Virtual Intravascular Training System for Guided Therapeutic Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current training methods for novice users in intravascular procedures are limited, as they rely on shadowing experienced clinicians and participating in proctored cases, which are scarce, and existing simulators lack the ability to guide users in data collection and therapeutic planning effectively.
Innovation Solution
A virtual, interactive teaching environment that uses computing systems to guide users through the collection of intravascular data and therapeutic planning, providing feedback on their choices and decisions, allowing them to practice and learn in a simulated setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If novice users learn by shadowing experienced clinicians and participating in proctored cases, then they gain practical experience, but the availability and frequency of training opportunities are limited
Solution Approach 1:
The patent creates a virtual copy of the intravascular procedure environment using computer-generated 3D models of blood vessels, lesions, and medical devices. This allows novice users to practice procedures in a simulated setting that replicates real clinical scenarios without requiring actual patients or experienced clinicians to be present, thereby solving the contradiction between training quality and training availability
Solution Approach 2:
The system prepares training scenarios in advance by generating virtual blood vessel models with pre-defined lesions and providing users with planning tools before they execute procedures. This preliminary preparation allows users to practice decision-making and procedural planning without needing real-time guidance from experienced clinicians, increasing training availability while maintaining quality
2Ease of operation
If physical simulators are used to simulate vessels, then users can physically handle intravascular devices, but the systems have limited mobility and require attachment to physical devices
Solution Approach 1:
The patent replaces the mechanical physical simulator system with a computer-based virtual reality system. Instead of using physical models that require mechanical attachment to imaging devices, the system uses software-generated 3D visualizations that can be accessed on standard computing devices, eliminating the mobility constraints while preserving the ability to interact with virtual representations of intravascular devices
3Ease of operation
If existing simulators allow physical handling of devices, then users gain hands-on experience, but they cannot apply collected data to formulate therapeutic plans or identify lesion locations
Solution Approach 1:
The patent merges the device handling simulation with data visualization and therapeutic planning capabilities into a single integrated system. Users interact with virtual intravascular devices while simultaneously viewing simulated imaging data, lesion characteristics, and therapeutic options. This combination allows users to practice the complete workflow from device manipulation through data interpretation to treatment planning, eliminating the gap between hands-on experience and data application
