  • Publication number: 20100198305
    Abstract: Techniques are disclosed for detecting a functionality of a medical device implanted within the human body. A testing method includes delivering power to and measuring an electrical response of ion exchange polymer metal composite (IPMC) material that is part of the implant device in a first testing interval. Power can be transmitted at radio frequencies which penetrate tissue such that direct contact with the implant device is not required. Following the first testing interval, the implant can be powered continuously for a predetermined time. The implant can be powered in a second testing interval and the electrical response can again be measured. A functionality of the implant device can be detected based on the electrical response in the first and second testing intervals. The testing method can be practiced in connection with a handheld device, a retainer, or other suitable apparatus.

  • Publication number: 20100049227
    Abstract: Methods and tools are disclosed for inserting an implant device that treats snoring and apnea of a patient by altering the position of a soft palate. Methods and tools can make an incision in patient's soft and hard palate to create a cavity that can house the implant. The tools can have visually observable markings that can be aligned with the incision, thus controlling the depth of the cavity. A needle having an incision edge can be used to make an incision in patient's soft palate. The needle can be bent into a suitable longitudinal shape to allow easier access and visualization of the process. A blade that makes the cavity in the tissue can be housed inside a channel in the needle. The tools may have stoppers to prevent excessive extension and retraction of the blade thus preventing an excessive cavity depth. Some tools may also house the implant device, which may be implanted after the cavity is formed.

  • Publication number: 20090173351
    Abstract: A tongue implant control system and methods for stabilizing the tongue are disclosed. The tongue implant control system includes an implant device and a non-implanted control device in wireless communication. The control device provides an inductive power transfer for operating the implant device. The control device also sends commands for changing a state of the implant device. The implant device includes a flexible portion for attachment to the tongue and to one or more actuators. The one or more actuators may include shape memory material. The implant device detects a command from the control device and powers an actuator based on the command. Optionally, the implant device communicates its operating state to the control device and the control device displays information about the implant device at a user interface.

  • 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.
