Abstract

An apparatus for blocking the electric activity of an area of tissue, comprises circuitry (S) for creating a long non-excitatory electric signal between at least two points (R1, R2) located in the vicinity of a muscle.

Claims

1. Apparatus for blocking the activity of an area of a tissue comprising circuitry for creating a long non-excitatory electric potential between at least two points located in the vicinity of a muscle, of a magnitude and at a timing at which it is unable to generate a propagating action potential.
