Orthopaedic Implant Infection Control Device: US Patent Number 9,616,142: This technology describes a method of reducing or preventing the growth of microbes on the surface of an object, wherein the object is of such material that it can act as a working electrode. The method comprises the steps of providing a counter electrode, and a reference electrode. The object is used as the working electrode. Electrical current is passed through the working and counter electrodes. The current through the counter electrode is varied such that the electric potential of the working electrode is constant relative to the electric potential of the reference electrode. Also described is an apparatus for reducing or preventing microbes on an object using a potentiostatic device.
In the United States, costs exceed $14 billion annually to treat orthopaedic implant infections. Orthopaedic implant infections can be disastrous for patients, as biofilms evade the immune system and are often resistant to conventional antibiotic therapy.
Garwood’s technologies and devices have the potential to reduce patient morbidity and mortality while saving many billions of dollars per year worldwide.
