Implantable dosing device
First Claim
1. In an implantable dosing device for the continuous, controllable release of medication in the human or animal body comprised of a medication reservoir of variable volume, a liquid chamber tensionally connected to said medication reservoir, and volume varying means comprised of an ion-exchange diaphragm interposed between two electrodes whereby liquid is transported in an electro-osmotic manner due to an electric field between said electrodes, the improvement wherein said electrodes are hydrogen electrodes connected to each other by way of a line for hydrogen, and wherein said dosing device further includes means for compensating hydrogen losses.

Abstract
The invention relates to an implantable dosing device for the continuous, controllable release of medication in the human or animal body, comprising a medicine reservoir of variable volume and a liquid chamber which is tensionally connected to the medicine reservoir and the volume of which can be varied by liquid which is transported through an ion exchange diaphragm by electro-osmosis due to an electric field between two electrodes. According to the invention, the electrodes in such an implantable dosing device are hydrogen electrodes which are connected to each other by a line for hydrogen, and means are further provided for compensating hydrogen losses.
