Solution Overview

Problem

Current therapies for mitral valve regurgitation often face challenges in effectively reducing regurgitation, leading to complications such as volume overload on the left ventricle and pulmonary congestion, and require invasive surgical methods that are painful and risky.

Innovation Solution

A prosthetic mitral valve system and deployment system using multiple catheters and a deployment frame system for percutaneous transcatheter delivery, allowing for precise control and simultaneous movement of catheter components to accurately implant a prosthetic mitral valve that anchors with native mitral valve structures, reducing invasiveness and improving safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional surgical methods are used to treat mitral valve regurgitation, then effective reduction of regurgitation can be achieved, but the procedure becomes invasive, painful, and risky

Engineering Contradiction:

Improveeffectiveness of regurgitation reductionVSAvoidinvasiveness, pain, and surgical risk

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The prosthetic mitral valve system is divided into separate components including an anchor assembly and a valve assembly that can be delivered independently through catheters. This segmentation allows percutaneous delivery of functional components without requiring full surgical replacement, reducing invasiveness while maintaining therapeutic effectiveness.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A deployment frame system acts as an intermediary mechanism that controls the delivery and deployment of catheter-based prosthetic valve components. This intermediary system enables precise positioning and controlled release of the prosthetic valve through percutaneous access, avoiding the need for open surgical procedures while ensuring reliable implantation.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If percutaneous transcatheter delivery is used, then invasiveness is reduced and recovery time decreases, but precise control and accurate implantation become more challenging

Engineering Contradiction:

Improveinvasiveness and recovery timeVSAvoidaccuracy of implantation

Core Design Contradiction:

Object-affected harmful factorsVSManufacturing precision

Solution Approach 1:

The deployment frame system replaces complex manual mechanical manipulation with a structured framework that provides mechanical advantage and controlled movement. This system allows operators to achieve precise positioning of prosthetic valve components through coordinated movement of the frame and catheters, enhancing implantation accuracy despite the constraints of percutaneous access.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The deployment frame system incorporates dynamic elements that allow for adjusted positioning and controlled deployment of the prosthetic valve components. The system can be manipulated to accommodate anatomical variations and achieve optimal implantation positions, maintaining precision while enabling flexible adaptation to different patient geometries.

Inventive Principle:

Principle #15Dynamics

3Ease of operation

If multiple catheters are used for delivery, then control and deployment capability are improved, but device complexity increases

Engineering Contradiction:

Improvecontrol and deployment capabilityVSAvoidnumber of catheters and components

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Multiple catheters are integrated into a coordinated system where they work together through a common deployment frame. The catheters are combined in their functional integration, with each serving a specific purpose (anchor delivery, valve delivery, control) while being managed as a unified system. This merging approach maintains operational control while organizing complexity into a manageable integrated structure.

Inventive Principle:

Principle #5Merging (Combining)
