Methods and systems are provided for preparing radio-frequency devices for secure distribution. The buffer also includes a tristate inverter to produce output data, at an output, that are logically inverse to the intermediate data if the validation signal is active and having its output at high impedance if otherwise. The logic that implements this technique may be a host bridge within a computer system having multiple CPUs or in a switch or router that interconnects multiple nodes or computer systems. The device may provision the wireless network based on the request for network provisioning associated with the wired network. The distal tip of the marker delivery tube is configured to penetrate the substantially sealed distal end of the obturator so that tissue markers can be delivered while the obturator is in place within the body.
