  • Patent number: 8344526
    Abstract: Energy harvesting systems are described in which electroactive materials, such as dielectric elastomers, may be utilized to absorb the shocks, bumps, and vibrations from the road or path to generate energy which is captured and stored for use in the vehicle to provide additional power for any number of uses. Other devices and systems, such as household appliances which dissipate vibrational energy, may also incorporate any number of the dielectric elastomer generators.

  • Patent number: 8088122
    Abstract: Optical ear infection treatment device and methods are described where an LED and optical light pipe are used to deliver the light from the LED to the middle ear of a patient to reduce bacterial growth and/or eliminate bacteria. Typically, the device is placed in the ear and then activated by the user by pressing an activation button. Once activated the control electronics will turn on the LED and perform a treatment. The most basic treatment mode comprises turning on the LED at maximum power for a predetermined period, e.g. 30 minutes, 60 minutes. When the preset duration is completed, the device will notify the user by an audible beep or vibration that the treatment is complete. Once completed the user can remove the device, the treatment could be repeated once a day or for extreme cases multiple times during the day.

  • Publication number: 20110239372
    Abstract: Embodiments of the technology provide a personal support device for provision of therapeutic support to a portion of a body resting thereon and methods associated with the device. Device embodiments include a substrate having an array of pressure-distributing element host sites, and a population of volumetrically-incompressible pressure-distributing elements at the host sites to form an array of pressure-distributing elements. A therapeutic surface overlays the pressure-distributing elements, and provides an interface between the array of pressure-distributing elements and an aspect of the body portion in contact with the therapeutic surface. The device is configured to form a supportive site within the therapeutic surface that is conformative to the aspect of the body portion in contact with the therapeutic surface when the body part is lying thereon.

  • Publication number: 20110032103
    Abstract: A motion detection system for detecting movement and/or breathing from a subject, e.g., for preventing SIDS, can incorporate a sensor in communication with a fluid-filled chamber while optionally combining audio and/or video monitoring systems. The sensor module may have a housing which can be attached, e.g., to an article of clothing worn by the subject. The sensor may be entirely enclosed within the housing which may also be filled with a vibrationally transmissive medium which transmits movements from the subject such that these signals impinge upon the sensor which captures these signals (or the absence of these signals) for processing and possibly alerting a parent or caretaker.

  • Patent number: 7882842
    Abstract: An airway implant device for maintaining and/or creating an opening in air passageways is disclosed. Methods of using the device are also disclosed. The airway implant device comprises a deformable element to control the opening of an air passageway. Preferably the deformable element is an electroactive polymer element. Energizing of the electroactive polymer element provides support for the walls of an air passageway, when the walls collapse, and thus, completely or partially opens the air passageway. Some embodiments of the invention include a sensor capable of sensing the possible occurrence of an apneic event and activating the deformable element of the airway implant device. Methods of treating airway disorders such as sleep apnea and snoring with the airway implant device are disclosed herein.

  • Publication number: 20100318088
    Abstract: Methods and devices for deploying biological implants are disclosed. The biological implants can include orthopedic, multi-component ankle implants. The target site can be prepared by fixing a rigid, alignable guide or jig with saw holes to the bone(s). Saws configured to fit through the saw holes can then be inserted through the saw holes to cut the bone(s). The jig can then be removed. Slidable implants can be positioned. Implants needing to be forced into place can be attached to elongated members to gently hold the implant and to provide a non-implant surface on which to apply the force.

  • Publication number: 20090259093
    Abstract: A biologically implantable artificial sphincter system and methods of using the same is disclosed. The artificial sphincter system disclosed herein comprises a sphincter band and a piezoelectric element, both of which are adapted and configured for coordinated operation to open and/or close a body cavity. The artificial sphincter systems are useful in the treatment of urinary incontinence, fecal incontinence, and reflux disorders. The implanted artificial sphincter can also provide a signal to the recipient to urinate or defecate.

  • Publication number: 20090069866
    Abstract: An implant testing device and a method of detecting an airway implant are disclosed. The testing device detects the presence of the implant within a patient's body and can be used to determine its location. The testing device also provides an indication of proper function of the implant electronics. A detector circuit of the testing device generates an output signal representative of proximity of the airway implant. A processing circuit receives the output signal and determines proximity of the implant based on one or more detection thresholds. The processing circuit also provides a visual and/or audible alert. In some embodiments, the processing circuit varies the flash rate of one or more light emitting diodes and/or the pitch of an alert tone based on proximity of the implant. Various embodiments of the testing device are adapted for handheld use and can include a handle, elongated portion, and detector element.

  • Publication number: 20080027423
    Abstract: Systems for the treatment of nasal tissue, particularly the nasal turbinates, are described. One method for reducing the size of the inferior nasal turbinate is to apply ultrasound energy to the tissue regions beneath the surface of the turbinate tissue. One instrument may be used to deliver ultrasound energy and provide an infusion or injection of a fluid directly into the turbinate being treated, e.g., to bulk up the size of the turbinate to ensure that the ultrasound energy is properly delivered directly into the intended turbinate tissue. Fluids containing anesthetics, fluids infused with analgesics, etc. may be used for pain management while other medications, such as non-steroidal drugs, steroidal drugs, anti-inflammatory drugs, anti-histamines, anti-bacterial drugs, etc., can also be used. Such assemblies can also be utilized with other instruments as a system. For example, such a probe can be used with nasal speculums or imaging instrument in treating tissue.
