In smart minimally invasive devices, signal transmission and supply of power to the distal end require many thin and fragile wires in order to keep the catheter slim and flexible. We replaced electrical wires by optical fibers and show signal transfer of synthetic aperture ultrasound images as well as photo-voltaic conversion to supply all electronics The absence of conductors provides both intrinsic galvanic isolation and magnetic resonance imaging (MRI) compatibility. The simple and cost-effective design may be pivotal for translation of these advanced devices into the clinic.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
