Abstract
Devices and methods for blocking signal transmission through neural tissue. One step of a method includes placing a therapy delivery device into electrical communication with the neural tissue. The therapy delivery device includes an electrode contact having a high charge capacity material. A multi-phase direct current (DC) can be applied to the neural tissue without damaging the neural tissue. The multi-phase DC includes a cathodic DC phase and anodic DC phase that collectively produce a neural block and reduce the charge delivered by the therapy delivery device. The DC delivery can be combined with high frequency alternating current (HFAC) block to produce a system that provides effective, safe, long term block without inducing an onset response.
