John W Keller Jr, William E Bursack, Alan Coombes: Mutually noninterfering transcutaneous nerve stimulation and patient monitoring. Stimtech, Audley A Ciamporcero Jr, May 25, 1982: US04331157 (48 worldwide citation)

Transcutaneous electrical nerve stimulation is applied to the patient, as though electrocardiograph monitoring is not being practiced. The EKG signals are preprocessed through a selective sample and hold module, which performs amplification, comparison with selective frequency and amplitude standard ...

William D Bailey: Disposable electrode. Stimtech, Audley A Ciamporcero Jr, January 6, 1981: US04243052 (44 worldwide citation)

A disposable electrode includes a fabric backing and a conductive mesh layer laminated thereto. A conductive polymer adhesive interfaces the conductive mesh with the skin of the patient. In order to promote uniform current density, connection to external apparatus occurs by means of a stranded wire ...

John W Keller Jr: Electronic pain control with scanned output parameters. Stimtech, Audley A Ciamporcero Jr, July 1, 1980: US04210151 (40 worldwide citation)

A first oscillator dictates the pulse duration and frequency of stimulating signals; the oscillator output wave form is coupled to an output amplifier stage, and thence to the patient. A scanning oscillator provides a substantially linear ramp voltage, which in turn controls pulse duration, pulse fr ...

William D Bailey: Stimulating electrode. Stimtech, Donal B Tobin, January 11, 1983: US04367755 (34 worldwide citation)

An electrode for tissue stimulating applications, such as pain control, includes a conductive flexible pad such as polymer gel, or karaya gum, interfacing with the patient. A backing layer is composed of conductive silicone rubber, has a multiplicity of perforations therethrough, and defines an inte ...

Norman R Hagfors, John W Keller Jr: Electronic tissue stimulator with output signal controls. Stimtech, Audley A Ciamporcero Jr, December 9, 1980: US04237899 (23 worldwide citation)

In a transcutaneous nerve stimulating apparatus, the stimulating pulse wave form is shaped and manipulated to accommodate specific physiological parameters, and to allow multiple non-interfering electrode administrations. The stimulating pulse wave form, of desired pulse rate, pulse duration, and pu ...

Joseph G Bussey: Perioperative application of electronic pain control in combination with anesthetic agents. Stimtech, Audley A Ciamporcero Jr, October 13, 1981: US04294245 (22 worldwide citation)

The patient is prepared for surgery in conventional fashion, but further including the administration of sterile transcutaneous electrodes proximal to the enervation loci of the prospective incision. Electrical stimulation is commenced, an anesthetic agent is administered, and the electrical stimula ...
