Abstract: A method of diagnosing the occurrence or non-occurrence of a blood vessel blockage or hemorrhage comprises non-invasively applying ultrasound to a location on a patient's body, where the ultrasound is applied in an alternating and pulsed fashion, administering acoustic amplifiers to the patient, monitoring a feedback acoustic response signal of the acoustic amplifiers triggered by the ultrasound, and determining a diagnosis based at least in part on a relationship between an acoustic response signature of the acoustic response signal and a baseline acoustic response signature.

Abstract: Methods and apparatuses are provided for initiating stroke treatment “in the field” and/or during the transport of the patient to a care facility. The capability is provided to adjust automatically to the individual “therapeutic window” for each single patient, which is crucial because of the significant differences in skull morphology between humans of different age, gender and race. Further, the methods and apparatuses are based on the use of non-invasive application of ultrasound, as well as the non-invasive application of ultrasound in combination with an acoustically active agent, such as microbubbles, where stable cavitation of the microbubbles caused by the ultrasound may be relied upon as an underlying mechanism for both the therapeutic application as well as its control.

Abstract: A system and method for examining a patient for an ear disorder. Reflectance ultrasound is applied to a portion of the ear to determine the presence of ear effusion in a middle ear. If ear effusion is present, motion of the tympanic membrane is induced and ultrasound is further applied to the moving tympanic membrane. Echo signals resulting from the ultrasound applied to the moving tympanic membrane are analyzed to obtain information regarding the motion of the tympanic membrane and is used to characterize the ear effusion.

Abstract: A multi-electrode cochlear implant is taught in which approximately twenty or more insulated metal wires are wound around a flexible tube. These wires are held in place with a further layer of dielectric insulating material. The insulation is selectively removed with a laser beam to form electrodes. Two or more layers or valences of wires can be used, with the inner layer of wires terminating distal to the outer layers to provide a stepwise approximation of the tapering of the scala tympani. A shape memory material core may be introduced into the tube, so that the implant will retain an effective shape after implantation. In a preferred embodiment, electrical conductors are connected to the shape memory material to permit the select warming of the shape memory material by the passing of an electric current through it. In an alternative preferred embodiment, the shape memory material is warmed by adjacent heating elements.
