Abstract: A remotely programmable medical device having a memory for storing a program, a patient interface (electrodes, syringe, etc.), and a microprocessor for operating the patient interface under the control of the program. The program is constructed by a remote knowledge based analysis tool (database with fuzzy logic), accessible by the medical device over a network such as the Internet. The program, responsive to patient data entered into a client computer on the network, is then transmitted to the medical device as through the client computer to which the medical device is coupled via an interface docking terminal. The remotely programmed medical device is then used on the patient. Transcutaneous electrical nerve stimulation (TENS) devices are preferably programmed to output electrical stimulus signals of alternating high (80-100 Hz) and low frequency (2-5 Hz) with symmetric increase and decrease in waveform amplitude.
