Medical Device Anchoring Apparatus Alignment and Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical device anchoring systems for implantable medical therapy systems face challenges in securely fastening medical devices to the cranium around burr holes, particularly in aligning covers with bases and retaining leads without slippage.
Innovation Solution
The proposed solution involves an apparatus with a base and cover that include alignment marks for easy orientation, and lead retaining members to secure medical device leads. Additionally, a placement tool with a retainer and channel system is used to align and fasten the apparatus to the cranium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If alignment marks are added to the base and cover, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The alignment marks are visual indicators (colored or contrasting markings) placed on the base and cover components to facilitate proper orientation and alignment during assembly. These marks provide immediate visual feedback to the operator, eliminating the need for complex alignment mechanisms while maintaining simplicity of the overall device structure.
2Reliability
If lead retaining members are added to the base and cover, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The lead retention function is segmented into separate retaining members that are integrated into the base and cover components. This allows the retention mechanism to be independently designed and optimized without complicating the overall anchoring apparatus structure. The segmented approach enables modular assembly and simplifies manufacturing while ensuring reliable lead retention.
3Manufacturing precision
If a placement tool with retainer and channel system is used, then the manufacturing precision is improved, but the device complexity increases
Solution Approach 1:
The placement tool serves as an intermediary device between the anchoring apparatus and the cranium during installation. The retainer and channel system provides precise alignment and positioning guidance, ensuring accurate placement while simplifying the fastening process. This intermediary tool enables high manufacturing precision without requiring complex integrated systems in the final anchoring apparatus.

AI summary
Various embodiments of a placement tool for an apparatus to be fastened to a cranium with a fastener around a burr hole formed through the cranium are disclosed. The placement tool includes a receptacle adapted to hold the fastener, where the receptacle includes a channel extending between an upper opening of the receptacle and a lower opening of the receptacle along a channel axis. The placement tool further includes a retainer disposed within the channel of the receptacle, where the retainer includes a recess or a protrusion adapted to restrain the fastener against movement. The fastener opening of the apparatus is configured to align with the channel axis of the channel of the receptacle when the placement tool is engaged with the apparatus.
