Remote Catheter Control System for Vascular Procedures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current catheter-based medical procedures for treating vascular diseases, such as angioplasty and stent placement, require manual operation and lack remote control capabilities, which can be invasive and inefficient, especially for procedures involving expandable percutaneous devices like angioplasty balloons and stents.
Innovation Solution
A catheter procedure system that includes a bedside system with a robotic catheter system and an inflation device, along with a remote workstation that allows for remote control of the catheter and inflation device through a user interface, enabling precise control and monitoring of procedures from a distant location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual operation of catheter-based procedures is used, then direct control and simplicity of system are maintained, but invasiveness increases and procedural precision decreases
Solution Approach 1:
The system divides the catheter control functions into separate modular components: robotic catheter system, inflation device, contrast media delivery device, and remote workstation. Each module operates independently but coordinates through standardized interfaces, enabling precise control without requiring a monolithic complex system
Solution Approach 2:
A remote workstation acts as an intermediary between the operator and the catheter system. The workstation receives user inputs and transmits control signals to the robotic catheter system and inflation device, allowing precise procedural control from a distance while simplifying the direct control interface
2Reliability
If remote control capabilities are added to catheter systems, then procedural precision and safety improve, but device complexity increases
Solution Approach 1:
The remote workstation serves multiple functions: controlling catheter navigation, managing inflation device operation, coordinating contrast media delivery, and monitoring procedural parameters. This multi-functional approach improves reliability without proportionally increasing complexity by consolidating control functions in a single unified interface
Solution Approach 2:
The system incorporates real-time feedback loops where the remote workstation continuously monitors catheter position, inflation pressure, and procedural parameters, then adjusts control signals accordingly. This feedback mechanism enhances procedural safety by enabling dynamic adaptation to changing conditions while maintaining manageable system complexity through automated control algorithms
