Prosthetic Repair System with Integrated Adhesive Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prosthetic repair systems for anatomical defects, such as hernias, often cause post-surgical pain due to the need for fasteners or transfascial sutures that penetrate tissue or muscle, and they lack efficient methods for secure fixation and tissue integration.
Innovation Solution
A prosthetic repair system comprising an implantable prosthesis with a material delivery device that includes a manifold and delivery conduits to distribute fixation materials, such as adhesives, between the prosthesis and the tissue or muscle wall, facilitating secure attachment and tissue ingrowth without the need for penetrating fasteners, and allowing for the delivery of additional therapeutic materials like antibiotics and growth factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If fasteners or transfascial sutures are used to anchor the prosthesis, then secure fixation is achieved, but post-surgical pain is caused due to tissue penetration
Solution Approach 1:
The patent replaces mechanical fasteners and sutures that penetrate tissue with a chemical bonding system. Adhesive material is delivered through conduits to bond the prosthesis to the tissue wall, substituting mechanical fixation with chemical adhesion to eliminate pain from tissue penetration while maintaining secure fixation.
Solution Approach 2:
The patent introduces adhesive material as an intermediary substance between the prosthesis and the tissue wall. This intermediary creates a bonding interface that secures the prosthesis without direct mechanical penetration of the tissue, thereby eliminating the harmful effect of pain while achieving secure fixation.
2Reliability
If traditional suture or staple methods are used, then secure attachment is achieved, but tissue damage and pain occur
Solution Approach 1:
The patent substitutes mechanical attachment methods (sutures, staples, tacks) with a chemical adhesive bonding system. The adhesive material is delivered through conduits to create a reliable bond between the prosthesis and tissue wall without mechanical penetration, eliminating tissue damage while maintaining attachment security.
Solution Approach 2:
The adhesive material serves as an intermediary bonding agent between the prosthesis and tissue wall, creating a secure attachment interface without direct mechanical contact or penetration of the tissue, thereby eliminating tissue damage while ensuring reliable attachment.
3Adaptability or versatility
If a material delivery device is added to the prosthesis, then therapeutic material delivery is enabled, but device complexity increases
Solution Approach 1:
The patent merges the material delivery device with the prosthesis by integrating conduits directly into the prosthesis structure. The conduits are formed as part of the prosthesis body, allowing adhesive and therapeutic materials to be delivered through the prosthesis itself to the tissue wall, thereby enabling therapeutic delivery while minimizing additional complexity through integration.
Solution Approach 2:
The prosthesis is designed with multi-functionality by incorporating material delivery conduits that can deliver both adhesive material for attachment and additional therapeutic materials for tissue regeneration or infection prevention. This universal design allows a single device to perform multiple functions without requiring separate independent systems.

AI summary
A prosthetic repair system includes a prosthesis for repairing a defect in a tissue or muscle wall. A material delivery device is provided for delivering a material, such as an adhesive material, to a surface of the prosthesis and/or to particular locations between the prosthesis and the tissue or muscle wall to attach the prosthesis to the wall. The delivery device may be coupled to the prosthesis and configured to distribute the material from one side of the prosthesis to an opposite side that is to face the defect. The delivery device may include a manifold and conduits for delivering the material from the manifold to one or more desired locations. The conduits may penetrate into and/or through the thickness of the prosthesis. After delivery and distribution of the material, the delivery device may be removed from the prosthesis and withdrawn from) a patient.
