Graphical Guidance For Flexible Device Buckling During Image-Guided Procedures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing minimally invasive medical procedures face challenges in intuitively controlling flexible and steerable elongate devices, such as steerable catheters, due to the complexity of managing multiple degrees of freedom during image-guided procedures, with a need for improved guidance and control systems.
Innovation Solution
A method and system for displaying guidance information using a graphical user interface that integrates data from a tracking system to calculate conditions along the flexible body of an elongate device, determine supplemental guidance, and augment images with this information for display, enhancing control and management of these devices.

Engineering Contradiction Analysis
1Ease of operation
If traditional control methods are used for flexible and steerable elongate devices, then the device can be inserted and navigated through anatomic passageways, but the complexity of managing multiple degrees of freedom makes control non-intuitive and difficult
Solution Approach 1:
The system employs real-time feedback by continuously monitoring the shape and position of the elongate device using shape sensors and tracking systems. This feedback is displayed through a graphical user interface that shows the device configuration, allowing operators to intuitively understand and control the device's multiple degrees of freedom during minimally invasive procedures.
2Ease of operation
If detailed shape data is collected and processed in real-time, then intuitive control and navigation are improved, but computational requirements and system complexity increase
Solution Approach 1:
The system creates a virtual copy or digital representation of the elongate device's physical shape and position in real-time. Shape sensors measure the actual device configuration, and this data is used to generate a corresponding virtual model displayed on the graphical user interface, enabling intuitive control without requiring complex direct manipulation of all device parameters.
