Implantable Prosthesis Pockets for Hernia Repair Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing prosthetic repair materials for soft tissue and muscle wall defects, such as hernias, lack efficient deployment and placement mechanisms, leading to difficulties in surgical procedures and potential complications.
Innovation Solution
An implantable prosthesis with a patch of repair fabric featuring pockets for easy deployment and placement, combined with a support member for stability and tissue ingrowth, allowing for effective coverage of defects and reinforcement of soft tissue and muscle walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional prosthetic repair materials are used without deployment mechanisms, then the prosthesis can be simple in structure, but the ease of operation during surgical placement deteriorates
Solution Approach 1:
The prosthesis is divided into multiple functional segments: a body portion for defect coverage and one or more pockets for deployment assistance. This segmentation allows the prosthesis to maintain simplicity in its core repair function while adding localized complexity only where needed for ease of placement.
Solution Approach 2:
The pockets are pre-formed structures that facilitate preliminary actions during surgery, such as finger insertion for positioning or instrument insertion for deployment. This preliminary preparation of the prosthesis structure enables easier surgical placement without requiring complex real-time manipulation.
2Ease of operation
If pockets are added to facilitate deployment, then the ease of operation improves, but the device complexity increases
Solution Approach 1:
The pockets are localized features added only to specific portions of the prosthesis body, rather than complicating the entire structure. This local quality approach allows the prosthesis to maintain overall simplicity while providing enhanced deployability at critical locations.
Solution Approach 2:
The pockets serve multiple functions: they facilitate finger insertion for manual positioning, allow instrument insertion for deployment assistance, and can provide structural support during placement. This multi-functionality justifies the added complexity by delivering multiple benefits from a single structural feature.

AI summary
An implantable prosthesis for repairing or augmenting anatomical defects, including an inguinal hernia. The prosthesis may include a repair fabric having a body portion and a pocket on one side of the body portion to facilitate deployment and/or placement of the prosthesis at the defect site. For some applications, such as a reversible prosthesis, a second pocket may be provided on the opposite side of the body portion. Each pocket may be configured to receive a sufficient length of one or more fingers of an individual for deploying and/or positioning the prosthesis. A support member may be provided to help deploy the repair fabric at the surgical site and/or help inhibit folding or buckling of the repair fabric.
