Abstract
A chamber for testing the reactivity of patient fluids to a metallic implant alloy, such as CoCrMo, and a method of determining the reactivity of the patent to the alloy. A sealed mini-electrochemical cell incorporates the alloy surface as well as reference and counter electrodes coupled to a potentiostat for performing electrochemical measurements of the alloy surface while it is in direct contact with freshly harvested human fluids. Freshly obtained body fluids are thus assessed in terms of their bioelectrochemical reactivity with the alloy surface as a measure of the likely reactivity of the patient to the alloy if it were to be implanted into the patient.
