Pelvic Implant with Localized Biomechanical Properties
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical implants used for treating pelvic organ prolapse do not effectively conform to the varying biomechanical behaviors of different anatomical locations within the body, such as the sacrum, anterior vaginal wall, and posterior vaginal wall, leading to inadequate support and potential complications.
Innovation Solution
A medical implant with distinct portions configured to attach to the sacrum, anterior vaginal wall, and posterior vaginal wall, each with specific biomechanical attributes defined by unique sets of parameters, such as modulus of elasticity and viscoelasticity, to emulate the behavior of each anatomical location, ensuring optimal attachment and support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single uniform implant is used to attach to multiple anatomical locations (sacrum, anterior vaginal wall, posterior vaginal wall), then the implant structure is simple and easy to manufacture, but the implant cannot conform to the varying biomechanical behaviors of different anatomical locations
Solution Approach 1:
The implant is divided into multiple distinct portions (first portion for sacrum, second portion for anterior vaginal wall, third portion for posterior vaginal wall), each with specialized biomechanical properties tailored to its specific anatomical location, allowing the implant to conform to varying tissue behaviors while maintaining overall structural integrity
Solution Approach 2:
Each portion of the implant is constructed with different biomechanical attributes (different moduli of elasticity, viscoelasticity, and strength characteristics) matched to the specific requirements of its target anatomical location, enabling localized optimization of mechanical performance without compromising other regions
2Reliability
If different biomechanical properties are assigned to different portions of the implant to match anatomical locations, then the implant conforms better to tissue behavior and provides improved support, but the manufacturing process becomes more complex
Solution Approach 1:
The implant utilizes composite construction with different materials or material layers for each portion, selecting materials with appropriate moduli of elasticity and viscoelasticity to match the biomechanical characteristics of the sacrum, anterior vaginal wall, and posterior vaginal wall, thereby achieving reliable attachment while managing manufacturing complexity through standardized composite fabrication processes
3Ease of operation
If the implant uses standardized attachment mechanisms for all anatomical locations, then the device is easier to operate and install, but it cannot provide optimized support for each specific location's unique biomechanical requirements
Solution Approach 1:
The implant incorporates dynamic attachment mechanisms that can adapt to the specific biomechanical requirements of each anatomical location during the attachment process, allowing the standardized implant structure to dynamically adjust its mechanical properties and attachment characteristics to match the unique tissue behavior at each site

AI summary
The invention discloses an implant. The implant may include a first flap and a second flap. The first flap may further include a first portion, a second portion and a transition region. The first portion may be configured to be attached proximate a sacrum. The second portion may be configured to be attached to an anterior vaginal wall. The transition region lies between the first portion and the second portion. The second flap may be fabricated such that a portion of the second flap is configured to be attached to a posterior vaginal wall. The implant may be configured such that a value corresponding to a biomechanical parameter defining a biomechanical attribute of the portion of the first flap attaching to the anterior wall is different from a value of the biomechanical parameter defining the biomechanical attribute of the portion of the second flap attaching to the posterior wall.
