Adjunctive Effector Deployment for Intravascular Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intravascular systems face challenges in performing localized procedures due to obstructed access and misdirection of instruments in concentric cylinder systems, making it difficult to effectively target and treat thrombi, emboli, or foreign bodies within vascular regions.
Innovation Solution
An adjunctive effector deployment system is introduced, which includes a mounting element that slidably couples to the inner shaft of a concentric cylinder system, allowing for controlled advancement and retraction of an effector component to perform procedures within a localized target zone, enhancing the capability to remove thrombi, emboli, or administer drugs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If concentric cylinder systems are used to demark localized regions of tissue, then the capability to perform procedures on specific target areas is improved, but access for introducing instruments to the localized region becomes difficult
Solution Approach 1:
The system is divided into separate functional components: the concentric cylinder system for localization and the effector deployment system for instrument delivery. This segmentation allows each component to optimize its function independently, with the effector system providing unobstructed access to the target zone defined by the cylinders.
Solution Approach 2:
The effector deployment system is nested within or alongside the concentric cylinder system, with the effector component traveling through the shaft of the concentric cylinder system to reach the target zone. This nested arrangement allows both systems to coexist without interfering with each other's primary functions.
2Adaptability or versatility
If connections are added at the proximal portion of concentric cylinder systems, then additional functionality is provided, but access along the shaft for feeding instruments becomes obstructed
Solution Approach 1:
The effector deployment system acts as an intermediary that bridges the proximal control region and the distal target zone. It provides a dedicated pathway through the shaft that is separate from the connections at the proximal portion, allowing instruments to reach the target zone without being blocked by proximal connections.
3Ease of operation
If guidewire pathways are established in concentric cylinder systems, then instrument delivery is enabled, but control of the guidewire pathway to remain parallel to the shaft becomes difficult
Solution Approach 1:
The effector component is designed to self-align and follow the shaft of the concentric cylinder system to the target zone. The shaft itself serves as a guide, and the effector system utilizes this existing structure to maintain proper alignment without requiring complex external control mechanisms.
4Manufacturing precision
If the distal portion of concentric cylinder systems is positioned at the target region, then localized treatment is achieved, but the proximal portion becomes complex for mounting additional features
Solution Approach 1:
The effector deployment system is designed as a universal platform that can accommodate multiple different effector components for various procedures (thrombus removal, emboli extraction, foreign body removal, drug administration). This multi-functional design eliminates the need for complex proximal structures by using a single adaptable system.
