Pre-cut Pelvic Mesh with Adjustable Appendages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical procedures for pelvic floor disorders such as cystocele, rectocele, and vaginal vault prolapse are lengthy and challenging due to the need for customizing synthetic mesh implants, which can lead to complications like mesh infection and erosion, and require specialized skills, especially when addressing multiple defects simultaneously.
Innovation Solution
A novel implant system comprising a synthetic mesh with longitudinally extendable material, preassembled or pre-cut to accommodate irregular anatomy, featuring adjustable appendages and indicia for trimming, allowing for tension-free repair of cystocele, rectocele, and vaginal vault prolapse without lifting the bladder, and capable of being secured in various anatomical locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If synthetic mesh implants are customized during surgery to accommodate irregular anatomy, then adaptability to patient anatomy is improved, but surgical time and procedure complexity increase
Solution Approach 1:
The mesh implant is pre-cut into a specific shape with predetermined dimensions that can accommodate the majority of pelvic floor defect configurations. This preliminary preparation of the mesh shape before surgery eliminates the need for intraoperative cutting and customization, thereby reducing surgical time while maintaining adaptability to patient anatomy through the pre-designed geometry
Solution Approach 2:
The mesh implant is divided into distinct functional sections: a first section for anterior wall support, a second section for posterior wall support, and optional third and fourth sections for vault support and incontinence repair. This segmentation allows the single pre-cut mesh to address multiple defects simultaneously without requiring separate implants or extensive intraoperative customization
2Adaptability or versatility
If multiple pelvic floor defects are repaired simultaneously using separate mesh implants, then comprehensive repair coverage is improved, but device complexity and surgical difficulty increase
Solution Approach 1:
Multiple functional sections for different pelvic floor repairs are merged into a single integrated mesh implant. The first section addresses anterior wall defects, the second section addresses posterior wall defects, and optional third and fourth sections provide vault support and incontinence repair capabilities. This consolidation reduces device complexity compared to using multiple separate implants while maintaining comprehensive repair coverage
Solution Approach 2:
The mesh implant is designed with multi-functionality to address various pelvic floor defects including cystocele, rectocele, enterocele, vaginal vault prolapse, and stress urinary incontinence within a single device. The different sections of the mesh can be positioned to treat different anatomical locations and defect types, providing universal applicability across multiple pelvic floor disorders
3Ease of manufacture
If square or rectangular mesh configurations are used, then ease of manufacture is improved, but adaptability to irregular pelvic anatomy deteriorates
Solution Approach 1:
The mesh is pre-cut into a specific non-rectangular configuration with curved edges and notches that match the irregular geometry of pelvic floor defects. This preliminary shaping is performed during manufacturing rather than during surgery, maintaining ease of manufacture through standardized pre-cut designs while improving adaptability to irregular pelvic anatomy through the customized geometry
