Embodiment Construction

[0183] While certain embodiments and examples are described below, this disclosure goes beyond the specifically disclosed embodiments and / or uses and obvious modifications and equivalents thereof. Thus, it is intended that the scope of the present disclosure should not be limited by any particular embodiments described below.

[0184] In some aspects, the present application describes the management of chronic and methods and systems for acute pain conditions. Intermittent or continuous short-term and long-term nerve blockade can be produced with reduced risk of damage to nerve cells by combining with nerve junctions via ion-conducting pathways instead of conventional electrodes without ion-conducting components. Disclosed in some embodiments are systems and electrodes for safely delivering blocked direct current (DC) to neural tissue by delivering cyclic cathodic and anodic currents through highly charged chemical processes. Tissue safety can be maintained by using ionicall...

Abstract

Disclosed herein are systems and methods for nerve conduction block that can involve the delivery of relatively high amounts of charge safely to tissue. Such systems and methods can include control systems for safely monitoring a direct current electrode system, including delivering direct current via an electrode lead to a target tissue of a patient; measuring the driving voltage across the electrode; comparing the driving voltage across the electrode to predetermined threshold range values; measuring the body impedance; determining a voltage drop across the lead from the body impedance measurement; and adjusting the driving voltage to maintain the voltage drop across the lead within a predetermined voltage range.
