Prosthetic Valve Actuator Attachment Status Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current prosthetic valve technologies lack a mechanism to ensure proper detachment and attachment status of the actuation mechanism, which is crucial for successful implantation and operation, leading to potential complications during surgical procedures.
Innovation Solution
A prosthetic valve actuator attachment status detection system is introduced, featuring a pressure sensor integrated with the actuator and a detection module that determines the attachment status by comparing sensor output to predetermined pressure values, indicating whether the actuator is properly attached or detached from the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pressure sensor is integrated with the actuator to detect attachment status, then the reliability of prosthetic valve deployment is improved, but the device complexity increases
Solution Approach 1:
The pressure sensor is integrated within the actuator assembly, with the sensor positioned to detect pressure changes between the actuator and the valve frame. This nesting approach allows the sensor to be incorporated into the existing actuator structure without requiring separate external sensing components, thereby improving reliability while managing complexity through efficient spatial arrangement.
Solution Approach 2:
The pressure sensor acts as an intermediary element that indirectly detects attachment status by measuring pressure changes between the actuator and frame, rather than directly sensing mechanical connection. This intermediary approach converts mechanical attachment information into measurable pressure signals, improving detection reliability while keeping the sensing mechanism relatively simple.
2Ease of operation
If the actuation mechanism is made detachable for retrieval, then the ease of operation is improved, but the risk of improper detachment increases
Solution Approach 1:
The pressure sensor provides real-time feedback on the attachment status between the actuator and valve frame during the entire procedure. This feedback mechanism allows operators to confirm proper attachment before deployment and verify successful detachment after expansion, ensuring reliability while maintaining the ease of retrieval operation. The system continuously monitors pressure changes that indicate attachment or detachment events.
Solution Approach 2:
The system performs preliminary detection of attachment status before critical operations such as valve expansion or actuator withdrawal. By checking attachment status in advance through pressure sensing, the system prevents improper detachment or expansion, ensuring that the detachable mechanism is used correctly while maintaining operational ease when properly configured.
