PCI Planning Interface Synchronizing Stent Position with Pressure Ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for planning percutaneous coronary interventions (PCI) face challenges in integrating angiography and physiologic data, making it difficult to determine the optimal stent positioning, length, and diameter effectively.
Innovation Solution
A graphical user interface is provided that allows clinicians to visualize a stent within a blood vessel or a graph of pressure ratio, enabling them to simulate therapeutic procedures by modifying stent properties such as position and length. This interface automatically synchronizes changes in the stent's representation within the vessel and the pressure ratio graph.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If clinicians use conventional separate angiography and pressure measurement methods, then data collection is straightforward, but integration and analysis of the data becomes difficult
Solution Approach 1:
The patent combines angiography data and pressure measurement data into a single integrated system. The angiography system and pressure measurement system are merged to co-process and display both types of data simultaneously, allowing clinicians to analyze the relationship between anatomical structure and physiological function without switching between separate systems.
Solution Approach 2:
The system is designed to perform multiple functions: it conducts angiography, measures pressure, processes both types of data, and displays integrated results. This multi-functional approach eliminates the need for separate dedicated systems for each function, reducing overall complexity while improving data integration.
2Productivity
If clinicians manually analyze separate angiography and pressure data, then analysis flexibility is maintained, but time required for planning increases
Solution Approach 1:
The system performs preliminary processing and integration of angiography and pressure data automatically before the clinician needs to make treatment decisions. The data is pre-aligned, pre-processed, and ready for immediate analysis, eliminating the need for manual time-consuming integration during the critical decision-making period.
Solution Approach 2:
The system provides real-time feedback by displaying integrated angiography and pressure data simultaneously, allowing clinicians to immediately see the relationship between anatomical findings and physiological measurements. This immediate feedback loop accelerates the planning process compared to manual sequential analysis.
3Reliability
If clinicians use traditional PCI planning methods, then procedural simplicity is maintained, but prediction of treatment efficacy is limited
Solution Approach 1:
The system introduces an intermediary processing layer that automatically correlates angiography data with pressure measurement data. This intermediary function bridges the gap between anatomical imaging and physiological measurements, enabling more accurate prediction of treatment efficacy without requiring the clinician to manually perform complex data correlation.
4Manufacturing precision
If the system provides detailed interactive visualization of stent positioning, then planning precision is improved, but user interface complexity increases
Solution Approach 1:
The interface is segmented into distinct functional panels: one for angiography visualization, one for pressure data display, one for stent positioning, and one for integrated analysis. Each panel handles a specific aspect of the planning process independently, making the overall complex system more manageable and easier to operate through modular interaction.

AI summary
Devices, systems, and methods directed to evaluating a vessel of a patient are provided. The method includes outputting, to a display, a screen display including: a visual representation of a pressure ratio of pressure measurements obtained by first and second instruments positioned within a vessel while the second instrument is moved longitudinally through the vessel and the first instrument remains stationary within the vessel; and a visual representation of the vessel; receiving a user input to modify one of the visual representations of the pressure ratio and the vessel to simulate a therapeutic procedure; and updating the screen display, in response to the user input, including: modifying the selected one of the visual representation of the pressure ratio and the vessel based on the received user input; and correspondingly modifying the unselected one of the visual representation of the pressure ratio and the vessel.
