Excisional Device with Integrated Imaging for Vascular Occlusions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical devices for vascular interventions lack the capability for minimally invasive, reliable, and widely applicable excisional and interventional procedures, especially for acute and chronic total vessel occlusions.
Innovation Solution
Development of hand-held or mounted, manually or robotically guided medical devices that integrate excisional and interventional capabilities with integrated imaging, allowing for single or multiple insertion and excision procedures in vascular and other tubular areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current medical devices are used for vascular interventions, then basic vascular access is possible, but excisional and interventional capabilities for total vessel occlusions are insufficient
Solution Approach 1:
The device integrates multiple functions including excisional capabilities, interventional capabilities, and imaging capabilities into a single platform. The system can perform atherectomy, thrombectomy, and other vascular interventions, making it universally applicable to various vascular pathologies including total occlusions that previous single-function devices could not reliably treat.
2Adaptability or versatility
If multiple separate devices are used for different vascular procedures, then specific functions can be performed, but procedural complexity and time increase
Solution Approach 1:
The patent combines excisional devices, interventional devices, and imaging systems into a single integrated platform. This merging eliminates the need to exchange between multiple separate devices during procedures, reducing procedural time and complexity while maintaining all necessary functional capabilities for comprehensive vascular treatment.
Solution Approach 2:
The device employs nested structures where smaller functional components are housed within larger device architectures. The excisional and interventional elements can be nested within the imaging system housing, allowing compact integration of multiple functions that can be deployed sequentially or simultaneously without requiring multiple separate access points.
3Measurement precision
If imaging is performed outside the procedural site, then equipment complexity is reduced, but imaging clarity is distorted or impeded
Solution Approach 1:
The imaging system is merged with the procedural device, positioning imaging capabilities directly at the treatment site within the vasculature. This integration ensures high-resolution imaging clarity by eliminating external interference while the modular architecture of the integrated system manages complexity through coordinated subsystems rather than separate external equipment.

AI summary
A platform device for material excision or removal from vascular structures for either handheld or stereotactic table or robotics platform use may comprise a work element or elements configured to selectively open and close at least one articulable beak or scoopula configured to penetrate and remove intra-vascular materials or obstructions or follow a central lumen of another device or over a wire in a longitudinal direction. Flush and vacuum tissue transport mechanisms may be incorporated as well as single or multiple arrays of image guidance elements, directional elements, ablation elements and other interventional assistance elements. A single tube 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 or scoopulas and provisions for simultaneous or differential beak or scoopula closing under their differential rotation may be incorporated.
