Description

DESCRIPTION OF THE DRAWINGS

(1) To better understand the object of the invention, a preferential form of embodiment is represented in the attached figures, subject to accessory changes that do not essentially alter it. In this case:

(2) FIG. 1 represents a general plan view of an autonomous neurostimulation unit, according to the invention.

(3) FIG. 2 represents a section in elevated view, according to indication A:A of FIG. 1.

DETAILED DESCRIPTION OF A PREFERENTIAL EMBODIMENT

(4) Described below is an example of practical, non-limiting, embodiment of the invention. Other modes of embodiment in which accessory changes are introduced that do not essentially alter it are in no way ruled out.

(5) The object of the invention is an autonomous neurostimulation unit comprised of at least a pair of pads (1) each one of which has: A ceramic interior (11), An intermediate layer (12) A conductive alloy coating (13).

(6) The layers of coating (13) are of different materials in each of the pads (1) that form a pair. Each of the materials has different conductivity. This difference of conductivity helps to create the difference of potentials between the two points in the nervous system channel.

(7) From this basic structuring, any embodiments that do not essentially alter, change or modify the proposal are included in the object of the invention and in particular: that the intermediate layer (12) uses approximately 1.99% cobalt (% in weight); that the inner layer (11) uses approximately from 8.33€ to 11.85% phosphorus (% in weight); that the coating (13) uses approximately, 41.39% gold, 2.32% oxygen and 1.35% cobalt (% in weight); that the coating (13) uses approximately 98.60% silver (% in weight).

(8) The rest (% in weight being nickel in all cases.

(9) The materials, dimensions, proportions and, in general, those other accessory or secondary details that do not essentially alter, change or modify the proposal can be variable.

(10) The terms in which this report is drafted are a true and accurate reflection of the object described, and must be taken in their broadest sense and never in a limited way.
