Solution Overview

Problem

Current cardiac tissue engineering methodologies are limited by the inability to monitor and control the performance of engineered tissues after transplantation, which hinders effective healing and regeneration post-myocardial infarction.

Innovation Solution

A scaffold device integrating a three-dimensional polymeric element with an electronic element, featuring electrodes with an electrically-isolating layer, allows for monitoring and stimulation of cardiac tissue, as well as controlled drug release, by connecting to a measuring device and controller, enabling real-time feedback and therapeutic interventions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional tissue engineering methodologies are used, then engineered cardiac tissue can be produced, but the ability to monitor and control tissue performance after transplantation is lost

Engineering Contradiction:
Improvetissue performance monitoring capabilityVSAvoidscaffold structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the scaffold structure with electronic monitoring and control elements into a single integrated device. The scaffold incorporates electrodes, sensors, and drug delivery mechanisms directly within its matrix, allowing simultaneous structural support and active monitoring/control of tissue performance post-transplantation.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The scaffold device performs multiple functions simultaneously: providing mechanical support for tissue growth, monitoring electrical activity through integrated electrodes, controlling drug release, and enabling real-time feedback. This multi-functionality eliminates the need for separate monitoring and control systems.

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

2Reliability

If electrodes are fully coated with electrically-isolating layer, then electrical isolation is improved, but electrical contact with tissue for monitoring and stimulation is lost

Engineering Contradiction:
Improveelectrical isolationVSAvoidelectrode contact precision
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The electrically-isolating coating is applied selectively to specific portions of the electrodes rather than uniformly across the entire surface. This allows different regions of the electrode to have different properties: some regions remain coated for electrical isolation, while other regions stay exposed for direct electrical contact with the tissue, enabling both monitoring and stimulation functions.

Inventive Principle:
Principle #3Local quality
