Bio-galvanic metal oxygen cell - for human body implant surgery

An anode of high purity esp. a min. 99.9% Al is placed within the cell, and a porous silver, esp. of sintered powder, cathode forms at least part of the wall of the cell housing. A membrane of either porous or non porous material may be applied to the inner or outer face of the cathode, e.g. a porou...

Zusammenfassung:An anode of high purity esp. a min. 99.9% Al is placed within the cell, and a porous silver, esp. of sintered powder, cathode forms at least part of the wall of the cell housing. A membrane of either porous or non porous material may be applied to the inner or outer face of the cathode, e.g. a porous PTFE membrane with pore size of 1-10 mu on the outer face. A double ended or a multiple cell battery configuration can be used. reliable life is extended up to e.g. 5-10 years due to isolation of oxides from body tissue.
