Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Implantable medical devices like ICDs often require complex programming that physicians may not fully understand, leading to inappropriate shocks or malfunctions, and existing remote control systems lack sufficient security and reliability, risking unauthorized access and incorrect device management.
Innovation Solution
A system for remotely controlling implantable medical devices that uses biologic identification methods, such as ECG or pulse oximetry, to ensure secure and reliable communication and management, allowing medical experts to access and reprogram devices only when necessary, with robust user identification and confirmation of device ownership.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control capability is added to implantable medical devices, then device management and reprogramming can be performed remotely, but security risks and reliability concerns increase due to potential unauthorized access
Solution Approach 1:
The system performs preliminary identification and authentication of the patient and physician before allowing remote access to device parameters. The identification module verifies patient identity using biometric data, and the authentication module confirms physician credentials, ensuring that only authorized individuals can access or modify device settings before remote control operations commence
Solution Approach 2:
The patent introduces an intermediary authentication system that acts as a mediator between the remote user and the implantable device. This intermediary layer includes identification and authentication modules that verify credentials before allowing communication between the remote control interface and the device, preventing direct unauthorized access while enabling legitimate remote management
2Adaptability or versatility
If complex programming parameters are provided for device customization, then device functionality can be optimized, but physician understanding and correct programming become difficult
Solution Approach 1:
The system enables self-service remote reprogramming where physicians can access and modify device parameters remotely without needing to fully understand all programming complexities. The automated identification and authentication system handles security verification, allowing physicians to perform routine adjustments through a simplified remote interface while maintaining access to comprehensive programming options when needed
Solution Approach 2:
The patent segments the device control functionality into different access levels and operational modes. Basic remote management functions are separated from advanced programming capabilities, allowing physicians to perform simple adjustments remotely while more complex parameter changes require additional authentication or in-person programming, dividing the complex system into manageable operational layers
3Reliability
If biometric identification systems are implemented for security, then unauthorized access is prevented, but power consumption increases
Solution Approach 1:
The biometric identification system operates periodically rather than continuously, activating only during remote communication sessions or when access is attempted. The identification module remains in a low-power state between operations and only consumes significant power during actual authentication events, reducing overall energy consumption while maintaining security
Solution Approach 2:
The patent replaces complex continuous monitoring mechanical systems with simpler electronic biometric verification. Instead of using power-intensive continuous authentication mechanisms, the system uses efficient electronic biometric comparison algorithms that require minimal power, substituting mechanical complexity with streamlined electronic verification processes

Data Source
AI summary
An implantable electrical pacing system provides for a remote determination of the identity of the person in whom the pacing device is implanted. The bases for the remote identification are (1) comingling of (a) biological identification information of the person linked to the pacing device, and (b) information pertaining to the timing of paced heart beats of the person; and (2) the modulation of the timing by a remote source. By utilizing the system to provide for the remote identification of a person-plus-device, one leg of a communication system having enhanced security is realized.
