Abstract
A fully implantable and self-contained device is disclosed composed of a flexible electrode array 10 for surrounding damaged nerves and a signal generator 12 for driving the electrode array with periodic electrical impulses of nanoampere magnitude to induce regeneration of the damaged nerves.
Claims8
An implantable therapeutic device comprising:
- a flexible electrode array for surrounding a nerve in its damaged area;
- circuit means for developing a continuous series of square wave pulses of electrical energy at a predetermined frequency;
- circuit means for stretching each of said square wave pulses.
- circuit means for reversing the polarity of said stretched square wave pulses to provide short duration impulses of electrical energy;
- means for energizing all of said circuit means;
- and
- impedance means for applying a series of said short duration impulses of electrical energy in the nanosecond range to said array to regenerate the damaged area of said nerve.
