Robotic Catheter Navigation Error Correction via Threshold Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current robotic catheter systems lack the capability to guide users in executing corrective actions to address critical situations such as catheter collisions or system malfunctions, which can lead to further complications.
Innovation Solution
A method for operating a robotic catheter system that includes inserting a steerable catheter into a bodily lumen, recording navigation parameters, and displaying a graphical representation of these parameters relative to threshold values. This graphical representation highlights potential navigation errors and provides corrective actions to prevent or correct these errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If robotic catheter systems provide warnings for critical situations, then safety awareness is improved, but the system cannot guide users in executing corrective actions
Solution Approach 1:
The system continuously monitors navigation parameters and provides real-time feedback through graphical representations. When parameters approach threshold values indicating critical situations, the system not only warns the operator but also guides corrective actions by showing how to adjust navigation to return to safe operating conditions.
Solution Approach 2:
The graphical user interface acts as an intermediary between the complex sensor data and the operator. It translates raw navigation parameters into intuitive visual displays that clearly indicate both the critical situation and the corrective actions needed, bridging the gap between system monitoring and operator response.
2Difficulty of detecting and measuring
If the system monitors navigation parameters in real-time, then detection capability is improved, but the system lacks the ability to provide corrective guidance
Solution Approach 1:
The system segments the monitoring and guidance functions into distinct visual elements. Different navigation parameters are displayed separately with their own threshold indicators, and corrective guidance is provided as discrete actionable recommendations rather than a single complex message.
Solution Approach 2:
The system adds a temporal dimension to the monitoring display by showing historical parameter values alongside current readings. This allows operators to see trends and understand how parameter changes lead to critical situations, providing context for corrective actions.

AI summary
A robotic catheter system and methods for implementing corrective actions during use thereof. A method comprises: providing a catheter that has one or more bendable segments and a catheter tip, inserting the catheter into a bodily lumen and navigating the catheter through the lumen along an insertion trajectory while an actuation unit applies an actuation force to the one or more bendable segments; recording a navigation parameter in relation to the insertion trajectory while the catheter is moved through the lumen, displaying, on a display, a graphical representation of the navigation parameter relative to a threshold value indicative of a location along the insertion trajectory where a navigation error of the catheter can occur or has occurred; and outputting to the display an interactive user-guide showing one or more than one corrective actions that can be taken to correct and/or prevent the navigation error.
