Abstract: Methods and devices for performing ablation using spatially multiplexed waveforms are disclosed. The increased efficacy of monophasic waveforms is combined with the reduced side effects of biphasic waveforms by distributing components of the waveform across multiple electrodes. Charge balancing occurs upon completion of therapy delivery within a time period that avoids muscle stimulation, while allowing unbalanced waveforms to be delivered during stimulation.

Abstract: Ablation probes and methods of their use. Example probes include probe circuits configured to provide identifying information for the probe itself. The probe circuits may sense probe usage and/or age to determine probe end of life (EOL). In response to EOL, the probe circuit generates an output indicating EOL. The probe electronic circuit may also be configured to monitor probe usage via impedance or other features, independent of such operation by an ablation pulse generator.

Abstract: Medical systems and methods for making and using medical systems are disclosed. An example may include a catheter, a sensor, and a pump configured to remove contrast from a vascular system. The catheter may have a lumen through which the pump may suction contrast. The sensor may be positioned distal of and upstream of a distal end of the aspiration lumen and the pump may initiate suction through the lumen in response to a value sensed by the sensor reaching and/or going beyond a threshold value. The catheter may include an expandable member configured to expand in response to a value sensed by the sensor reaching and/or going beyond a threshold value. The sensor may be supported by a distal extension of the catheter or an elongate member configured to extend through and/or along the catheter to position the sensor distal of the distal end of the aspiration lumen.
