Coronary Stenosis Visualization for PCI Treatment Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for diagnosing and educating patients about vascular blockages, such as stenosis, require multiple procedures and complex information communication, leading to inconvenience, misinterpretation, and reduced treatment outcomes due to the lack of efficient and user-friendly visual depictions.
Innovation Solution
A system and method using integrated medical and patient displays to provide diagnostic visualizations of vessel blockages, allowing simultaneous assessment and education by outputting images and treatment options to both medical personnel and patients, utilizing instruments for pressure measurements and imaging techniques like IVUS and OCT.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple separate procedures are used for diagnosis and treatment planning, then diagnostic accuracy is improved, but patient convenience and time efficiency deteriorate
Solution Approach 1:
The patent combines multiple diagnostic functions (pressure measurement, imaging via IVUS/OCT, and treatment planning) into a single integrated catheter system. This allows all diagnostic procedures to be performed during one catheterization session, eliminating the need for multiple separate visits while maintaining diagnostic accuracy through the use of multiple sensing modalities.
Solution Approach 2:
The catheter system is designed with multi-functionality, incorporating pressure sensors, imaging capabilities (IVUS and OCT), and treatment delivery mechanisms in a single device. This universal design enables the system to perform diagnosis, assessment, and treatment planning simultaneously during one procedure, resolving the contradiction between diagnostic thoroughness and time efficiency.
2Loss of information
If complex medical information is communicated orally or in writing, then information completeness is improved, but patient understanding and accessibility deteriorate
Solution Approach 1:
The system creates visual copies and representations of the patient's vascular anatomy and blockages through imaging technologies (IVUS, OCT) and pressure mapping. These visualizations are displayed on patient-friendly interfaces that translate complex medical data into easily understandable graphical formats, allowing patients to see their own condition and treatment options without requiring complex verbal or written explanations.
Solution Approach 2:
The patent introduces an intermediary visual display system that acts as a mediator between the complex diagnostic data and the patient. The display system translates technical medical information into intuitive visual representations, making the information both complete and accessible simultaneously by serving as an intermediary translation layer.
3Reliability
If multiple treatment sessions are scheduled, then thorough assessment is improved, but treatment efficiency and patient convenience deteriorate
Solution Approach 1:
The system merges assessment functions that traditionally required multiple sessions into a single catheterization procedure. By integrating pressure measurement, imaging (IVUS/OCT), and treatment planning capabilities in one device, the system achieves thorough assessment while improving treatment efficiency by eliminating the need for multiple scheduled sessions.
Solution Approach 2:
The patent enables continuous assessment and treatment planning during a single uninterrupted catheterization procedure. The useful action of diagnosing and planning treatment continues without interruption or separation into multiple sessions, thereby improving both assessment thoroughness and treatment efficiency through continuous workflow.
