Abstract:
An ultrasound device including an ultrasonic transducer device having a plurality of transducer elements forming a transducer array is provided. Each transducer element includes a piezoelectric material disposed between a first electrode and a second electrode. One of the first and second electrodes is a ground electrode and the other of the first and second electrodes is a signal electrode. The ultrasound device further includes a cable assembly having a plurality of connective signal elements and a plurality of connective ground elements extending in substantially parallel relation therealong. Each connective element is configured to form an electrically-conductive engagement with respective ones of the signal electrodes and the ground electrodes of the transducer elements in the transducer array. The connective ground elements are alternatingly disposed with the connective signal elements across the cable assembly, to provide shielding between the connective signal elements.
Abstract:
A method and apparatus directed to formation of a connection with an ultrasonic transducer apparatus (UTA) comprising a transducer device having first and second electrodes is provided. The UTA is engaged with an interposer device surface. The interposer device is greater in at least one lateral dimension than and extends laterally outward of the UTA, and comprises at least two laterally-extending conductors. A conductive engagement is formed between the first and second electrodes and respective first ends of the conductors. A connection support substrate is engaged with the interposer device about second ends of the conductors, and includes at least two connective elements for forming a conductive engagement with the respective second ends of the conductors. The UTA is then inserted into a catheter member lumen such that the device plane of the UTA and the at least two connective elements extend axially along the lumen.
