US 2016/0256218 A1 · Perivascular Electroporation Device and Method for Extending Vascular Patency

Abstract

A system for performing perivascular electroporation of a blood vessel may include a tissue treatment device configured to contact and surround at least part of a circumference of an outer surface of a blood vessel wall and a control device coupled with the tissue treatment device. The control device may include an electric pulse generator and a tissue impedance modulator. A method for performing perivascular electroporation of a blood vessel may involve coupling a tissue treatment device of a perivascular electroporation system with an outer surface of a wall of the blood vessel and delivering electric pulses to an outermost layer of the blood vessel wall, while limiting a depth of penetration of the electric pulses such that they do not reach an innermost layer of the blood vessel wall.
