Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
100 words
A flexible porous electrode for ion therapy comprising a substrate of polymer fibers, each of such fibers coated with a thin layer of conductive material to form a conductive mass, said substrate characterized by: a peripheral border in which said fibers are fused into a liquid-impervious and non-conductive mat, whereby conductive solution and conductive fibers are generally contained within said border, and ion concentration and current flow are thereby confined to the area within the periphery defined by said border, and said substrate including a tab portion through which said conductive fibers are adapted for electrical connection to a conductor.
Claim 2
Dependent Claim
100 words

Claim 3
Dependent Claim
18 words
The device as defined in claim 1 in which said electrode is formed as a one piece element.
