Patents by Inventor Randy Alan Murphy

Randy Alan Murphy has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10716939
    Abstract: An example method includes sending a muscle stimulation current treatment signal to one or more electrodes. The muscle stimulation current treatment signal alternates between on-off states. The method further includes sending, while the muscle stimulation current treatment signal is off, an interferential current treatment signal to the one or more electrodes.
    Type: Grant

  • Patent number: 7747332
    Abstract: An electrical stimulation device is combined with a biologic to increase osteogenesis (i.e., bone healing or bone formation). The electrical stimulation is osteoblastic in that it produces new bone cells and or increases the activity of the existing cells, either osteoblasts or osteocytes. The preferred biologic decreases osteoclastic activity, which is the remodeling of bone usually by destroying the bone. Thus, osteogenesis is maximized by decreasing osteoclastic activity, while at the same time increasing osteoblastic activity. Osteogenesis can also be maximized by combining electrical stimulation with a BMP. Though BMPs are generally considered to increase osteoblastic activity, certain BMPs may have an additive effect to the use of electrical stimulation.

  • Patent number: 6988005
    Abstract: A multi-functional portable electro-medical device that is capable of providing muscle stimulation and interferential current stimulation. The multi-functional portable electro-medical device includes a multitude of safety features which are designed to prevent injury to the user while at the same time to ensure that the portable power electro-medical device is easy to use. The portable electro-medical device can be programmed to impart any combination of wave therapy to the patient.

  • Publication number: 20040015209
    Abstract: A multi-functional portable electro-medical device provides interferential current stimulation to promote bone growth. Two electrical signals are applied to a target area, each electrical signal being formed by a set of two electrode pads. A beat frequency is created at the location the signals intersect with each other. The beat frequency is the difference between the frequencies of the two signals and has an amplitude that is additive and greater than either signal alone. The depth of the interferential signal is increased by increasing the carrier frequency of the signals. The direction of the interferential signal shifts toward the signal having the lower amplitude. The electrical stimulation is used in combination with biologics to further increase bone growth.
