Electrical Stimulation Systems with Sensors and Feedback    

Patents covering method and electronic components for electrical stimulation systems for biomedical applications. Electrical signals can be continuously adjusted using sensors and feedback mechanisms.


Two major application areas for electrical stimulation are pacemakers, with $5.7bn estimated global market in 2016 and neurostimulation, with an estimated global market growing from $4.5bn in 2013 to 7.8bn in 2018 at a CAGR of 11.6%.

The neurostimulation/neuromodulation medical device market encompasses: spinal cord stimulation devices, deep brain stimulation (DBS) devices, sacral nerve stimulation devices, vagus nerve stimulation devices, and gastric nerve stimulation devices.

The patents cover a multifunctional electrical stimulation system designed for variety of applications, with multiple adjustable, synchronous pulse/signal generators. The signal from the selected generator/s is fed to at least one output stage, where it is processed to produce a high or low voltage or current output of a desired polarity. The output stage is capable of yielding an electrical stimulation signal that is appropriate for its intended application.

The system can incorporate inputs from various sensors and a feedback mechanism for adjusting the output signal depending on one or more simultaneous sensor inputs. The sensors in the system can be physical, chemical, or biochemical/biosensors. The sensors can sense, e.g., current, voltage, magnetic field, impedance, temperature, pH, gas (O2, CO2, etc.), as well as various biochemical substances involved locally in or resulting from the procedure at the site where the signal is administered or at another site.

For example, in the area of neurostimulation/neuromodulation, by measuring changes in a neurotransmitter, a closed-loop system can be provided that can continuously adjust the signal to achieve a desired result.

The pending applications cover:

- datasheets and accompanying description for: a Programmable Pulse Generator Chip, an Evaluation and Prototyping Board, and an Evaluation and Prototyping Kit. The pulse generator chip can be programmed or preset to deliver several simultaneous and synchronous digital pulses utilized to define timing parameters, as well as for system control. This electronic component can be used in multiple applications, in addition to electrical stimulation, including: programmable pulse generators, automatic test equipment, biomedical instrumentation, control systems, etc.

- a system for diagnosis and treatment, incorporating the electrical stimulation system described in the two issued patents.

Primary Application of the Technology

-Neurostimulation/neuromodulation - for treatment of acute and chronic pain syndromes, movement disorders, dystonia and spasticity, epilepsy,neuropsychiatric and neurodegenerative diseases (e.g., Parkinson's disease, Alzheimer's disesase), gastrointestinal modulation, nerve regeneration.
-Cardiac rhythm management
-Bone healing
-Wound healing
-Programmable pulse generators, automatic test equipment, biomedical instrumentation, control systems
-Application requiring mechanical or acoustic waves by applying signal to appropriate transducer, etc.
