    Abstract: A device for imaging within a body of a patient is provided. In one embodiment, the device includes a flexible elongate member that can be inserted into the body of the patient. The device also has an imaging assembly that is disposed at and extending a length of a distal portion of the flexible elongate member. The imaging assembly may include an array of imaging elements that may have an outward surface and an inward surface. The imaging assembly may further include an integrated circuit adjacent to the inward surface of the array of imaging elements. The device may further include a conductive plate adjacent to and extending at least a portion of a length of the imaging assembly. The conductive plate may receive heat generated by at least one of the array of imaging elements or the integrated circuit.

    Abstract: The invention relates to a capacitive micro-machined ultrasound transducer (CMUT) cell (6) comprising a cell floor (31) having a first electrode (7); a cell membrane (5) having a second electrode (7′) which opposes the first electrode and vibrates during transmission or reception of acoustic energy; a transmitter/receiver coupled to the first and second electrodes which causes the cell membrane to vibrate at an acoustic frequency and/or receives signals at an acoustic frequency; and an acoustic lens (13), overlaying the cell membrane, and having an inner surface opposing the cell membrane and an outer, patient-facing surface. According to the present invention the acoustic lens comprises at least one layer of a material selected from the group of: polybudatiene, polyether block amide (PEBAX), polydimethylsiloxane (PDMS) and buthylrubber.

    Abstract: The present disclosure advantageously describes ultrasound imaging arrays that comprise ergonomic, non-rectangular shapes, as well as associated systems and methods. Non-rectangular transducer arrays allow for ergonomic probe shapes that improve patient comfort, maneuverability of the ultrasound device, and operator workflow. For example, an ultrasound imaging device can include an array of acoustic elements comprising a non-rectangular perimeter. The array includes a plurality of active elements configured to emit ultrasound energy and receive echoes corresponding to the emitted ultrasound energy, and a plurality of buffer elements surrounding the plurality of active elements at the non-rectangular perimeter of the array of acoustic elements. An edge seal comprising a sealing material is positioned at least partially around the plurality of buffer elements, and a buffer element of the plurality of buffer elements is spaced from at least one other buffer element by the sealing material of the edge seal.

    Abstract: A transducer device includes a transducer array (300) configured on a substrate (312). The substrate is configured to flex in accordance with a surface. The transducer array includes elements for transmitting and/or receiving acoustic energy. A shape sensing optical fiber (314) is disposed within the array and configured to shape sense a position of the elements in the array. Stiffeners (308) are connected to the array and configured to flex in accordance with the surface and provide a limit to an amount of flexure.
