A radio frequency (RF) ablation system is disclosed including signal generator circuitry and control circuitry. The signal generator circuitry is configured to generate a plurality of RF ablation current signals each having a respective phase and a respective amplitude. The control circuitry is configured to reduce crosstalk between a first RF ablation signal of the plurality of RF ablation current signals and a second RF ablation signal of the plurality of RF ablation current signals by adjusting the respective phase of the first RF ablation signal in relation to the respective phase of the second RF ablation signal such that the respective phase of the first RF ablation signal is different than the respective phase of the second RF ablation signal.

A second capacitor is connected in parallel with the second relays. A connection connects the second contacts to the third contacts. The pulses have amplitudes of at least 2 kilovolts. On activation of the first and second relays the first and second contacts connect and the third and fourth contacts connect, so that the first and second assembly terminals connect. On deactivation of the first and second relays the first and second assembly terminals disconnect.

A system for controlling aspiration of a phacoemulsification probe inserted into an eye includes an anti-vacuum surge (AVS) module, one or more sensors, a vacuum relief valve, and a processor. The AVS module is coupled with an aspiration channel of the probe and is configured to mitigate vacuum surges in the channel by regulating flow via the channel. The one or more sensors are configured to measure fluid parameters in the channel. The vacuum relief valve, which is fluidly coupled with the channel, is configured to controllably relieve vacuum in the channel. The processor is configured to identify a change in at least one of the fluid parameters by reading at least one of the one or more sensors, and, responsively to an identified change in fluid parameters, operate the vacuum relief valve using pulse width modulation (PWM) to maintain a pressure in the channel within a predefined range.

A system for use with multiple electrodes coupled to respective spines of a probe includes multiple switches connected to the electrodes and configured to short different respective first subsets of the electrodes to each other and different respective second subsets of the electrodes to each other per different respective settings of the switches. The system further includes a processor configured to control the switches so as to alternate through the settings and, for each of the settings, cause a power generator to apply a voltage between the shorted first subset and the shorted second subset while the probe is deployed within a body of a subject. Other examples are also described.

Irreversible electroporation with shorted electrodes

A system and method that includes inserting a needle of a phacoemulsification handpiece into an eye of a patient and vibrating the needle in a first trajectory. Matter from the eye is aspirated via an aspiration line while the needle is vibrated in the first trajectory. An indication is received, of a vacuum level in the aspiration line. Determined is, that the vacuum level has changed by at least a preset vacuum level change, and in response vibrating the needle is switched to a second trajectory, different from the first trajectory.

An apparatus includes a body, a shaft assembly, and a visualization assembly. The body includes first and second actuators. The shaft assembly extends distally from the body and includes a rigid proximal portion and a steerable distal portion. The steerable distal portion is positioned distally relative to the rigid proximal portion. The first actuator is operable to drive the steerable distal portion to deflect laterally relative to a longitudinal axis defined by the rigid proximal portion. The steerable distal portion is configured to fit within a nasal cavity of a patient. The visualization assembly is disposed within the shaft assembly. The visualization assembly includes a camera.
