  • Publication number: 20230033766
    Abstract: An optoacoustic probe for optoacoustic imaging of a volume is provided that includes a housing extending from a distal end operable to contact the volume to a proximal end. The optoacoustic probe includes a light source configured to generate light that is transmitted along a light pathway to generate return signals when the light reacts with the volume, and a transducer assembly including a transducer configured to receive the optoacoustic return signals and an acoustic lens provided over the transducer. The optoacoustic probe also includes a steering assembly coupled within the housing and configured to steer the light pathway to generate the light along the light pathway at different scanning areas of the volume based on the return signals.

  • Publication number: 20190150749
    Abstract: An optoacoustic probe for optoacoustic imaging of a tissue is provided. The probe has a distal end operable to contact the tissue and a proximal end. A transducer assembly is configured to receive optoacoustic return signals. An optical window is configured to carry light along a light path to the tissue. The housing comprises a distal portion that has a probe face that includes an acoustic opening into which the transducer assembly is disposed and an optical opening into which the optical window is disposed. The transducer assembly and the optical window extend proximally from the probe face. A gasket is disposed within the optical opening at the probe face and extends at least partially around the optical window. The gasket is configured to form an optoacoustic barrier to at least partially optically and acoustically isolate at least a portion of the optical window from the housing of the probe.

  • Patent number: 8764750
    Abstract: The present devices, systems and processes can simultaneously reduce a malady of the foot, ankle, and/or lower extremity and provide compression and stabilization through the use of a combined internal fixation device, external fixation device and a lower extremity stabilizing device. The various embodiments of the system are capable of providing adequate compression in the medial, central and/or lateral columns and/or sides of the foot, ankle, and/or lower extremity, as well as treating Charcot neuroarthropathy, fractures, revisional foot and combination of ankle surgeries. The external fixation device and/or lower extremity stabilizer can be removed after a certain period of time, leaving the internal fixation system within the body for prolonged stabilization and maintenance of the arthrodesis site(s).
