Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current manual mechanical thrombectomy devices lack the capability to filter blood from undesired material and reinfuse filtered blood back into the patient.
Innovation Solution
A method involving a pump coupled to a filter system with multiple filter members and a visualization device, allowing for the aspiration, filtration, and reinfusion of blood, with the option to replace filter members to maintain efficiency and cleanliness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current manual mechanical thrombectomy devices are used to remove blood and undesired material, then the undesired material can be removed into a waste receptacle, but the blood cannot be filtered and reinfused back into the patient
Solution Approach 1:
The device is divided into distinct functional modules: an aspiration device for removing undesired material, a filter system with replaceable filter members for blood filtration, a visualization device for monitoring, and a reinfusion system for returning filtered blood to the patient. This segmentation allows each component to perform its specific function independently while maintaining overall system versatility.
Solution Approach 2:
The device integrates multiple functions into a single system: aspiration of undesired material, filtration of blood through replaceable filter members, visualization of the filtration process, and reinfusion of filtered blood. This multi-functionality enables the device to address both thrombectomy and blood recovery operations without requiring separate equipment.
2Reliability
If filter members are used to capture undesired material, then blood can be filtered, but the filter members require replacement to maintain efficiency and cleanliness
Solution Approach 1:
The filter members are designed as disposable or replaceable components that can be easily exchanged when saturated or contaminated. This approach ensures that filtration efficiency is maintained by removing compromised filter members, while the simplicity of replacement minimizes procedure time and avoids complex cleaning or regeneration processes.
Solution Approach 2:
The system enables discarding of saturated filter members and recovery of filtered blood through the reinfusion system. The filter members are discarded when they can no longer effectively capture undesired material, while the filtered blood is recovered and returned to the patient, maximizing resource utilization.
3Loss of information
If visualization device is used to monitor undesirable material, then the filtration process can be observed, but additional imaging and contrast use is required
Solution Approach 1:
The visualization device acts as an intermediary between the filtration process and the operator, providing direct visual monitoring of undesired material capture. This eliminates the need for separate imaging modalities and contrast agents by using the filter members themselves as the visualization medium, allowing operators to observe the filtration process in real-time.

Function Achieved in This Case
Enables effective filtration and reinfusion of blood, reducing the need for additional imaging and contrast use, thereby improving patient safety and procedure efficiency.
Implementation Method 1
aspirating fluid from the patient using the pump wherein the fluid contains an undesired material
Implementation Method 2
filtering the fluid using the first filter member to capture at least a portion of the undesired material
