Self-Adherent Implants with Release Liner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for securing medical implants, such as surgical meshes, require the use of fasteners or adhesives, which increase surgical procedure duration and risk premature adherence to unintended surfaces.
Innovation Solution
Self-adherent medical implants with an adhesive on their surface and a release sheet to prevent premature adherence, packaged in a way that allows controlled activation of the adhesive at the implantation site, eliminating the need for fasteners and reducing unintended adhesion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fasteners (tacks or staples) are used to secure implants, then the implant can be anchored to tissue, but the surgical procedure duration increases and the implant is only supported at penetration points
Solution Approach 1:
The patent removes fasteners entirely from the implant system, extracting the anchoring function and replacing it with a self-adherent coating that provides continuous surface attachment without requiring separate fastening components or manipulation tools
Solution Approach 2:
The implant is coated with adhesive material that enables self-adherence to tissue upon contact, eliminating the need for external fastening devices or complex manipulation tools, thereby reducing surgical procedure duration while maintaining reliable anchoring
2Reliability
If adhesives are applied to implants immediately prior to implantation, then the implant can adhere to target tissue, but the adhesive may interact with unintended surfaces during handling
Solution Approach 1:
The patent segments the adhesive system into two separate components: the adhesive-coated implant and a release liner. This separation allows the adhesive to be protected during handling and storage, preventing premature adhesion to unintended surfaces while maintaining readiness for implantation
Solution Approach 2:
A release liner acts as an intermediary barrier between the adhesive-coated implant and unintended surfaces during handling. The release liner prevents harmful premature adhesion interactions while allowing the adhesive to function properly when the liner is removed at the implantation site
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution reduces surgical complexity and minimizes the risk of premature adhesion to non-target surfaces, allowing for efficient and precise implantation with reduced procedural time.
