Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for identifying implanted medical devices, such as cardiac implanted electronic devices (CIEDs), are time-consuming, unreliable, and prone to misidentification, leading to delays in emergency care due to the need for chest X-rays and manual manufacturer verification.
Innovation Solution
A system utilizing a medical device identifier that transmits electromagnetic signals to implanted devices and analyzes the returned signals using cross-correlation to identify the manufacturer, model, and other device information without programming the device, enabling rapid and accurate identification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If chest X-rays are used to identify implanted medical devices, then device identification can be achieved, but the process becomes time-consuming and delays emergency care
Solution Approach 1:
The patent replaces the mechanical/radiological system (chest X-ray imaging) with an electromagnetic signal-based identification system. The identifier device transmits electromagnetic signals that interact with the implanted medical device's electronic components, causing them to emit characteristic electromagnetic signatures that can be detected and used for identification without imaging
Solution Approach 2:
The patent creates an electromagnetic signal copy or signature of the implanted device's response. By analyzing the characteristic electromagnetic signals emitted by the implanted device when stimulated, the system creates a digital fingerprint that identifies the device manufacturer and type without physically examining or imaging the device
2Measurement precision
If manual manufacturer verification is performed, then accurate device identification can be achieved, but the process is slow and reduces productivity
Solution Approach 1:
The implanted medical device itself provides the identification information through its inherent electronic components. When the identifier transmits electromagnetic signals, the implanted device's circuitry naturally responds with characteristic signals that reveal its manufacturer and model, eliminating the need for external verification processes
Solution Approach 2:
The system uses feedback from the implanted device's electromagnetic response to automatically identify the device. The characteristic signals emitted by the implanted device when stimulated provide immediate feedback about its identity, allowing the identifier to quickly determine manufacturer and model without manual intervention
3Measurement precision
If cross-correlation analysis is used to identify device signals, then identification precision is improved, but the computational complexity increases
Solution Approach 1:
The patent pre-stores characteristic electromagnetic signal patterns from various medical device manufacturers in a database within the identifier. By having reference patterns available beforehand, the cross-correlation analysis can quickly compare incoming signals against known patterns without complex real-time processing, reducing computational complexity while maintaining high identification accuracy
