Solution Overview

Problem

Existing medical implants, such as pacemakers and neurostimulators, require functional testing of contact electrodes during implantation, necessitating additional specialists in the operating room, leading to complex and costly procedures with potential late detection of malfunctions and resource waste.

Innovation Solution

A packaging system with electrically conductive contact means within the packaging material allows for functional testing of contact electrodes in a sterile packaged state, enabling verification of electrode functionality before implantation without breaking sterility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If functional testing of contact electrodes is performed during implantation, then electrode functionality can be verified, but additional specialists are required in the operating room leading to complex and costly procedures

Engineering Contradiction:
Improveelectrode functionality verificationVSAvoidimplantation procedure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by performing functional testing of contact electrodes before implantation. The packaging system includes contact means that enable testing while the implant is still in its sterile packaging, allowing functionality verification to be completed in advance rather than during the implantation procedure itself.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If functional testing is performed during implantation, then electrode functionality can be verified, but malfunctions are detected very late after the patient has undergone complex operation

Engineering Contradiction:
Improvemalfunction detection timingVSAvoidtime for complex operation
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The packaging system enables preliminary functional testing before implantation by providing contact means within the sterile packaging that allow testing of contact electrodes without breaking sterility. This shifts the testing timing from post-implantation to pre-implantation, preventing late detection of malfunctions.

Inventive Principle:
Principle #10Preliminary action

3Reliability

If functional testing is performed during implantation, then electrode functionality can be verified, but non-functional implants have already been removed from sterile packaging and may have contacted human tissue leading to resource waste

Engineering Contradiction:
Improvefunctional verificationVSAvoidwaste of non-functional implant
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The system enables preliminary testing while the implant remains in its sterile packaging through contact means that penetrate or interface with the packaging without breaking sterility. This allows non-functional implants to be identified and discarded before they leave the sterile environment, preventing waste of surgical resources and potential contamination.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The packaging system acts as an intermediary by incorporating contact means within the sterile barrier. This intermediary structure allows electrical contact with the implant's contact electrodes while maintaining the sterile seal, enabling testing without breaking sterility and without the implant needing to be physically removed from its protective packaging.

Inventive Principle:
Principle #24Intermediary (Mediator)

4Reliability

If additional specialists are required in the operating room for functional testing, then electrode functionality can be verified, but implantation procedures become very costly

Engineering Contradiction:
Improveelectrode functionality verificationVSAvoidimplantation cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The packaging system provides self-service functionality by incorporating the testing capability directly into the packaging structure. The contact means within the packaging enable functional verification without requiring external testing equipment or additional specialist personnel in the operating room, making the process self-contained and cost-effective.

Inventive Principle:
Principle #25Self-service
