Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current neurologic and psychiatric treatments are often palliative, invasive, and have limited efficacy, with significant relapse rates and adverse side effects, necessitating the development of non-chemical, non-invasive, and more effective neuromodulatory stimulation methods for treating brain disorders.
Innovation Solution
A non-invasive brain stimulation system using a transcranial magnetic stimulation device that delivers theta burst stimulation with specific pulse parameters, such as 2-4 pulses per burst and a burst repetition frequency of 3-8 Hz, to enhance neuroplasticity and achieve high efficacy in treating psychiatric and neurologic conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chemical treatments are used to treat neuropsychiatric disorders, then symptoms can be reduced, but the treatments are palliative, require lifelong medication, have serious side effects, and do not address the root cause
Solution Approach 1:
The patent replaces chemical treatments with electromagnetic field-based neuromodulation. The system uses transcranial magnetic stimulation (TMS) coils to generate electromagnetic fields that directly modulate neural activity, substituting the chemical mechanism of pharmacology with a physical electromagnetic field mechanism. This substitution eliminates the harmful side effects of chemicals while maintaining therapeutic efficacy through direct neural stimulation.
Solution Approach 2:
The patent employs parameter changes by varying the frequency, intensity, and duration of electromagnetic pulse delivery to achieve different therapeutic effects. The system can adjust stimulation parameters dynamically to optimize treatment effectiveness for different patients and conditions, allowing for personalized therapy that addresses root causes rather than merely suppressing symptoms.
2Reliability
If conventional neuromodulation treatments are used, then brain stimulation can be achieved, but the treatments are invasive and have limited efficacy with high relapse rates
Solution Approach 1:
The patent replaces invasive surgical implantation with non-invasive external electromagnetic field application. The TMS device places coils on the scalp to deliver electromagnetic fields through the skull, eliminating the need for surgical insertion of electrodes into the brain. This non-invasive approach maintains the ability to modulate neural activity while removing the risks and discomforts associated with invasive procedures.
Solution Approach 2:
The patent uses electromagnetic fields as an intermediary to deliver stimulation to the brain without direct physical contact. The external coils generate fields that penetrate the skull and scalp to reach target brain regions, serving as a non-invasive mediator that transmits therapeutic signals while avoiding the need for surgical intervention or direct tissue penetration.
3Reliability
If theta burst stimulation with specific pulse parameters is used, then neuroplasticity is enhanced and treatment efficacy is improved, but the device complexity increases
Solution Approach 1:
The patent incorporates preliminary action through automated parameter optimization and pre-programmed stimulation protocols. The device includes algorithms that automatically determine optimal pulse parameters based on patient characteristics and treatment goals, reducing the complexity of manual setup. Pre-defined theta burst patterns and stimulation sequences are built into the device, allowing clinicians to initiate complex treatments without manually configuring each parameter.
Solution Approach 2:
The patent employs feedback mechanisms where the device monitors treatment response and automatically adjusts parameters to maintain optimal efficacy. Real-time feedback from physiological sensors and treatment outcome measures allows the system to self-regulate pulse delivery parameters, reducing the operational complexity burden on users while ensuring consistent therapeutic effectiveness.

AI summary
A therapeutic or diagnostic system comprises a non-invasive brain stimulation device (such as a TMS stimulation device) or other neuromodulation device configured to stimulate a patient's brain or nervous system by emitting electromagnetic pulses according to stimulation parameters, such as a pulse frequency or burst repetition frequency or other parameters, that provides surprising improvements in responsiveness and/or may require only a relatively short train of pulses to achieve high efficacy. In particular, stimulation pulses may be delivered at a frequency of between 12 and 40 Hertz with a 3 to 5 ratio as compared with burst repetition frequency, or at other specific patterns within that range. The stimulation parameters may be pre-stored and customized to individual patients, being identified through an automated search routine during which patient feedback is monitored. A user interface may be provided to allow an operator to conveniently select the appropriate parameters for the desired treatment.
