Abstract (en)

[origin: WO9822179A2] Ultrasonically marked c0theter for electrotherapy comprising a piezoelectric transducer (21) mounted onto a catheter and electrically connected to its proximal end with longitudinal conductors. The piezoelectric transducer electrodes are of appropriate thickness and conductivity for the ablation energy. The outside electrode (22) is either in direct contact with the tissue or, (for HF systems), covered with electrically insulating layer that does not impede the transmittal of high frequency waves for electrosurgery. The same conductor within the catheter is used both for ultrasonic guidance purposes and for conveying energy. Ultrasonically marked catheter for electrotherapy improves the guidance of electrosurgical procedures due to the fact that the position of the ultrasonic marker transducer and electrotherapy member are at identical position. This invention represents an essential simplification and therefore reduction in price of the manufacture of the electrotherapy catheter with ultrasonic marking since one single element represents the therapy and the guiding system.
