GALVANOSTATIC METHOD OF MICROBE REMOVAL FROM METAL ORTHOPEDIC DEVICES
20230051427 · 2023-02-16 ·

A system and related method for eliminating microbes from a metal orthopedic appliance includes a counter electrode and working electrode used for applying treatment, and a reference electrode used for monitoring safety parameters. The working electrode is the implanted appliance. Electrical current is applied between the counter electrode and the working electrode to create electrochemical current through the system and create electrochemical reactions on the surface of the working and counter electrode. The chemical species created at the working electrode provide a mechanism to disrupt and kill microbes on that surface, including bacterial biofilms commonly found on infected orthopedic implants. Circuitry connected to the electrodes keeps the applied current constant and allows the voltage between the working and counter electrode to vary. The reference electrode monitors the voltage at the working electrode in order to provide feedback to a processor as part of a feedback mechanism. The processor is programmed with software logic, preventing the voltage from drifting to ranges that correlate with metal immunity or corrosion regions by limiting or altering the applied current.

Methods, apparatuses, and systems for inductive heating of foreign metallic implants

Methods, apparatuses, systems, and implementations for inductive heating of a foreign metallic implant are disclosed. A foreign metallic implant may be heated via AMF pulses to ensure that the surface of the foreign metallic implant heats in a uniform manner. As the surface temperature of the foreign metallic implant rises, acoustic signatures may be detected by acoustic sensors that may indicate that tissue may be heating to an undesirable level approaching a boiling point. Once these acoustic signatures are detected, the AMF pulses may be shut off for a time period to allow the surface temperature of the implant to cool before applying additional AMF pulses. In this manner, the surface temperature of a foreign metallic implant may be uniformly heated to a temperature adequate to treat bacterial biofilm buildup on the surface of the foreign metallic implant without damaging surrounding tissue. The AMF pulse treatment can be combined with an antibacterial/antimicrobial treatment regimen to reduce the time and/or antibacterial dosage amount needed to remove the biofilm from the metallic implant.
