Abstract: Various stimulation catheters are disclosed to lie along and stimulate tissue in the intrathecal space. The electrodes on the leads are various sizes to conserve the battery as well as allowing a more defined area of stimulation. It may also include multiple channels or passages for delivery of drugs, thermal or photonic energy. The sheath includes a fixing element configured to fix the electrode in place along the tissue.

Abstract: A tissue stimulation system includes an electrode assembly having at least three electrodes spaced to be stimulated in a patient. A programmable stimulator is connected to and provides stimulation pulses to the electrode assembly. A programming data in the stimulator defines, for each of the at least three electrodes, individual stimulation pulses of varying polarity and at least one of amplitude, frequency, pulse width and pulse shape.

Abstract: A method including administering a drug to the patient and positioning a catheter adjacent to the tissue to be treated by the drug. The tissue may then be stimulated using the catheter. The catheter may include one or more contacts or optical parts at the distal end if the catheter stimulation is by electric energy or by photonic energy, respectively. If the catheter includes a passage with one or more ports at the distal end of the catheter, the drug is administered through the passage. Alternatively, drugs may be administered systematically or concurrently with intrathecally administered agents.

Abstract: An electronic tissue stimulator system is provided comprising a plurality of electrodes to be implanted adjacent tissue to be stimulated in a patient. A transmitting means transmits stimulation pulses for stimulating the electrodes and programming data defining which of the electrodes are to be stimulated and the electrical polarity of the electrodes relative to one another. A receiver to be surgically-implanted within the patient which receives the stimulation pulses and the programming data, and delivers the energy in the stimulation pulses to the electrodes as defined by the programming data. Using an internal voltage source, only the programming data need be transmitted which define electrode selection and polarity and stimulation pulse parameters. Physical parameters can be measured and used to modify programming data. Dose periods are defined by programming data and/or a combination of programming data and physical parameter measurements.

Abstract: A catheter electrode assembly having four equally spaced in-line electrodes along the exterior of the sheath at the distal end and are interconnected to terminals at the proximal end by sets of individually insulated stranded stainless steel wire. The catheter electrode assembly is used for spinal cord stimulation and may be connected by a percutaneous extension to the exterior of the body for testing and evaluation. A permanent full length or partial length stiffening wire or a removable stylet may be provided interior the sheath.

Abstract: A single circuit breaker housing containing a circuit breaker to disconnect the line terminal from the load terminal for a current overload and means to disconnect and reconnect the line terminal from the load terminal for power management. The power management means, activated by an internal or external timer or remote modulated signal, may include a switch in series with circuit breaker contacts or fusible element or electromechanical device to set and reset the circuit breaker contacts. The external timer or other remote activation signals are provided via external terminals on the housing or via a wireless or powerline modulated signal. Electro-optical isolator functionally interconnects and electrically isolates the power management means and the circuit breaker.

Abstract: Fuel consumption is estimated by counting the number of cycles of operation of the cylinders of an internal combustion engine and multiplying by a constant representing the fuel consumed for each cycle. Rate of consumption is measured relative to time and distance. The cycles are counted by sensing the ignition spark or revolution of the distributor rotor.

Abstract: A system for controlling a plurality of variable rate consuming units using a unique sequence to optimize the number of units on and the total consumption of the units relative to a target by increasing and decreasing total consumption from a status position in said sequence in response to a comparison of the total consumption of all units with a target and to a comparison of the total consumption with the target minus the differential consumption to the next step from the status position in the unique sequence. The units status and the results of the comparisons address a device storing said unique sequence to provide consumption requested status which may be overridden by a cycling means to provide a minimum and maximum off time and minimum on time demand command status for demand controllable units. A real time clock addresses a storage device to provide command status for time controllable units.
