Patent number: 8887732Abstract: 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.Type: GrantFiled: March 4, 2013Date of Patent: November 18, 2014Assignee: PRS Medical Technologies, Inc.Inventors: George Y.

Publication number: 20140249382Abstract: 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.Type: ApplicationFiled: May 13, 2014Publication date: September 4, 2014Inventors: Nikhil BHAT, George Y. CHOI

Patent number: 8813753Abstract: Systems and methods for detecting an obstructive sleep apnea event are disclosed herein. The systems and methods may use an electrical output generating ionic polymer metal composite sensor attached to a region in an airway passage in an oral cavity. The electrical output may be wirelessly transmitted as a signal for indication of an obstructive sleep apnea event. The signal may be further analyzed for treatment of the obstructive sleep apnea event.Type: GrantFiled: September 22, 2008Date of Patent: August 26, 2014Assignee: Medtronic Xomed, Inc.Inventors: Nikhil D.

Patent number: 8555891Abstract: 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: GrantFiled: May 21, 2010Date of Patent: October 15, 2013Assignee: Medtronic Xomed, Inc.Inventors: Adam Sharkawy, Koray Sahin, Adrian McVicker, Jon F.
