Cardiac Sympathetic Nerve Modulation for Reversible Arrhythmia Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for cardiac dysfunction, particularly ventricular arrhythmias, are either ineffective or have irreversible adverse effects, such as Horner syndrome and anhydrosis, due to the lack of precise neural modulation in the cardiac sympathetic nervous system.
Innovation Solution
Reversible modulation of the neural activity of cardiac-related sympathetic nerves in the extracardiac intrathoracic neural circuit using electrical signals to inhibit nerve conduction, specifically at the ansae subclavia or T1-T2 paravertebral ganglia, to stabilize cardiac electrical and mechanical function.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If surgical resection of stellate ganglion or paravertebral chains is performed to treat ventricular arrhythmias, then arrhythmia control is improved, but irreversible adverse effects such as Horner syndrome and anhydrosis occur
Solution Approach 1:
The patent replaces irreversible mechanical surgical resection with reversible electrical field application. Instead of physically cutting or removing neural tissue, the invention uses electrical fields to temporarily modulate nerve conduction, achieving arrhythmia control without permanent structural damage to the stellate ganglion or paravertebral chains.
Solution Approach 2:
The patent transforms the static, irreversible surgical intervention into a dynamic, reversible process. The electrical field application can be adjusted in real-time, turned on or off, and modified in intensity, allowing the therapeutic effect to be dynamically controlled while avoiding permanent adverse effects on cardiac sympathetic innervation.
2Reliability
If electrical stimulation or transection of paravertebral chain is applied to modulate autonomic imbalances, then arrhythmia reduction is achieved, but permanent neural damage occurs
Solution Approach 1:
The patent replaces mechanical transection or high-energy electrical stimulation that causes tissue damage with a non-invasive electrical field modulation approach. The electrical field is applied at intensities and durations that modulate nerve function without causing structural damage to the paravertebral chain or surrounding neural tissue.
Solution Approach 2:
The patent carefully controls electrical field parameters (intensity, duration, frequency, waveform) to achieve therapeutic modulation of autonomic imbalance while staying below thresholds that would cause neural damage. By optimizing these parameters, the invention achieves arrhythmia reduction while preserving neural tissue integrity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach effectively reduces arrhythmia risk with minimal impact on basal cardiac function, allowing for temporary inhibition that resumes normal cardiac reflex control upon signal cessation, thus avoiding irreversible complications.

AI summary
Modulation, preferably inhibition, of neurosignaling of a cardiac-related sympathetic nerve in the extracardiac intrathoracic neural circuit is effective in stabilizing cardiac electrical and/or mechanical function, thereby providing ways of treating or preventing cardiac dysfunction such as arrhythmias.
