Modular High-Voltage Bipolar Pulse Generator for Electroporation Applications (Ref.TEC0129)
The use of the technique of irreversible electroporation (IRE) requires the development of high-voltage and high-current generators showing also a high performance and controllability. In clinical applications, it is also required these generators to be compact, light, reliable and with high performance regarding electrical safety.
This novel device is able to generate high voltage pulses (tested with up to 12 kV peak to peak) and current (tested up to 400 A peak to peak), with better performance than current available generators. This means that ablation volumes will be higher than those achieved currently. It also allows better flexibility in the output voltage: bipolar voltage, pulse width (from 1 µs) and number of pulses and pulse trains, which are fully configurable. This has positive implications for clinical treatment.
- Higher voltage and current ratings, enabling larger treated regions in the same procedure. Planar electrodes can be used for improved, controlled and homogeneous treatment.
- It is possible to design operation protocols where short time and fast electric pulses are applied. Therefore, treatment times are significantly shortened.
- The device is more compact and lighter than current ones, because no low-frequency transformer is required.
- Power supply using batteries, leading to improved safety and electric isolation. Compliance with EMC regulations and approval process is simplified.
- Since the control architecture is based on a FPGA, future advanced functions can be implemented such as ECG synchronization, treatments automation.
