Sheet-Like Surgical Implant Delivery With Orienting Deployment Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The delivery and positioning of biologic constructs, such as regenerative tissue matrices and collagen scaffolds, are hindered by the lack of advanced instrumentation, particularly in ensuring the correct side of the implant seeded with cells is facing the tissue during placement.
Innovation Solution
A modular delivery system with a delivery tube assembly and resiliently expandable deployment arms, equipped with a drive mechanism, allows for secure attachment and controlled deployment of sheet-like implants, ensuring correct orientation and positioning within the body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If biologic constructs are delivered using basic instrumentation, then the implant can be placed in the body, but the positioning and alignment precision is insufficient, making it easy to place the implant wrong side down
Solution Approach 1:
The delivery system is divided into distinct functional components: a delivery catheter for navigation, deployment arms for securement, and a deployment mechanism for controlled release. This segmentation allows each component to be optimized for its specific function while maintaining overall system manageability
Solution Approach 2:
The delivery catheter serves as an intermediary device that guides the implant to the target site through the body's natural pathways. The catheter acts as a mediator between the surgeon's control and the implant's final positioning, enabling precise delivery without requiring direct manual placement
2Ease of operation
If the implant is secured to deployment arms and compressed into the delivery tube, then the implant can be delivered through minimally invasive access, but the device complexity increases
Solution Approach 1:
The deployment arms with the attached implant are nested within the delivery catheter in a compact configuration. This nesting allows the entire assembly to be delivered through small incisions or natural body openings, enabling minimally invasive surgery while maintaining the functionality of all components
Solution Approach 2:
The deployment arms are designed to be dynamically configurable - compressed and nested within the catheter for delivery, then expanded outward at the target site for implant deployment. This dynamic transformation allows the system to adapt between delivery and deployment phases, maintaining ease of operation while managing complexity
