Flow Rate Verification Monitor for Fluid-Cooled Microwave Ablation Probe |
摘要 |
A microwave ablation system includes an antenna assembly configured to deliver microwave energy from an energy source to tissue and a coolant source operably coupled to the energy source and configured to selectively provide fluid to the antenna assembly via a fluid path. The system also includes a controller operably coupled to the energy source and a piezoelectric transducer operably coupled to the fluid path to detect a force of fluid flow through the fluid path. The piezoelectric transducer is configured to generate a signal based on the detected force of fluid through the fluid path. The controller is configured to control the energy source output based on the generated signal.
