Tissue Repair Patch Cuff Design for Hernia Placement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgically implanted patches for tissue repair, such as hernia patches, face challenges in accuracy and ease of delivery and placement, as well as providing adequate protection to surrounding tissues during procedures.
Innovation Solution
An implantable medical device with a tissue repair material having two sides and an outer perimeter, featuring a cuff formed from the entire outer perimeter to create a fixation area for joining with patient tissues, and a removable support member for ease of manipulation during implantation, allowing for secure attachment and protection of tissues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional hernia patches with slits and finger pockets are used, then the patch can be inserted through the defect, but the accuracy and ease of delivery and placement is compromised
Solution Approach 1:
The cuff is pre-formed around the entire outer perimeter of the patch, creating a ready-made fixation structure that guides placement. The removable support member is pre-positioned within the cuff to maintain its shape during insertion, ensuring the patch is delivered in the correct configuration for accurate placement.
Solution Approach 2:
The removable support member acts as an intermediary tool that facilitates manipulation of the patch during implantation. It provides a grip point and structural support that makes the patch easier to handle and position accurately, then is removed after placement.
2Reliability
If traditional patches without peripheral fixation structures are used, then the structure is simpler, but the ability to provide protection to surrounding tissues and secure fixation is reduced
Solution Approach 1:
The cuff serves multiple functions: it provides fixation by overlapping onto the patch to create an extended fixation area, protects surrounding tissues during implantation, and serves as a structure to hold the removable support member. This multi-functionality achieves reliable fixation and tissue protection without requiring multiple separate components.
3Ease of operation
If patches without removable support structures are used, then the device is simpler, but the ease of manipulation during implant procedures is reduced
Solution Approach 1:
The support member is designed to be removed after serving its purpose during implantation. It is extracted from the cuff after the patch is positioned, leaving only the cuff and patch in place. This temporary addition provides enhanced manipulability during the procedure without permanently increasing the complexity of the implanted device.
