Patent number: 11864911Abstract: 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.Type: GrantFiled: November 22, 2022Date of Patent: January 9, 2024Assignee: The Board Of Regents Of The University Of Texas SystemInventors: Rajiv Chopra, David Greenberg, Yonatan Chatzinoff
