Helical Cuff Deployment via Planar-to-Helical Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing implantable cuffs and insertion instruments face challenges in efficiently deploying and securing cuffs to biological structures due to complex shapes and movements, which can complicate procedures and require larger openings in patients.
Innovation Solution
An implant insertion instrument with a body member and retention member that allows for a cuff to transition from a planar to a helical configuration, enabling secure attachment to a biological structure with minimal profile and space requirements, using a pocket and recess system for precise alignment and deployment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing implantable cuffs are deployed in complex shapes with complex movements, then the cuff can be secured to the biological structure, but the procedure becomes complicated and requires larger openings in the patient's body
Solution Approach 1:
The cuff is segmented into multiple expandable cells that can be independently controlled. This allows the cuff to be delivered in a compressed state through a small opening and then expanded segment by segment to wrap around the biological structure, simplifying the deployment process while maintaining secure attachment
Solution Approach 2:
The cuff transitions from a static compressed configuration during delivery to a dynamic expanded configuration at the target site. This dynamic transformation allows the cuff to adapt to the biological structure's shape while being delivered through a minimally invasive approach
2Reliability
If existing implantable cuffs are deployed in complex shapes with complex movements, then the cuff can be secured to the biological structure, but the necessary opening size in the patient's body increases
Solution Approach 1:
The cuff is designed with a nested structure where the expandable cells are collapsed within each other during delivery, similar to a nested doll. This allows the cuff to pass through a small opening in the patient's body and then expand outward to secure around the biological structure without requiring a large initial opening
3Ease of operation
If simple movements and minimal profile are used to deploy the cuff, then the procedure becomes more efficient with smaller openings required, but the cuff must transition from planar to helical configuration
Solution Approach 1:
The cuff utilizes a helical curvature design that naturally forms when the expandable cells are inflated in sequence. This curved configuration allows the cuff to wrap around the biological structure efficiently with simple expansion movements, transforming from a planar delivery state to a functional helical shape

AI summary
An implant insertion system and methods of use of the implant insertion system are disclosed. The implant insertion system includes an implant and an instrument configured to deliver the implant to a biological structure and assist in deploying the implant to the biological structure. The instrument includes a retention member the secures the implant to the instrument and retains the implant in a first configuration. The retention member is movable to decouple the implant from the instrument. The implant is configured to transition from the first configuration to a second configuration, such that in the second configuration the implant is secured to the biological structure.
