A porous silicon implant (42; 60) impregnated with a beneficial substance, such as a micromineral required for healthy physiology, is implanted subcutaneously and is entirely corroded away over the following months/year to release the micromineral in a controlled manner. In a second embodiment the implant (62) may have a large number of holes (72) which contain beneficial substance and which are closed by bio-errodable doors (76, 78) of different thickness so as to stagger the release of the beneficial substance over time as the doors are breached.
La présente invention concerne un implant de silicium poreux (42, 60) imprégné d'une substance salutaire, telle qu'un microminéral indispensable à la salubrité physiologique. Cet implant qui est implanté sous la peau, subit une érosion par corrosion dans les mois ou l'année qui suit de façon à libérer le microminéral de façon contrôlée. Selon une autre réalisation, l'implant (62) peut comporter un grand nombre de trous (72) qui contiennent une substance salutaire et qui sont fermés par des portes bio-errodables (76, 78) de différentes épaisseurs pour échelonner dans le temps la libération de la substance salutaire au fur et à mesure que les portes se rompent.
