Articulable Beak In-Situ Delivery Device for Single-Insertion Multi-Site Material Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medical devices for in-situ material delivery face challenges such as multiple insertions causing trauma, foreign material transfer, and inefficient delivery of multiple materials to target sites, especially in deep tissues, due to their open-ended design and need for repeated penetration.
Innovation Solution
A hand-held or mounted device with a monolithic work element featuring articulable beaks that can be closed between deliveries, allowing for single insertion and multiple deliveries through a coaxially-disposed inner or outer tube configuration, minimizing tissue trauma and ensuring precise delivery of materials to the target site.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple insertions are used to deliver materials to different sites, then complete delivery to multiple sites is achieved, but tissue trauma and foreign material transfer increase
Solution Approach 1:
The device segments the delivery function into multiple discrete material chambers that can be independently activated. Each chamber contains a different material and can be delivered to a separate target site through the single insertion pathway, enabling multi-site delivery without repeated penetrations.
Solution Approach 2:
The single insertion device serves multiple functions by incorporating various material chambers (e.g., hemostatic agent, antibiotic, antifungal, antiviral, analgesic) that can be delivered to different sites. The device structure allows selective activation of different chambers to address multiple medical needs through one penetration event.
2Ease of operation
If open-ended design is used for material delivery, then ease of material loading is achieved, but foreign material transfer and contamination occur
Solution Approach 1:
The material chambers are nested within the device body in a sealed configuration. Each chamber is contained within the device structure until activation, preventing foreign material transfer and contamination. The nested design allows materials to be loaded and sealed within the device before insertion, maintaining sterility throughout the procedure.
3Object-affected harmful factors
If single insertion is used to minimize trauma, then tissue trauma is reduced, but delivery of multiple materials to deep tissues becomes inefficient
Solution Approach 1:
The device incorporates dynamic activation mechanisms that allow selective opening of different material chambers at different depths and locations. The articulable beaks can be positioned and activated dynamically during the procedure, enabling efficient delivery of multiple materials to deep tissues through a single insertion without requiring repeated penetrations.

AI summary
An in-situ material delivery device for handheld, stereotactic table or MRI stage use may comprise a work element configured to selectively open and close at least one articulable beak configured to penetrate tissue to a target delivery site, or follow a central lumen of another device or other guiding modality, and then to deliver selected materials. Such a device may deliver a variety of materials such as markers, radio-active pellets, medications, other devices, and other materials of solid, liquid or gaseous form to a target site, and materials of similar nature may also be captured and removed from a target site. A single tube with or without coatings or an inner sheath and an outer sheath which may be co-axially disposed relative to a work element may be configured to actuate a beak or beaks and internal delivery mechanisms simultaneously. One embodiment of this device may be applicable to field use or one time use.
