Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current implantable cardiac defibrillators (ICDs) for treating arrhythmias, such as atrial and ventricular fibrillation, are associated with pain during defibrillation, and there is a need for minimally invasive treatments that can effectively manage arrhythmias without significant discomfort or recovery time.
Innovation Solution
The development of an implantable cooling device that includes a cooling element, electrodes, a memory, and a processor to monitor patient parameters, apply cooling therapy, and adjust the therapy based on feedback parameters, thereby treating arrhythmias and other conditions like trauma and obesity through temperature modulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If implantable cardiac defibrillators (ICDs) are used to treat arrhythmias, then life-saving efficacy is improved, but patient pain and discomfort worsen
Solution Approach 1:
The patent changes the physical parameter of temperature to treat arrhythmias. By cooling the epicardium to temperatures between 0°C and 40°C, the device terminates arrhythmias without causing the painful effects associated with electrical defibrillation, thus maintaining reliability while reducing harmful factors.
Solution Approach 2:
The patent replaces the electrical shock mechanism of traditional ICDs with a thermal cooling mechanism. This substitution eliminates the painful mechanical/electrical stimulus while achieving the same therapeutic goal of arrhythmia termination through temperature modulation.
2Productivity
If traditional defibrillation therapy is applied, then arrhythmia termination is achieved, but recovery time and treatment costs increase
Solution Approach 1:
The patent employs periodic cooling cycles where the cooling element is activated in intervals to maintain therapeutic temperature ranges. This periodic action achieves sustained arrhythmia termination while allowing tissue recovery between cycles, reducing overall recovery time compared to continuous electrical defibrillation.
3Object-affected harmful factors
If cooling therapy is applied to terminate arrhythmias, then patient discomfort is reduced, but therapy optimization requires complex feedback monitoring
Solution Approach 1:
The patent incorporates feedback mechanisms where sensors monitor physiological parameters (such as electrogram signals or temperature) and provide real-time information to the control system. This feedback enables automatic adjustment of cooling therapy parameters, optimizing treatment while managing device complexity through intelligent control algorithms.
