Multi-electrode catheter, system and method |
摘要 |
<p>A system for detecting electrode-tissue contact comprises a multi-electrode catheter having a location sensor and a plurality of contact electrodes. The catheter preferably further comprises a reference electrode that is preferably protected from making contact with tissue. The system further comprises a signal generator to transmit test signals to each of the contact electrodes and to the reference electrode. Tissue contact is detected by comparing the signals across the tip electrode to a return electrode versus the signal across the reference electrode to a return electrode. Ablation energy may be delivered to the contact electrodes if contact of the electrode with tissue is detected.</p> |
