Solution Overview

Problem

Existing electronic programmers for active implantable medical devices, such as neurostimulators, often fail to ensure that electrical stimulation therapy is correctly programmed to the right patient with the correct device, leading to potential errors due to unfamiliarity with the target patient and device.

Innovation Solution

A portable electronic programmer with a communications module, memory storage, and computer processor that discovers nearby medical devices, extracts patient records, and displays visual identification information and unique device identifiers, allowing users to select the correct device for programming, while maintaining separate partitions for personal and stimulation program data to prevent data contamination and discourage reprocessing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If electronic programmers are used to program medical devices, then programming capabilities are improved, but the risk of programming errors increases due to inability to verify patient-device matching

Engineering Contradiction:
Improveprogramming capabilityVSAvoidprogramming accuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system provides visual feedback by displaying the patient's photograph on the programmer interface during the programming process. This allows the healthcare professional to verify that they are programming the correct device for the correct patient, creating a feedback loop that prevents programming errors.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patient's photograph serves as an intermediary visual element that mediates between the healthcare professional and the programming process. By introducing this visual identifier, the system enables verification of patient-device matching without complicating the programming interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If patient information is stored in medical devices, then data accessibility is improved, but data security and protection from unauthorized reprocessing worsen

Engineering Contradiction:
Improvedata accessibilityVSAvoidunauthorized reprocessing
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by writing the patient's photograph and personal information to the device memory during the initial programming process. This pre-establishes visual and data linkage between patient and device, creating a barrier against unauthorized reprocessing before it can occur.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses visual changes (displaying the patient's photograph) to indicate the status and ownership of the medical device. This visual identifier acts as a protective measure, making it immediately apparent when a device has been improperly reprocessed or is being programmed for the wrong patient.

Inventive Principle:
Principle #32Color changes
