SYSTEM AND METHOD FOR DETECTING ELECTRODE-TISSUE CONTACT |
摘要 |
A system for detecting electrode-tissue contact comprises a catheter having a location sensor and a distal tip electrode. 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 the distal tip and reference electrodes. 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 distal tip electrode if contact of the electrode with tissue is detected. |
