摘要：
An electrode catheter and a method for assessing catheter-tissue contact for tissue ablation are disclosed. An exemplary electrode catheter comprises a flexible catheter shaft. At least one piezoelectric sensor is oriented coaxial to the flexible catheter shaft. The at least one piezoelectric sensor is responsive to movement of the flexible catheter shaft 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 piezoelectric sensor. The output device receives the electrical signals for dynamically assessing a level of contact between the flexible catheter shaft and a moving tissue. In another exemplary embodiment, the system may be implemented in a hydrodynamic environment.
