Solution Overview
Problem
Existing rescue tools are bulky, heavy, and inefficient, lacking the compactness and power efficiency required for self-contained and portable operations, with inadequate control systems to manage power consumption and hydraulic fluid management.
Innovation Solution
A portable rescue tool with an integrated pump and motor, controlled by a controller that adjusts power and hydraulic fluid flow based on sensors and user input, optimizing force and speed through a common shaft configuration and adaptive valve control to ensure compactness and efficient operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a catheter is advanced through the aorta to reach the iliac or femoral arteries, then the pump can be positioned distally for treatment, but the procedure becomes more complex and time-consuming with increased risk of complications
Solution Approach 1:
The catheter system is divided into distinct segments: a introducer catheter for initial access and pump delivery, and a separate treatment catheter for thrombus removal. This segmentation allows the pump to be delivered via a relatively simple femoral approach while the treatment catheter can be advanced through the aorta to reach distal lesions, separating the complex aortic navigation from the pump implantation procedure.
Solution Approach 2:
The pump is delivered and positioned in the distal iliac or femoral artery through the femoral approach before the treatment catheter is advanced through the aorta. This preliminary positioning of the pump allows it to be ready for immediate use once the treatment catheter reaches the thrombus, avoiding the need to navigate the treatment catheter through the entire aortic path first.
2Ease of operation
If the pump is delivered via a femoral approach, then the initial access is simpler and safer, but the pump may not reach distal lesions in the iliac or femoral arteries
Solution Approach 1:
The system uses two separate catheters with distinct functions: the introducer catheter provides simple femoral access for pump delivery, while the treatment catheter is specifically designed to navigate the aorta and reach distal iliac or femoral lesions. This segmentation allows each catheter to be optimized for its specific task.
Solution Approach 2:
The introducer catheter acts as an intermediary that delivers the pump to a distal position through the femoral approach, while the treatment catheter serves as another intermediary that navigates the aorta to reach the same distal location. These intermediary catheters enable the pump to be positioned where it can treat lesions that would otherwise be inaccessible via simple femoral approach.
3Adaptability or versatility
If a transapical approach is used to deliver the pump, then the pump can reach distal lesions, but the procedure requires open chest surgery and has higher morbidity
Solution Approach 1:
The procedure is segmented into two independent catheter-based interventions: femoral access for pump delivery and transaortic access for treatment catheter delivery. This segmentation eliminates the need for open chest surgery required by the transapical approach, as the pump can be delivered through the percutaneous femoral route while the treatment catheter navigates the aorta to reach distal lesions.
Solution Approach 2:
The system combines the advantages of multiple approaches into a single hybrid procedure: the femoral introducer catheter provides the simplicity of percutaneous access, while the treatment catheter provides the reach of transaortic access. This multi-functional approach allows the system to achieve distal lesion treatment without requiring open surgery.
