  • Patent number: 11246799
    Abstract: A device and method are provided for therapy and treatment of biological tissue such as muscle, tendon, and ligament tissue, by use of a device and method in which therapeutic vibrational frequency resonance patterns are transmitted to tissues of a patient. The resonance frequencies originate from many resonance domains, including vitamins, minerals, herbs, amino acids, and fatty acids. Each domain includes therapeutic frequency resonance patterns. These resonance patterns may be passively excited and transmitted to a patient to enhance tissue function, to decrease the normal rehabilitation time of damaged tissue, and provide therapeutic benefits for muscle tissue dysfunction. Therapeutic frequency resonance patterns may also be actively excited by a delivery mechanism that uses electromagnetic or mechanical waves to interact with the device. The actively excited device transmits the therapeutic frequency resonance patterns to the patients for similar enhancements and therapeutic benefits.

  • Patent number: 10016298
    Abstract: A method of detecting detachment of an ostomy device from a patient includes providing, in the ostomy device, a first electrode separated from the patient by an adhesive that attaches the ostomy device to the patient, where a first capacitor is formed between the first electrode and the patient. The method includes applying a signal to an electrical circuit that includes the first capacitor, and detecting changes in a capacitance value of the first capacitor based on frequency responses of the electrical circuit to the signal. The method additionally includes activating an alarm based upon detecting the changes in the capacitance value of the first capacitor.

  • Patent number: 9849210
    Abstract: Disclosed are medical devices, e.g., surgical sutures, surgical staples, surgical pads, surgical meshes, surgical scaffolds etc., and methods of use at a wound in a patient to facilitate the rapid healing of the tissue at the situs of the wound with minimal fibrous tissue formation. The devices are arranged to be brought into engagement with tissue adjacent the wound to close the wound and include a core formed of a piezo-electric material and an outer layer covering the core. The outer layer is platelet derived growth factors. The methods of use of the devices also include applying a local molecular energy production agent to the wound and irradiating the wound with a pulsed infra-red laser beam.

  • Patent number: 9526817
    Abstract: An apparatus for cleansing wounds with means for stressing the wound bed and optionally tissue surrounding the wound, in which irrigant fluid from a reservoir connected to a conformable wound dressing and wound exudate from the dressing are recirculated by a devise for moving fluid through a flow path which passes through the dressing and a means for fluid cleansing and back to the dressing. The cleansing means (which may be a single-phase, e.g. micro-filtration, system or a two-phase, e.g. dialytic system) removes materials deleterious to wound healing, and the cleansed fluid, still containing materials that are beneficial in promoting wound healing, is returned to the wound bed. The means for stressing the wound bed and optionally tissue surrounding the wound promotes wound healing. The dressing and a method of treatment using the apparatus.

  • Patent number: 9445947
    Abstract: An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a healing manner while also limiting the formation of adhesions that would prevent the removal of the dressing. The dressing includes a layer of porous foam material enclosed by sheets of elastomeric material punctuated by a number of appropriately placed holes. Multiple layers of porous foam may also be used. A suction tube connector is provided on an upper surface of a layer of foam for connection to a negative pressure source. At least one layer of foam is enclosed in elastomeric material and is placed in direct contact with the tissue within the open wound. Fluids are drawn by negative pressure through the holes positioned in the elastomeric envelope and through the foam.
