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.

Transvascular access devices and methods for transvascular access are provided. The transvascular access devices can include a guidewire lumen and a guide tube and stylet disposed in a second lumen. The guide tube can be used to control the orientation of the stylet and provide additional support for the stylet. The methods include providing a second entry point in a vessel of a patient remote from a first entry point. A vascular catheter can enter the vascular system of a patient at a first entry point and be advanced to a second entry point. A guide tube can be advanced out the second lumen of the vascular catheter with a stylet advanced out of the guide tube to pierce the vessel wall and skin of the patient at the second entry point. A catheter can be introduced to the vascular system at the second entry point.
