Automated Guide Wire Navigation System for Coronary Procedures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current catheter-based procedures for navigating guide wires in cardiovascular interventions face challenges due to poor visualization and lack of depth perception, making it difficult to precisely direct the distal tip of the guide wire to the desired location within the coronary anatomy.
Innovation Solution
A catheter procedure system equipped with a guide wire advance/retract actuator and a rotate actuator, controlled by a workstation with a user interface and controller, which uses image feedback to automatically adjust the guide wire's path, rotating and retracting it until it reaches the desired position.

1Productivity
If manual insertion of guide wire is used, then the procedure can be performed with simple equipment, but the time required to navigate past junction points is excessive and precision is poor
Solution Approach 1:
The patent replaces manual mechanical manipulation of the guide wire with an automated robotic system that uses image guidance and computer control to navigate the guide wire through coronary anatomy. The robotic catheter system substitutes human hand-eye coordination with automated image processing and robotic actuation, thereby reducing procedure time while managing system complexity through integration.
Solution Approach 2:
The system incorporates automated image processing and path planning algorithms that enable the catheter system to self-navigate the guide wire through the coronary vasculature. The robotic system autonomously adjusts guide wire position and orientation based on real-time image feedback, reducing reliance on operator skill and experience while improving navigation efficiency.
2Measurement precision
If fluoroscopy is used for visualization, then the procedure can be performed with standard equipment, but depth perception is lacking and precise direction of guide wire tip is difficult
Solution Approach 1:
The patent introduces an intermediate image processing and visualization system that translates fluoroscopic images into three-dimensional spatial information. The system uses image processing algorithms to reconstruct coronary anatomy and guide wire position, providing the operator with enhanced depth perception and spatial awareness without requiring complex additional imaging hardware.
Solution Approach 2:
The system transforms two-dimensional fluoroscopic images into three-dimensional spatial representations of coronary anatomy and guide wire position. By adding the dimension of depth perception through image processing and visualization, the system enables precise guide wire tip positioning while maintaining compatibility with standard fluoroscopy equipment.

AI summary
A catheter procedure system includes a bedside system having a guide wire, a guide wire advance/retract actuator coupled to the guide wire and a guide wire rotate actuator coupled to the guide wire and a workstation coupled to the bedside system. The workstation includes a user interface, at least one display and a controller coupled to the bedside system, the user interface and the at least one display. The controller is programmed to advance the guide wire through a path using the guide wire advance/retract actuator, determine if the guide wire is in a desired path based at least on at least one image of a region of interest, rotate the guide wire using the guide wire rotate actuator if the guide wire is not in the desired path, wherein the guide wire is rotated a predetermined amount, and retract the guide wire using the guide wire advance/retract actuator. The steps of advancing the guide wire and retracting and rotating the guide wire using guide wire advance/retract actuator and the guide wire rotate actuator are repeated until the guide wire is in the desired path. The guide wire is advanced to a desired position using the guide wire advance/retract actuator.
