Sinus Ostia Neuromodulation for Chronic Sinusitis Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for chronic sinusitis, including pharmacotherapy and surgical interventions, are either temporary or fail to adequately address the underlying cause, leading to suboptimal efficacy and significant side effects.
Innovation Solution
A treatment device delivering energy to target sites within the nasal cavity, such as sinus ostia and cavity walls, to therapeutically modulate neural structures associated with chronic sinusitis, specifically parasympathetic nerves, reducing hyperactive mucosal secretions and soft tissue engorgement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pharmacotherapy is used to treat chronic sinusitis, then sinus ventilation is improved, but long-term side effects and suboptimal efficacy occur
Solution Approach 1:
The patent replaces pharmacological therapy with a mechanical/physical intervention - radiofrequency energy delivery through an end effector. This substitutes chemical-based treatment with a physical energy-based treatment that directly modifies neural tissue to reduce hyperactive mucosal secretions and soft tissue engorgement, thereby avoiding long-term pharmaceutical side effects while maintaining therapeutic efficacy.
Solution Approach 2:
The patent applies controlled thermal energy (radiofrequency) to change the physiological state of neural tissue. By delivering specific energy parameters (temperature, power, duration) to targeted neural structures, the treatment modifies neural signaling to reduce autonomic dysfunction, achieving sustained symptom relief without the cumulative side effects of long-term medication.
2Reliability
If surgical intervention is used to treat chronic sinusitis, then sinus opening is achieved, but risks and complications increase
Solution Approach 1:
The patent replaces traditional surgical mechanical intervention with a minimally invasive energy-based approach. Instead of using surgical instruments to physically open sinuses, the system delivers radiofrequency energy through a small end effector to modulate neural tissue, achieving sinus ventilation improvement without the risks of bleeding, scarring, or damage to healthy tissue associated with conventional surgery.
Solution Approach 2:
The patent applies treatment locally to specific neural targets within the sinus cavity rather than performing broad surgical intervention. The end effector delivers energy precisely to neural structures controlling autonomic function, affecting only the localized pathological processes while preserving surrounding healthy tissue, thereby reducing surgical complications.
3Loss of time
If current treatments are applied, then symptoms are temporarily relieved, but underlying causes are not addressed
Solution Approach 1:
The patent performs preliminary identification and targeting of the underlying neural mechanisms before treatment delivery. The system identifies specific neural structures responsible for hyperactive mucosal secretions and soft tissue engorgement, then applies energy modulation to these targets, addressing the root cause rather than merely treating symptoms after they manifest.
Solution Approach 2:
The patent incorporates real-time monitoring and feedback mechanisms to ensure accurate delivery of energy to the intended neural targets. This feedback control allows the system to adjust treatment parameters based on tissue response, ensuring that the underlying neural dysfunction is effectively modified while avoiding damage to surrounding structures, thereby providing sustained relief from the root cause.
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
Minimally invasive and localized energy application effectively treats chronic sinusitis by disrupting neural signals, addressing the underlying cause without the drawbacks of traditional therapies.
Implementation Method 1
The energy delivered to the target site(s) may be sufficient to therapeutically modulate or interrupt neural signals associated with parasympathetic nerves that control autonomic function of the sinuses
Implementation Method 2
The energy delivered to the target site(s) is sufficient to therapeutically treat tissues of interest associated with the sinuses, specifically neural tissue
