Solution Overview
Problem
Current asthma management methods require regular patient compliance with medication and avoidance of triggers, which can be impractical and have limitations, especially with side effects from corticosteroid use and resistance to treatment, necessitating an alternative approach for effective asthma control.
Innovation Solution
A system for controlled delivery of therapeutic energy, such as radiofrequency energy, to lung tissue using a temperature and impedance monitoring system with a user-friendly controller and visual indicators to ensure safe and effective energy delivery during medical procedures, allowing for real-time feedback and fault detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pharmacological management with corticosteroid anti-inflammatory drugs is used for asthma control, then inflammation and airway swelling are reduced, but serious side effects occur and patient compliance becomes difficult
Solution Approach 1:
The patent replaces pharmacological management (chemical system) with an energy delivery system that uses controlled thermal energy to treat airway tissue. The radiofrequency energy delivery system heats airway tissue to specific temperatures to achieve anti-inflammatory effects and reduce airway hyperresponsiveness, substituting drug-based treatment with physics-based energy delivery.
Solution Approach 2:
The energy delivery system is designed to be self-regulating with temperature monitoring and control mechanisms. The system automatically maintains target tissue temperature within a predetermined range through feedback control, reducing the need for continuous physician monitoring and adjustment, thereby improving compliance and reducing harmful effects from uncontrolled drug dosing.
2Duration of action of stationary object
If repeated and regular use of prescribed drugs is required for asthma management, then long term control is achieved, but patient compliance becomes difficult
Solution Approach 1:
The energy delivery system performs preliminary treatment of airway tissue to reduce hyperresponsiveness and inflammation before asthma exacerbations occur. By delivering controlled energy to airway tissue during scheduled procedures, the system creates lasting effects that reduce the need for continuous daily medication, improving long-term control while reducing compliance burden.
Solution Approach 2:
The system changes the physical state of airway tissue through controlled thermal energy delivery, creating permanent or semi-permanent modifications to airway smooth muscle and inflammatory cells. This parameter change (tissue temperature and structural modification) provides sustained therapeutic effects without requiring repeated drug administration.
3Object-affected harmful factors
If high doses of corticosteroid anti-inflammatory drugs are administered, then inflammation is suppressed, but serious side effects require careful management
Solution Approach 1:
The energy delivery system applies thermal energy locally to specific airway tissue regions where inflammation and hyperresponsiveness are present. The temperature monitoring and control system ensures that energy is delivered only to the intended target tissue at controlled temperatures, avoiding systemic side effects while achieving local anti-inflammatory effects through selective tissue heating.
Solution Approach 2:
The system incorporates real-time temperature monitoring and feedback control to maintain target tissue temperature within a predetermined range. This feedback mechanism automatically adjusts energy delivery to prevent overheating and tissue damage, eliminating the need for complex side effect management protocols associated with high-dose corticosteroids.
4Reliability
If stimulus avoidance is implemented for asthma management, then trigger exposure is reduced, but it becomes impractical and not always helpful
Solution Approach 1:
The energy delivery system replaces the behavioral approach of stimulus avoidance with a physiological treatment that directly modifies airway tissue properties. By delivering controlled energy to reduce airway hyperresponsiveness and inflammation, the system addresses the underlying pathology rather than requiring patients to continuously identify and avoid triggers, improving both effectiveness and practicality.
