Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current thrombectomy devices are inadequate for safely and effectively removing both hard and soft clots in deep vein thrombosis (DVT) and acute pulmonary embolism (PE) without causing vascular trauma or significant blood loss, and they often require multiple procedures and have high costs.
Innovation Solution
A thrombectomy system that combines Artificial Intelligence with a self-expandable wire mesh web and radial ring-shaped structure within a catheter, allowing for the capture and removal of clots in a single pass while minimizing trauma and blood loss, and includes a method for real-time monitoring and adjustment of procedures during surgery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional thrombectomy devices are used to remove clots, then clot removal function is provided, but vascular trauma and blood loss occur
Solution Approach 1:
The patent employs a flexible wire mesh web structure that can conform to the vessel geometry and gently capture clots without causing vascular trauma. The thin, flexible nature of the mesh allows it to navigate through vessels smoothly while maintaining structural integrity for effective clot capture and removal.
Solution Approach 2:
The thrombectomy device integrates multiple functions into a single system: navigation to clot location, aspiration of thrombus material, and capture of fragmented particles. This multi-functional approach eliminates the need for separate devices for each step, reducing overall vascular manipulation and associated trauma.
2Reliability
If multiple thrombectomy procedures are performed to remove hard and soft clots, then complete clot removal is achieved, but procedure time and cost increase
Solution Approach 1:
The device is designed to handle both hard and soft clots simultaneously through its wire mesh structure and aspiration system. The mesh captures various clot types while the aspiration mechanism removes them in a single integrated action, eliminating the need for multiple sequential procedures.
Solution Approach 2:
The continuous aspiration flow maintains constant removal of thrombus material throughout the procedure, preventing re-accumulation and ensuring complete clearance in one continuous action rather than requiring multiple discrete intervention steps.
3Productivity
If mechanical thrombectomy devices are used, then clot removal speed is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The device is divided into distinct functional segments: the wire mesh web for clot capture, the aspiration catheter for removal, and the delivery system for navigation. This segmentation allows each component to be optimized independently while maintaining overall simplicity and reducing manufacturing complexity.
Solution Approach 2:
The wire mesh web is nested within the catheter structure, and the entire assembly is delivered through a compact delivery system. This nested configuration minimizes the profile during delivery while providing full functionality during deployment, reducing apparent device complexity without compromising performance.

AI summary
A method of alerting a user to the existence of an anomalous variation in local conditions during use of a thrombus retrieval device in a patient. The method including: inserting a thrombus retrieval device into a blood vessel in a patient having a thrombus within the vessel while a region including the thrombus is under sensed observation. Sensing a signal responsive to at least thrombus variations, the variations being in response to the use of the thrombus retrieval device, sensing the existence of the anomalous variation in the local conditions, with a server receiving data of the sensed anomalous variation in local conditions. The server executes software to identify available procedures to be used after identification of one or more anomalous variations in local conditions related to the sensed anomalous variation in local conditions. The server provides first visual data visible to a human eye identifying the available procedures.
