Abstract
Systems and methods are disclosed for assessing electrode-tissue contact for tissue ablation. An exemplary electrode contact sensing system comprises an electrode housed within a distal portion of a catheter shaft. At least one electro-mechanical sensor is operatively associated with the electrode within the catheter shaft. The at least one electro-mechanical sensor is responsive to movement of the electrode by generating electrical signals corresponding to the amount of movement. The system may also include an output device electrically connected to the at least one electro-mechanical sensor. The output device receives the electrical signals for assessing a level of contact between the electrode and a tissue.
