  • Publication number: 20170133994
    Abstract: A method of manufacturing an ultrasound transducer is provided. The ultrasound transducer is activated and the activity across the transducer is measured to determine whether the activity at any area does not meet an acceptance criteria. The transducer is then modified so that the area meets the acceptance criteria. The transducer may be modified with a laser which removes material from the area which does not meet the acceptance criteria.

  • Publication number: 20140135664
    Abstract: An oral device for improving airway patency comprises a base adapted to be held between a patient's upper and lower teeth and a tongue-engaging member. The tongue-engaging member engages the tongue and displaces the tongue anteriorly when the base is held between the patient's teeth. A vacuum is applied through the base and the tongue-engaging member in order to draw the soft palate against a posterior region of the tongue in order to stabilize the soft palate and open or clear the patient's airway.

  • Patent number: 8641707
    Abstract: Medical devices using fluid or cooling fluids having one or more bimaterial valves positioned at each point of flow control to control the flow of a fluid in response to temperature changes. In particular, devices for ablating tissue having multiple ablation elements or cells include one or more bimaterial valves positioned within or near the ablation cells. The bimaterial valves respond to temperature changes by adjusting the flow rate of a fluid through the valve.

  • Publication number: 20120271334
    Abstract: A control system alters one or more characteristics of an ablating element to ablate tissue. In one aspect, the control system delivers energy nearer to the surface of the tissue by changing the frequency or power. In another aspect, the ablating element delivers focused ultrasound which is focused in at least one dimension. The ablating device may also have a number of ablating elements with different characteristics such as focal length.
