. The method permits a prescribed treatment to be administered with accuracy not only at the station associated with the initial treatment planning, but at any available delivery station.
