Realtime Intraluminal Physics Modeling for Irrigation Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medical procedures involving irrigation face challenges in measuring and managing intraluminal pressures (ILP), flow rates, and temperature, which can lead to adverse patient outcomes such as pyelovenous backflow and tissue damage, due to the lack of understanding of how various physical parameters impact these factors during the procedure.
Innovation Solution
A medical system with a display and processor that allows real-time visualization and analysis of intraluminal states, including pressure, flow rate, and temperature, by receiving user inputs for medical parameters and applying differential equations to determine and graphically represent these states over time, enabling dynamic or static visualization.

Engineering Contradiction Analysis
1Illumination intensity
If irrigation is performed to improve visualization of target anatomy, then visual clarity is enhanced, but intraluminal pressure increases causing adverse outcomes such as pyelovenous backflow and sepsis
Solution Approach 1:
The system continuously monitors intraluminal pressure during irrigation procedures and provides real-time feedback to the operator through a user interface. When pressure approaches unsafe thresholds, the system alerts the operator to reduce irrigation flow rate or stop irrigation, preventing pyelovenous backflow and sepsis while maintaining adequate visualization
Solution Approach 2:
The system dynamically adjusts irrigation parameters (flow rate, pressure, temperature) based on real-time monitoring data and procedural conditions. By changing these parameters adaptively, the system maintains optimal visual clarity while keeping intraluminal pressure within safe limits to prevent adverse outcomes
2Productivity
If lasers are used internally for medical procedures, then tissue removal or modification is achieved, but temperatures increase causing damage to surrounding tissue
Solution Approach 1:
The system incorporates temperature sensors that continuously monitor tissue temperature during laser procedures. When temperature approaches thresholds that could cause damage to surrounding tissue, the system provides feedback to reduce laser power or pause treatment, enabling safe and efficient tissue removal
Solution Approach 2:
The system uses periodic monitoring and intermittent cooling cycles during laser procedures. By alternating between laser application and cooling periods, the system achieves effective tissue removal while preventing excessive temperature buildup that could damage surrounding healthy tissue
3Loss of information
If real-time monitoring of multiple physical parameters is implemented, then understanding of parameter impacts is improved, but device complexity increases
Solution Approach 1:
The system uses a single integrated platform that monitors multiple physical parameters (intraluminal pressure, temperature, flow rate) simultaneously through unified sensors and processing. This multi-functional approach provides comprehensive parameter understanding without requiring separate complex monitoring systems for each parameter
Solution Approach 2:
The system creates a virtual model of the procedural environment by digitally replicating physical parameter data in real-time. This digital twin allows comprehensive analysis of parameter interactions and their impacts without adding physical complexity to the actual surgical field
