The pump may further include electrolysis electrodes (240) with-in the first chamber for causing genez'ation of a gas therein and to thereby expand the expandable diaphragm so that fluid is forced from the second chamber into a cannula (120).

Selon linvention, des modes de réalisation dune pompe électrolytique implantable comprennent un premier diaphragme extensible et un second diaphragme flexible, et des première et seconde chambres chacune contenant un fluide, le premier diaphragme extensible séparant les première et seconde chambres et fournit une barrière de fluide entre elles, et la seconde chambre est formée entre le premier diaphragme extensible et le second diaphragme flexible.
