Solution Overview

Problem

Existing methods for addressing nasal valve insufficiency, such as surgical interventions and external nasal dilators, are invasive, uncomfortable, and do not effectively reduce airflow resistance, impacting quality of life for individuals with breathing difficulties.

Innovation Solution

A method involving an inflatable balloon and energy delivery member is used to reshape nasal airway tissues by inflating the balloon between the nasal septum and lateral wall, applying energy to deform tissues, and optionally delivering pharmaceuticals to reduce resistance and improve airflow.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If surgical interventions are used to correct nasal valve inadequacy, then structural support and airflow resistance reduction are improved, but invasiveness and post-surgical discomfort increase

Engineering Contradiction:
Improvenasal valve structural supportVSAvoidinvasiveness and post-surgical discomfort
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent replaces traditional surgical mechanical interventions (grafts, sutures, incisions) with a non-invasive energy delivery system. An energy delivery catheter delivers controlled energy (radiofrequency, microwave, ultrasound, or optical) to heat and remodel nasal valve tissues in situ, eliminating the need for surgical implantation while achieving structural reinforcement.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces energy as an intermediary mechanism to indirectly remodel tissues. Instead of directly manipulating tissues through surgical contact, energy delivery serves as a mediator that heats tissues to induce collagen contraction and tissue tightening, achieving structural support without physical surgical intervention.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If external nasal dilators are used temporarily, then ease of application is improved, but effectiveness in reducing airflow resistance deteriorates

Engineering Contradiction:
Improveease of applicationVSAvoidairflow resistance reduction
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent replaces mechanical external dilators with an energy-based tissue remodelling system. Instead of relying on external mechanical forces that provide temporary relief, the energy delivery system permanently remodels nasal valve tissues to reduce airflow resistance, combining the ease of non-invasive application with lasting therapeutic effectiveness.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent performs preliminary tissue remodelling before the actual breathing improvement is needed. By delivering energy to heat and contract collagen fibers in advance, the nasal valve structure is permanently strengthened, providing ongoing airflow improvement rather than temporary mechanical assistance.

Inventive Principle:
Principle #10Preliminary action

3Shape

If invasive surgical methods are used to reshape nasal tissues, then tissue deformation and airflow improvement are achieved, but patient comfort and treatment safety worsen

Engineering Contradiction:
Improvenasal tissue conformationVSAvoidpatient comfort and treatment safety
Core Design Contradiction:
ShapeVSObject-affected harmful factors

Solution Approach 1:

The patent substitutes mechanical surgical reshaping with energy-based thermal remodelling. Energy delivery (radiofrequency, microwave, ultrasound, or optical) heats nasal valve tissues to induce collagen contraction and tissue tightening, achieving shape change without surgical incisions, grafts, or mechanical manipulation that cause patient discomfort and safety risks.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the physical state of nasal tissues through controlled energy-induced heating. By delivering energy to raise tissue temperature to specific ranges (e.g., 60-90°C for collagen contraction), the patent achieves permanent tissue remodelling and shape change without the mechanical trauma of surgery, improving patient comfort and safety.

Inventive Principle:
Principle #35Parameter changes

AI summary

A method for reshaping a nasal airway in a patient involves advancing an inflatable balloon of a reshaping device in an uninflated configuration into a nostril of the patient and between a nasal septum and a lateral wall of the nasal airway. The method then involves inflating the inflatable balloon to an inflated configuration to cause the inflatable balloon to contact nasal mucosa covering the nasal septum and the lateral wall, delivering energy from an energy delivery member attached to or inside of the inflatable balloon, and removing the reshaping device from the nasal airway.
