Abstract
Flexible catheters adapted to be inserted into a body to deliver high-voltage, fast (e.g., microsecond, sub-microsecond, nanosecond, picosecond, etc.) electrical energy to target tissue may include a plurality of conductive layers, that may be coaxial. These catheters and method of using them to treat tissue are configured to reduce or avoid arcing.
