Adaptive Guidance Profiles for Robotic Catheter Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing robotic catheter-based systems face challenges in navigating complex vasculature due to the need for additional support at the distal end of catheters or guidewires, particularly in tortuous or calcified vasculature, requiring multiple operators for exchanging over-the-wire catheters, and rapid exchange catheters are inadequate for distal support.
Innovation Solution
A data capture system that generates profiles using captured parameters from a reference operator's inputs, including motion and load parameters, to provide adaptive guidance for elongated medical devices, enabling single-operator control and improved navigation in complex anatomies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If over-the-wire catheters are used to provide distal support in complex vasculature, then navigation capability is improved, but device complexity and operational complexity increase requiring multiple operators
Solution Approach 1:
The robotic system nests multiple functional components within a single integrated platform - the robotic catheter contains drive mechanisms, sensors, and actuation systems nested within the catheter structure itself, eliminating the need for separate support devices and reducing overall system complexity
Solution Approach 2:
The robotic system provides self-service through automated control capabilities where the robotic catheter can be independently manipulated by a single operator using automated navigation and actuation systems, eliminating the need for multiple operators to manage separate devices
2Reliability
If multiple operators are used for exchanging catheters, then operational control is improved, but productivity decreases and procedure time increases
Solution Approach 1:
The robotic system enables self-service operation where a single operator can independently control all catheter manipulation functions through an integrated control interface, eliminating the need for multiple operators and thereby increasing procedural efficiency and productivity
Solution Approach 2:
The robotic control system performs multiple functions - navigation, manipulation, data capture, and guidance - all through a single integrated control interface, allowing one operator to replace multiple specialized operators and improve workflow efficiency
3Ease of operation
If rapid exchange catheters are used for easier manipulation, then ease of operation is improved, but navigation capability in complex vasculature deteriorates due to inadequate distal support
Solution Approach 1:
The robotic system dynamically adjusts operational parameters including force application, manipulation speed, and actuation intensity to provide both ease of operation at the control interface and adequate distal support for navigation, optimizing both ease of operation and navigation capability simultaneously
Solution Approach 2:
The robotic system incorporates feedback mechanisms that provide real-time information about catheter position and manipulation forces, allowing the operator to maintain ease of operation while the system automatically compensates to ensure adequate distal support and navigation capability

AI summary
An example data capture system generates profile using captured parameters from a reference operator. The data capture system includes a user interface to receive inputs from a reference operator for operation of one or more elongated medical devices (EMDs); a sensor system to capture parameters associated with the inputs from the reference operator; and a processing unit to generate at least one profile using the captured parameters, the profile being associated with a characteristic of the reference operator.
