Solution Overview

Problem

Conventional cardiac support devices (CSDs) for treating heart failure are passive and lack active intervention, relying solely on physical constriction without the ability to administer medicine or combine with modern medical treatments, limiting their effectiveness in treating heart diseases.

Innovation Solution

An active hydraulic ventricular attaching support system with a net cover formed by hollow tubes that can be filled with various fluids to provide reactive pressure and allow for direct medication administration through apertures, enabling active physical support and pharmacological intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional cardiac support devices use passive physical constriction, then the device structure is simple, but the treatment effectiveness is limited and cannot provide active intervention

Engineering Contradiction:
Improvetreatment effectivenessVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs a hydraulic system with hollow tubes filled with fluid to provide active ventricular support. The fluid pressure can be adjusted to dynamically support the ventricle, replacing passive mechanical constriction with controllable hydraulic pressure. This allows for active intervention while maintaining structural simplicity through the use of fluid mechanics.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Adaptability or versatility

If conventional CSD relies solely on physical constriction, then the device is easy to manufacture, but it cannot combine with medicine treatment

Engineering Contradiction:
Improvetreatment combination capabilityVSAvoiddevice manufacturing
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent integrates multiple treatment modalities into a single device system. The hollow tube structure serves dual purposes: providing hydraulic support and delivering medication directly to the ventricular wall through integrated drug delivery ports. This multi-functional design enables combined mechanical and pharmacological treatment without significantly complicating manufacturing.

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

Solution Approach 2:

The patent merges the mechanical support function and medication delivery function into a unified system. The hollow tubes that provide hydraulic pressure also serve as conduits for drug administration, combining two separate treatment approaches into one integrated device that simplifies the overall treatment protocol.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If conventional CSD provides passive support, then the device operation is simple, but it lacks adjustable and controllable support

Engineering Contradiction:
Improveoperation simplicityVSAvoidsupport adjustability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent transitions from static passive constriction to dynamic active support by using a fluid-filled hydraulic system. The fluid pressure can be adjusted in real-time to match the patient's cardiac cycle and clinical needs, providing controllable and adaptable support while maintaining ease of operation through external pressure control mechanisms.

Inventive Principle:
Principle #15Dynamics

4Quantity of substance

If conventional CSD uses fiber net constriction, then the device structure is simple, but it cannot deliver high-concentration medication directly to heart tissue

Engineering Contradiction:
Improvemedication delivery capabilityVSAvoiddevice structure
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The patent utilizes the hollow tube structure as a porous or permeable delivery system that allows direct contact between high-concentration medication and the ventricular wall. The tube walls can be designed with controlled porosity to facilitate localized drug delivery while maintaining structural integrity and providing hydraulic support.

Inventive Principle:
Principle #31Porous materials

AI summary

An active hydraulic ventricular attachable support system includes a net cover for surrounding a ventricle and is formed by hollow tubes. All the hollow tubes can completely communicate with each other or form a plurality of independent areas, and the interior of each independent area is intercommunicating, while the independent areas are not communicating with each other. The system as a whole is positioned on the surface of the heart. The hollow tubular structure can be filled with various kinds of liquid of different physical characteristics, and then the corresponding reaction pressure generated can be applied to the ventricle and the surfaces of the heart. The system also can be incorporated with local administration.
