Abstract: A capacitive transducer is provided. The capacitive transducer includes a plate including a protruding center mass and a substrate with a center depression configured to accept the center mass. The capacitive transducer also includes a first electrode coupled to a non-horizontal edge surface of the center mass and a second electrode coupled to a non-horizontal edge surface of the center depression. The capacitive transducer further includes a third electrode coupled to a horizontal edge surface of the center mass and a fourth electrode coupled to a horizontal edge surface of the center depression. The plate is coupled to the substrate at least along an outer perimeter area of the plate and the substrate.

Abstract: Various methods and systems are provided for a deployable invasive device. In one example, the deployable invasive device has a transducer with a plurality of transducer arrays linked by at least one shape memory material, the at least one shape memory material configured to transition the transducer between a first, folded shape and a second, unfolded shape in response to one or more stimuli. When in the second, unfolded shape, an active area of the transducer is increased relative to the first, folded shape.

Abstract: An ultrasound-enabled invasive medical device and a method of manufacturing the ultrasound-enabled invasive medical device. The ultrasound-enabled invasive medical device includes an invasive medical device, an electrical trace deposited either directly on the surface of the invasive medical device or onto an insulating layer covering at least a portion of the surface of the invasive medical device, where the electrical trace is deposited during an additive manufacturing process. The ultrasound-enabled invasive medical device includes an ultrasound transducer assembly attached to the invasive medical device and electrically connected to the electrical trace, and a transducer support structure attached to the invasive medical device, where the transducer support structure defines a nest that is adapted to receive the ultrasound transducer assembly.
