  • Electrode balloon catheter and high-voltage generation processing device
    Patent number: 12599391
    Abstract: An electrode balloon catheter and a high-voltage generation processing device are provided. The electrode balloon catheter includes a balloon, an inner catheter and a shock wave generation component. The balloon is disposed over the inner catheter and radially expands or collapses as a result of filling an inflation fluid therein or evacuating the inflation fluid therefrom. The shock wave generation component includes a flexible circuit layer and an electrode arrangement. The flexible circuit layer is disposed on the inner catheter, and the electrode arrangement is provided on the inner catheter to be located within the balloon. The electrode arrangement is connected to the flexible circuit layer and connected to a high-voltage generation processing device via the flexible circuit layer. The flexible circuit layer enables the electrode balloon catheter to have a reduced passage size closer to the size of a pre-dilation balloon.
