Solution Overview

Problem

The misuse of therapeutic coatings on medical implant devices due to improper application of coatings or dosages, which can lead to complications such as pain, infection, and other serious side-effects, is a significant challenge in the medical field.

Innovation Solution

A method and system that utilize electronically-readable identifiers to control the delivery of therapeutic coatings, ensuring that only approved coatings and dosages are applied to medical implant devices by switching a coating applicator system from a locked to an unlocked state based on the device's identifier, preventing misuse and ensuring compatibility with specific devices, patients, and environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If point-of-care applicators are used to apply therapeutic coatings to medical implant devices, then the convenience and speed of coating application are improved, but the risk of misuse (improper coating type or dosage) increases

Engineering Contradiction:
Improveconvenience of coating applicationVSAvoidrisk of misuse
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system incorporates an electronic reader that reads identifiers from both the implant device and coating cartridge, compares them against approved combinations in a database, and provides feedback by either enabling or disabling the coating application. This feedback mechanism ensures that only approved coating-implant combinations can be applied, preventing misuse while maintaining ease of operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces an intermediary control system (computing device with database) that mediates between the coating applicator and the implant device. This intermediary verifies the compatibility between coating cartridges and implant devices through identifier matching, acting as a safety layer that prevents improper applications without complicating the user interface.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If identifier verification systems are implemented to prevent misuse, then the safety and reliability of coating application are improved, but the device complexity increases

Engineering Contradiction:
Improvesafety of coating applicationVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses universal identifier tags (RFID or barcodes) that can be read by standard electronic readers, and a database that stores approved combinations. This universal approach allows the system to verify compatibility across different implant devices and coating types without requiring device-specific complex verification mechanisms, thus improving safety while limiting complexity growth.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent replaces manual verification processes with electronic identifier reading and automated database comparison. Instead of requiring users to manually check compatibility charts or labels, the system uses electronic readers and computing devices to automatically verify approved combinations, reducing the complexity of user operations while enhancing safety.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Object-affected harmful factors

If coating application is restricted to approved combinations only, then the harmful effects from misuse are reduced, but the flexibility in coating selection is limited

Engineering Contradiction:
Improveharmful effects from misuseVSAvoidflexibility in coating selection
Core Design Contradiction:
Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary verification by reading identifiers from both the implant device and coating cartridge before allowing application. The computing device checks whether the combination exists in the database of approved combinations beforehand, preventing harmful misuse while still allowing flexibility within the pre-approved options. This preliminary check ensures safety without requiring real-time complex decision-making.

Inventive Principle:
Principle #10Preliminary action

AI summary

Techniques are provided for controlling delivery of a therapeutic coating to a medical implant device. An identifier of the medical implant device may be received. It may be determined, based at least in part on the first identifier, that the first medical implant device is approved to receive the therapeutic coating. A coating applicator system may be switched from a locked state in which it is prohibited from applying the therapeutic coating to an unlocked state in which it is permitted to apply the therapeutic coating. The coating applicator system may, while in the unlocked state, apply the therapeutic coating to the first medical implant device. After the applying of the therapeutic coating, the coating applicator system may be switched from the unlocked state back to the locked state.
