Abstract

A modular portable patient communicator (PPC) provides for communications with a patient implantable medical device (PIMD) and connectivity with a central authority (CA) via an unsecured network. Medical firmware and a radio facilitate wireless interrogation of the PIMD and acquisition of PIMD data. A universal communications port facilitates mechanical and signal connectivity with one or a multiplicity of disparate detachable modules, some of which provide the PPC with an external communications facility and have disparate communication protocols. The PPC is devoid of an external communications facility other than the radio and universal communications port. Life critical network software is executed in cooperation with an attached module to cause the PPC to transmit a request to a network access facility for a connection to the unsecured network, authenticate the PPC to the CA, and facilitate secured communication between the PPC and CA upon successful PPC authentication.
