Solution Overview

Problem

Current methods for treating heart valve diseases, such as mitral and tricuspid valve regurgitation, often require cardiopulmonary bypass and are not adjustable, leading to recurring ventricular remodeling and geometric distortion issues.

Innovation Solution

A device with a ring-like structure and elongate members that can be secured to heart valves and geometry, featuring an adjustment mechanism to alter dimensions and lengths, allowing for simultaneous adjustment of the ring and elongate members to improve valve function and heart geometry without cardiopulmonary bypass.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current methods for treating heart valve diseases are used, then valve function can be improved, but cardiopulmonary bypass is required and the treatment is not adjustable leading to recurring ventricular remodeling

Engineering Contradiction:
Improvevalve functionVSAvoidadjustability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The device incorporates an adjustment mechanism that allows the ring-like structure and elongate members to be dynamically adjusted after implantation. This enables the treatment to adapt over time to prevent recurring ventricular remodeling while maintaining improved valve function, resolving the contradiction between reliability and adaptability.

Inventive Principle:
Principle #15Dynamics

2Reliability

If current methods for treating heart valve diseases are used, then valve function can be improved, but cardiopulmonary bypass is required increasing treatment complexity and risk

Engineering Contradiction:
Improvevalve functionVSAvoidtreatment procedure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts the adjustment mechanism from the traditional fixed annuloplasty ring, creating a separate controllable system. This allows the ring-like structure to be adjusted independently after implantation without requiring cardiopulmonary bypass, reducing treatment complexity and risk while maintaining valve function improvement.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If a fixed ring-like structure is used to treat valve annulus, then initial valve function improvement is achieved, but ventricular remodeling recurs over time

Engineering Contradiction:
Improvevalve functionVSAvoidtreatment duration
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The adjustment mechanism transforms the fixed ring-like structure into a dynamic system that can be modified over time. This extends the duration of effective treatment by allowing adjustments to prevent ventricular remodeling recurrence, maintaining valve function improvement long-term.

Inventive Principle:
Principle #15Dynamics

4Reliability

If elongate members are secured to heart geometry, then ventricular remodeling is reduced, but the structure becomes more complex

Engineering Contradiction:
Improveheart geometry stabilityVSAvoiddevice structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The elongate members serve multiple functions: they connect the ring-like structure to the heart geometry to reduce ventricular remodeling, and simultaneously serve as part of the adjustment mechanism. This multi-functionality reduces overall device complexity while maintaining heart geometry stability.

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