摘要： A method is provided of tissue ablation during a tissue ablation procedure. Ablation energy is applied by using a tissue ablation device to create an ablation at a tissue site. An ablation endpoint at the tissue site is detected by using an ablation endpoint device with one or more sensors that are positioned to monitor the ablation. The one or more sensors are selected from at least one of, a piezoelectric and a silicon MEMS sensor. Upon detecting the ablation endpoint, delivery of ablation energy to the tissue site ceases.

摘要： A system includes an expandable distal end of a catheter and a processor. The expandable distal end has multiple electrodes that are configured to be placed in contact with a tissue in an organ and to apply ablative power to tissue. The processor is configured to, during application of the ablative power, determine whether a physical contact between the electrodes and tissue meets a predefined contact quality, and, if the physical contact of an electrode among the electrodes with the tissue does not meet the predefined contact quality, re-use the electrode for electrophysiological (EP) sensing.

摘要： The present disclosure is directed to measuring impedance across a plurality of electrode pairs. The disclosed systems and methods may simultaneously provide drive signals between electrode pairs and then sense the voltage signals that develop at the electrodes. Digital signal processing may be used to synchronously demodulate the voltage signal at each electrode to determine impedances at the electrodes. Each electrode pair may be driven at a unique frequency to allow for significantly increasing a number of electrode pairs and/or increasing drive current magnitudes. Synchronous demodulation allows the unique frequencies to be detected independent of each other while minimizing crosstalk. Typically, the drive frequencies are made orthogonal by setting the drive frequencies at harmonics of a common base frequency and measuring a response over an integer number of cycles. In an embodiment, quadrature demodulation may occur providing a real component for resistive impedance and an imaginary component for reactive impedance.

摘要： A modular energy system including a header module and a module. The header module includes a display screen for displaying a user interface. The header module is configured to receive data, including safety critical data, from the module, control the display screen to cause the UI to display UI content based on the received data, the UI content including safety critical UI content based on the safety critical data, and transmit the displayed safety critical UI content to the module for verification thereby. The module is configured to confirm whether the transmitted safety critical data coincides with the displayed safety critical UI content. In the event that it is determined that they do not coincide, the header module and/or the module can be configured to stop the function(s) of the module, display an alert on the display screen, and take various other actions.

摘要： A digital measurement system includes an oscillator, a mixer, and a controller coupled to each other. The oscillator provides a reference signal having a second frequency. The mixer generates a down-converted signal based on the output signal and the reference signal. The controller then determines a characteristic of the output signal (e.g., frequency or phase) based on the down-converted signal. An analog measurement system includes a filter having a center frequency, a rectifier, and a controller. The filter filters the output signal and the rectifier rectifies the filtered signal. The controller samples the rectified signal and determines a characteristic of the output signal based on the level of the rectified signal. The reference signal controller may adjust a characteristic of the output signal based on the determined frequency and/or phase of the output signal.
