Implantable Medical Device Data Event Parameter Setting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Implantable medical devices face battery depletion and communication issues due to data processing and communication with external circuitry, leading to inefficiencies in energy consumption and communication latency.
Innovation Solution
The implementation of a method to identify a care usage pattern and set a data event parameter, such as a polling interval or time window, based on expected, observed, or current care cycles, to optimize energy consumption, battery delivery capacity, and communication latency by predicting when the device is providing care and communicating with external circuitry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data processing and communication with external circuitry are performed frequently, then diagnostic reporting and care activation are improved, but battery depletion occurs
Solution Approach 1:
The patent implements periodic action by establishing specific polling intervals and time windows for data communication events. The IMD performs data processing and communication at predetermined intervals rather than continuously, with the polling interval configured to balance between diagnostic reporting needs and battery conservation. This periodic operation allows the device to remain inactive during intervals, significantly reducing energy consumption while maintaining necessary monitoring capabilities.
Solution Approach 2:
The patent applies dynamics by making the polling interval configurable and adjustable based on clinical needs and battery status. The system can dynamically modify communication frequency and data processing intensity, allowing optimization between reliability and energy usage. The configurable nature enables adaptation to different patient conditions and battery states, resolving the contradiction through flexible parameter adjustment.
2Loss of time
If data communication events are increased, then communication latency is reduced, but power consumption increases
Solution Approach 1:
The patent resolves this contradiction by implementing periodic communication events with optimized polling intervals. Instead of continuous communication that would minimize latency but maximize power consumption, the system uses timed intervals to initiate data events. This approach accepts some latency tolerance in exchange for dramatically reduced power consumption during communication-inactive periods, while still maintaining timely data transfer when events occur.
Solution Approach 2:
The patent applies parameter changes by making the polling interval a configurable parameter that can be adjusted to optimize the balance between latency and power consumption. The system allows modification of communication timing parameters based on clinical priorities and battery status, enabling dynamic optimization of the latency-power tradeoff through parameter adjustment rather than fixed operation.
