Treating tissue pulsed energy using high-voltage catheters

This invention describes a flexible catheter designed to deliver powerful, very short electrical pulses (from microseconds down to picoseconds) directly to tissue inside the body. It works by sending high-voltage electricity through special conductive layers within the catheter, which are specifically built to prevent electrical arcing. The claims narrow the invention to a method using pulses greater than 0.1 kV, applied through a catheter with at least two conductive layers, one of which is made from braided or woven filaments.

Why it matters: The rapid clinical adoption and refinement of pulsed field ablation (PFA) techniques since 2023 have intensified the need for robust, arc-resistant catheters. This invention's focus on specific conductive layer designs to prevent arcing directly addresses a key challenge in expanding PFA applications.
