Abstract
An in vivo, decomposable medical implant is provided and comprises a metal material that contains, as a main alloying constituent, tungsten or a metal from the group rhenium, osmium, and molybdenum. The method for decomposing the implant, via corrosion in a bio system, includes the step of changing the pH level of the bio system, at least at the site of the implant, from a corrosion-inhibiting level to a corrosion-promoting level.
