  • Patent number: 10322063
    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: 9000251
    Abstract: A wound dressing is made of multiple layers and includes a collection chamber that is in fluid communication with a drainage channel. When applied over a wound, the wound dressing provides protection for the wound while allowing air and fluids to evacuate from the wound through the collection chamber and out through the drainage channel. The wound dressing can include a valve that restricts air and fluids from entering the wound, which is beneficial for treating pneumothorax.

  • Patent number: 8957277
    Abstract: Various systems, methods and materials are disclosed that enable efficient delivery of an agent into an adhesively adhered article, in which the agent elicits a desired outcome, on demand. This strategy, though general in scope, is also more specifically described with regard to enabling painless or atraumatic removal of products adhering to mammalian tissues such as skin and hair by suitably exploiting the ingress of an appropriate agent or like fluid. Other techniques and articles that aid in the handling or removal of such adhesive products are also disclosed.

  • Patent number: 8916742
    Abstract: An engineered designed article providing multi-directional support. Portions of three or more overlapping, circular-like bodies are integrated on a flexible planar membrane into products, such as bandages, headgear, tool handles, lumbar pillows, backpacks, cervical supports, and back supports, to offer a multi-directional, (360° quadrant) support or pressure-concentrating area, to enhance specific support at the medial, lateral, inferior and/or superior part of a body part. The article can be made of material that is waterproof, acts as a shock absorber, and provides multi-directional support. Medicaments can be infused into the pressure-concentrating area of the support or into the membrane itself. An aperture for accepting IV needles is also provided.

  • Patent number: 8887732
    Abstract: Method and devices for the prevention and treatment of pressure ulcers are described in which a portable support assembly may be worn by a bed-stricken individual around particular regions of the body where pressure ulcers tend to form. The portable support assembly may generally include one or more individual fluid filled pods which are enclosed entirely within an inner fluid pad localized along a central portion. Both the one or more pods and inner fluid pad are then enclosed entirely by another layer of fluid within an outer fluid pad which extends over the entire assembly. Each of the fluid layers may be secured to an outer shell which is relatively stiffer than the fluid layers and may restrict or limit the expansion or movement of the fluid pods and/or fluid pads.

  • Patent number: 8876777
    Abstract: A bandage can be used to secure a needle to an access site so as to prevent unintended movement or withdrawal of the needle from the access site during administration of a treatment to a patient. After treatment, the needle can be removed by manipulating a portion of the bandage. Another portion of the bandage can be maintained in position over the access site during needle removal and can be used to promote clotting of the site after needle removal. The bandage may include a clotting agent, a hemostasis pad, and/or a clot-promoting structure. Additionally or alternatively, finger pressure can be applied to the access site through the bandage. For example, the bandage may include a viewing window without any adhesive to allow visual monitoring of the access site during treatment. Finger pressure may be applied to the viewing window and thereby to the access site during and after needle removal to encourage hemostasis.
