Abstract:
An electromagnetic immune tissue invasive system includes a primary device housing. The primary device housing having a control circuit therein. A shielding is formed around the primary device housing to shield the primary device housing and any circuits therein from electromagnetic interference. A lead system transmits and receives signals between the primary device housing. The lead system is either a fiber optic system or an electrically shielded electrical lead system.
Abstract:
An optical sense signal generator for medical device's having a photonic catheter containing optical conductors conducting light energy in two directions between electronics at a catheter proximal end and electrical stimulation and sensing components at a catheter distal end. An optical unit receives light delivered from the catheter proximal end and transmits a first portion of the light while diverting a second portion of the light. The transmitted light is fed to an opto-electrical converter for conversion into electrical stimulation signals. The diverted light is directed to one or more optical modulators that modulate the diverted light output under an applied electrical signal. An electrical circuit generates electrical sense signals corresponding to one or more sensed physiological conditions and provides the signals to the optical modulator(s). This results in modulation of the diverted light output into optical sense signals that are transmitted to the catheter proximal end.
Abstract:
A method and apparatus for treating rheumatoid arthritis by direct injection of electrically generated gold ions into the patient's joint. The gold ions are electrically generated by anodal corrosion of a gold electrode, such as by passing a constant electric current through the gold electrode which can be a thin wire and which is surgically placed in contact with the arthritic joint. The apparatus comprises a source of direct current including a battery and a constant current generator, a gold electrode connected to the source electrically as an anode and adapted to be placed surgically in operative contact with the arthritic joint, and an indifferent electrode connected to the source electrically as a cathode and adapted to be placed in operative contact with the patient's body spaced from the joint. The entire apparatus can be implanted in the patient's body.
Abstract:
A solid electrolyte primary cell comprising a lithium anode, a chlorine cathode and a lithium chloride electrolyte. A solid lithium element operatively contacts the cathode material, and one form of cathode material in a charge transfer complex of an organic donor component material and chlorine. The organic donor component material can be poly-2 vinyl pyridine. Another cathode material can be formed from liquid chlorine. The surface of the lithium anode element which operatively contacts the cathode material can be provided with a coating of an organic electron donor component material. When the lithium anode operatively contacts the chlorine cathode, a solid lithium chloride electrolyte begins to form at the interface and an electrical potential difference exists between conductors operatively connected to the anode and cathode.
Abstract:
A lithium halogen cell comprising a lithium anode, a solid electrolyte comprising lithium halide, and a cathode comprising a mixture of halogen and activated charcoal.
