Solution Overview

Problem

Conventional pelvic reconstructive surgeries for pelvic organ prolapse (POP) are not sustainable and are associated with high rates of recurrence and adverse reactions, particularly when using artificial mesh, which poses safety concerns and complications.

Innovation Solution

A dual-component implant system comprising a polymer mesh design for anterior and posterior vaginal wall prolapse support, featuring specific arm configurations and shapes to provide simultaneous support for multiple pelvic organs, reducing the need for multiple surgeries and minimizing complications by integrating support for bladder, urethra, uterus, intestine, rectum, and anus in a single procedure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If artificial mesh is used for pelvic reconstructive surgery, then short-term success rate and fixation effectiveness are improved, but adverse reactions and complications increase

Engineering Contradiction:
Improveshort-term success rateVSAvoidadverse reactions
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the material parameters from synthetic mesh to biocompatible materials (collagen, polyglycolic acid, polylactic acid) with specific porosity (50-90%) and degradation rates. This transforms the material properties to reduce adverse reactions while maintaining structural support functionality during the critical healing period.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The implant uses composite material structures combining different biocompatible materials with varying degradation rates and mechanical properties. The mesh incorporates collagen fibers with synthetic polymers to achieve optimal balance between initial strength and biocompatibility, reducing complications while maintaining reliability.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If multiple artificial meshes are used for treating multiple pelvic organ prolapses, then comprehensive support is improved, but surgical complexity and number of procedures increase

Engineering Contradiction:
Improvecomprehensive supportVSAvoidnumber of meshes
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs a universal implant system that can address multiple pelvic organ prolapses (anterior, posterior, apical) with a single mesh structure. The mesh incorporates multiple functional zones with different arm configurations that can be selectively positioned to provide comprehensive support for bladder, urethra, uterus, vaginal vault, intestine, rectum, and anus simultaneously.

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

Solution Approach 2:

The patent merges multiple separate mesh components into an integrated single-mesh system that combines anterior and posterior repair functions. The mesh features multiple arms extending from a central body that can be simultaneously positioned to treat cystocele, rectocele, and apical prolapse in one surgical procedure, eliminating the need for separate meshes.

Inventive Principle:
Principle #5Merging (Combining)

3Shape

If conventional pelvic reconstructive surgery is performed, then organ repositioning is achieved, but recurrence rate remains high

Engineering Contradiction:
Improveanatomical positionVSAvoidsustainability
Core Design Contradiction:
ShapeVSReliability

Solution Approach 1:

The patent implements a dynamic implant system where the mesh gradually transitions from providing rigid structural support to allowing natural tissue remodeling. The degradation-based load transfer mechanism dynamically adjusts support levels over time, initially maintaining anatomical position and gradually transferring stress to regenerated native tissues to prevent recurrence.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent performs preliminary reinforcement of weak pelvic floor structures before complete mesh degradation occurs. The slowly degrading mesh provides extended support during the critical tissue regeneration period, allowing new ligaments and muscles to form and gain strength before the implant fully dissolves, thereby preventing recurrence.

Inventive Principle:
Principle #10Preliminary action
