A scanning cannula for scanning an electrosurgical instrument for electrical insulation defects includes an elongated sleeve having a receiving end, an opposite exit end, and a passageway extending from the receiving end to the exit end. Methods and kits using primers or probes to detect the presence of these ELF3 gene compositions are also provided. The system then forwards the data frames via at least two data paths, each of which leads to a respective egress switching device. The processor is connected to valve assemblies that regulate air flow both into and out of the inflatable members, and is further responsive to a pressure sensor assembly, so as to actively regulate pressure within the inflatable members. Each sensor that receives a query determines if all requirementsconditions are satisfied.
