Title: INTERVENTIONAL INSTRUMENT COMPRISING AN ULTRASOUND TRANSDUCER
Abstract:
The invention relates to an interventional instrument like a catheter comprising an ultrasound unit (41) and a rotation unit (5) for rotating the ultrasound unit, wherein the rotation unit comprises an actuation element (8) being an electroactive polymer or a one-way shape memory alloy for actuating the rotation of the ultrasound unit. Since the rotation unit comprises, as an actuation element for actuating the rotation of the ultrasound unit, an electroactive polymer or a one-way shape memory alloy, the rotation unit with the actuation element can be very compact and small.
