Disclosed is a modular, expandable measuring device that includes an access-protected area. The trocar portion contains at least a first plurality of locator wires that are movable between a retracted position within the trocar and a deployed position extending radially from the trocar. The multiple-mode modulator is configured to receive a baseband signal, convert the baseband signal to a radio frequency signal, and to process the RF signal according to either a polar mode or a quadrature mode, depending on a time-varying input voltage of the RF signal. The composite material includes a polymer material and inductively-heatable particles. With some exceptions, quantitative PCR assays indicate that the RNases have anti-viral activity against many of these viruses. The port may be accessible while the support member is an extended position.
