Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If imaging system and robotic catheter system are operated separately, then each system can be controlled independently, but the overall procedure efficiency and coordination between imaging and device positioning deteriorates
Solution Approach 1:
The patent combines the imaging system control and robotic catheter system control into a single integrated system. The control system receives user inputs and generates coordinated control signals for both the imaging system (to capture images) and the robotic catheter system (to position devices), enabling synchronized operation and improving overall procedure efficiency while maintaining manageable complexity through unified control architecture.
2Measurement precision
If manual control of imaging and catheter positioning is used, then operator flexibility is maintained, but precision and coordination between imaging captures and device movements deteriorates
Solution Approach 1:
The control system incorporates feedback mechanisms where sensor data from the robotic catheter system and imaging system are continuously monitored. The control system processes this feedback information and automatically adjusts control signals to maintain precise coordination between device positioning and imaging captures, improving positioning accuracy while reducing the operational burden on the operator.
Solution Approach 2:
The integrated control system performs automatic coordination functions without requiring manual intervention for each imaging capture and device movement. The system autonomously generates control signals based on user inputs and sensor feedback, enabling self-coordinated operation that enhances precision while simplifying the operator's task to high-level command input.
3Loss of time
If separate control systems are used for imaging and catheter positioning, then system modularity is maintained, but the coordination and synchronization between image capture and device movement deteriorates
Solution Approach 1:
The control system is pre-configured with the operational parameters and communication protocols for both the imaging system and robotic catheter system. When a user initiates a procedure, the control system has already established the coordination framework and can immediately generate synchronized control signals, eliminating setup time and achieving rapid synchronization between image capture and device movement.

AI summary
A robotic catheter procedure system includes a bedside system and a workstation. The bedside system includes an actuating mechanism configured to engage and to impart movement to a percutaneous device. The workstation includes a user interface and a control system configured to be operatively coupled to the user interface, the bedside system, and a medical imaging system. The control system is responsive to a first input and to a second input, and the user interface receives the second input from a user. The control system is configured to generate a first control signal to the medical imaging system based on the first input, and the medical imaging system captures at least one image in response to the first control signal. The control system is configured to generate a second control signal to the actuating mechanism based on the second input, and the actuating mechanism causes movement of the percutaneous device in response to the second control signal. The first input is indicative of upcoming percutaneous device movement.
