Patent number: 11918269Abstract: Aspects of the present disclosure are presented for systems and methods for identifying characteristics of a return pad in a monopolar electrosurgical system using contact quality monitoring (CQM) and near field communication (NFC) signals. In some aspects, resistance or impedance materials are sensed that may help identify what kind of return pad is being used, including what is the structure of the pad. In some aspects, NFC signals are used to identify characteristics of the return pad. In some aspects, the grounding or return pad may include two separate materials that form an interconnecting or interwoven mesh and both act as non-active electrodes when both contact the patient. A non-zero impedance may separate conductive lines connecting the two separate materials that may be analyzed to obtain a defining signature about that is linked to structural characteristics about the return pad.Type: GrantFiled: September 5, 2019Date of Patent: March 5, 2024Assignee: Cilag GmbH InternationalInventors: Joshua Henderson, Joshua P.
