TISSUE CONTACT SENSING USING A MEDICAL DEVICE |
摘要 |
Medical devices and methods for making and using medical devices are disclosed. An example system for sensing tissue contact is disclosed. The system comprises a catheter shaft including a distal end portion. The distal end portion includes a sensing assembly having a plurality of electrodes. The plurality of electrodes includes a current-carrying electrode, a first sensing electrode and a second sensing electrode. The first sensing electrode is positioned a first distance from the current-carrying electrode. The second sensing electrode is positioned a second distance from the current-carrying electrode and the first distance is different from the second distance. The system also includes a controller coupled to the plurality of mapping electrodes. The controller is capable of calculating a parameter based at least in part on the first and the second distances. |
