Publication number: 20110295100Abstract: In certain variations, methods, systems and/or devices for enhancing conductivity of an electrical signal through a subject's skin using one or more microneedle electrodes are provided. A microneedle electrode may be applied to the subject's skin by placing the microneedle electrode in direct contact with the subject's skin. The microneedles of the microneedle electrode may be inserted into the skin such that the microneedles pierce stratum corneum of the skin up to or through dermis of the skin. An electrical signal passes or is conducted through or across the microneedle electrode and the subject's skin, where impedance of the microneedle electrode is minimal and greatly reduced compared to existing technologies.Type: ApplicationFiled: May 28, 2010Publication date: December 1, 2011Inventors: Anant V.

Publication number: 20110240037Abstract: 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.Type: ApplicationFiled: June 14, 2011Publication date: October 6, 2011Inventors: Anant V. Hegde, Kasey Kai-Chi Li, Phil Houle, Casidy Hallsten, Chris D. Owen

Publication number: 20110180076Abstract: A wearable tissue retention system generally comprises an oral appliance retractably coupled to a covering which is secured to an anterior portion of the tongue. As the subject moves their tongue naturally or sleeps and the tongue becomes hypotonic, the subject's tongue may move posteriorly. As the covering pulls the tongue anteriorly or maintains a position of the tongue, the base of the tongue may be inhibited or prevented from collapsing posteriorly against the pharyngeal tissue walls and thereby allow the subject to breathe normally by automatically increasing the suction pressure on the tongue to maintain securement of the covering to the tongue as the tongue moves posteriorly. The pump and electronics may be comfortably worn directly by the subject to prevent any tubing or wire entanglement.Type: ApplicationFiled: March 10, 2011Publication date: July 28, 2011Inventors: Anant V.

Publication number: 20100331877Abstract: Airflow restriction systems are described herein which may be used to treat various disorders by creating expiratory positive airway pressure while providing for patient comfort regardless of the patient's anatomical variances. Such a device may be removably secured externally over the patient's nose rather than within the nasal passages to increase patient comfort. The restriction device may be secured, e.g., via an adhesive, to the patient and actuated via any number of mechanical or electromechanical mechanisms. Moreover, the restriction device may include one or more sensors to detect the patient's respiration activity such that the device may be actuated to correspond to the patient's exhalation and squeeze or otherwise constrict the nasal passages at least partially by pressing against the exterior surface of the nose to restrict the expiratory airflow.Type: ApplicationFiled: August 6, 2010Publication date: December 30, 2010Inventors: Kasey Kai-Chi LI, Anant V.

Publication number: 20100319710Abstract: Techniques for operating a subcutaneous implant device are disclosed. The implant device can be formed of a non-magnetic material that is compatible with diagnostics such as magnetic resonance imaging (MRI) and can include a rotor element that rotates under the influence of an external magnetic field. The implant device includes a tension relief mechanism for relieving excessive force applied between the implant device and a portion of a patient's tongue. A non-implanted device can include a stator and drive circuitry for generating the external magnetic field. The non-implanted device can receive a user command and can vary the external magnetic field based on the command. When activated by the magnetic field, the implant device can change its operating state to interact with the patient's body.Type: ApplicationFiled: May 21, 2010Publication date: December 23, 2010Inventors: Adam Sharkawy, Koray Sahin, Adrian McVicker, Jon F.
