Dual Telemetry System for Implantable Neuromodulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current implantable neuromodulation systems have limited range and low data transfer rates, making it impractical to quickly transfer large amounts of data such as MRI and CT images, clinical effects, and other patient-specific data between external systems and the implanted device.
Innovation Solution
Incorporating a dual telemetry system with a low-speed telemetry system for programming data and a high-speed telemetry system for non-programming data, allowing for data transfer rates of 2-800 kbits/sec and 1-50 Mbits/sec respectively, and extending the range beyond the typical 0.1-6 feet to facilitate seamless data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single low-speed telemetry system is used for programming data transfer, then security is maintained and device complexity is low, but data transfer rate is limited to 2-800 kbits/sec making large data sets impossible to transfer
Solution Approach 1:
The patent divides the telemetry system into two separate systems: a low-speed telemetry system for programming data and a high-speed telemetry system for large data sets. This segmentation allows each system to be optimized for its specific function, enabling fast transfer of MRI/CT images while maintaining security for programming operations through the separate low-speed system.
2Length of moving object
If a single telemetry system is used, then device complexity is low, but range is limited to 0.1-6 feet preventing seamless communication across different clinical settings
Solution Approach 1:
The patent implements two separate telemetry systems with different range capabilities. The high-speed telemetry system provides extended range for seamless communication across clinical settings, while the low-speed system maintains secure programming capabilities. This segmentation resolves the contradiction by allowing extended range without compromising security or overwhelming the system with a single complex multi-functional telemetry system.
3Productivity
If high-speed telemetry is implemented for large data transfer, then data transfer rate increases to 1-50 Mbits/sec, but the system becomes vulnerable to spurious/malicious communications
Solution Approach 1:
The patent separates programming operations (requiring security) from large data transfer operations (requiring high speed). The low-speed telemetry system handles programming data with inherent security against spurious communications, while the high-speed system handles MRI/CT images and other large data sets. This segmentation allows high-speed data transfer without exposing the programming interface to security risks.

AI summary
An implantable neuromodulation device includes a plurality of electrical terminals configured for being respectively coupled to a plurality of electrodes; analog output circuitry configured for delivering electrical modulation energy to the electrical terminals in accordance with programming data from a first external control device; a low-speed telemetry system configured for receiving the programming data; a high-speed telemetry system configured for receiving non-programming data from a second external control device; and memory configured for storing the programming data and the non-programming data. The low-speed telemetry system has a data transfer rate in the range of 2-800 kbits/sec, and the high-speed telemetry system has a data transfer rate in the range of 1-50 Mbits/sec. The high-speed telemetry system may have a greater telemetry range than the low-speed telemetry system.
