    摘要： Cardiac apparatus and methods of using such cardiac apparatus are described. In one embodiment, a cardiac apparatus includes a covering that is configured to at least partially encircle a heart with a first portion of the covering adjacent to a second portion of the covering. The cardiac apparatus also includes an electroactive polymer actuator. A first end of the electroactive polymer actuator is coupled to the first portion of the covering, and a second end of the electroactive polymer actuator is coupled to the second portion of the covering. The second end of the electroactive polymer actuator is oriented such that, upon actuation of the electroactive polymer actuator, the second end of the electroactive polymer actuator extends away from the first end of the electroactive polymer actuator to move the second portion of the covering towards the first portion of the covering.

    摘要： 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 processed by a smart mandibular repositioning system for treatment of the obstructive sleep apnea event.

    摘要： 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 includes a deformable element to control the opening of an air passageway and a tether. 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. Also disclosed is an implant for stabilizing the tongue, the implant having an anchoring portion for securing a first end of the implant with the mandibula; a control portion connected with the anchoring portion, configured for selectively activating the implant; a flexible portion connected at its proximal end with the control portion, where the flexible portion has three-dimensional flexibility in a first state and where the flexible portion has a lesser three-dimensional flexibility in a second state, and where the flexible portion is selectively switchable between the first and second state by the control portion; and an anchoring portion for connecting the implant with the base of the tongue connected with the distal end of the flexible portion. Methods of treating airway disorders such as sleep apnea and snoring with the airway implant device are disclosed herein.

    摘要： 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.
