Endoluminal Therapy Dwell Timing With 3D Position Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During endovascular therapy procedures, it is difficult for physicians to accurately follow the recommended speeds and activation times of endovascular therapy devices due to the challenges of navigating through tortuous vascular vessels, leading to under-treatment or over-treatment of vascular vessel portions, which is exacerbated by the reliance on two-dimensional imaging and the lack of real-time assessment.
Innovation Solution
The implementation of an endoluminal therapy monitoring system that synchronizes the activated dwell timing of therapy devices with their tracked positioning within the vascular vessel, using controllers and sensors to monitor and provide real-time feedback on treatment efficacy, ensuring optimal treatment duration at specific locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the physician manually navigates the endovascular therapy device through tortuous vascular vessels using two-dimensional imaging, then the procedure can be performed with existing equipment, but the treatment precision and dwell time control deteriorate leading to under-treatment or over-treatment
Solution Approach 1:
The system continuously monitors the position of the endovascular therapy device within the vascular vessel and provides real-time feedback to the physician. This feedback loop enables precise control of dwell time and treatment delivery by displaying the device location and treatment parameters, allowing the physician to adjust navigation and activation timing to achieve optimal treatment without under-treating or over-treating any segment.
Solution Approach 2:
The patent introduces three-dimensional spatial tracking and visualization capabilities to complement the existing two-dimensional imaging. By adding depth information and creating a multi-dimensional representation of device position within the vascular anatomy, the system enables precise localization and dwell time measurement that was not possible with planar imaging alone, thereby improving treatment precision without requiring completely new equipment infrastructure.
2Productivity
If the physician increases navigation speed to efficiently treat long vascular segments, then productivity improves, but treatment precision deteriorates causing under-treatment of specific locations
Solution Approach 1:
The system enables continuous treatment delivery by maintaining constant monitoring of device position and treatment parameters throughout the procedure. The real-time feedback ensures that treatment activation continues uniformly across all target segments without interruptions or gaps, allowing the physician to maintain efficient navigation speeds while ensuring every location receives the prescribed treatment dose.
Solution Approach 2:
Real-time position feedback allows the physician to maintain optimal navigation speed by immediately detecting and correcting any deviations. The system displays dwell time accumulation and treatment delivery status, enabling the physician to adjust speed dynamically to ensure uniform treatment across all segments while maintaining overall procedural efficiency.
3Loss of information
If the physician performs post-operative contrast runs to assess treatment adequacy, then treatment assessment completeness improves, but radiation exposure and procedure complexity increase
Solution Approach 1:
The system performs treatment assessment continuously during the procedure rather than requiring post-operative verification. By monitoring dwell time, position, and treatment delivery in real-time, the system provides immediate feedback on treatment adequacy, allowing the physician to make adjustments during the procedure and eliminating the need for additional contrast runs and radiation exposure.
Solution Approach 2:
The real-time feedback system displays accumulated dwell time and treatment delivery status for each vascular segment, providing immediate assessment of treatment completeness. This continuous monitoring replaces the need for post-procedure contrast imaging, as the physician can verify adequate treatment delivery during the procedure itself without additional radiation exposure.

AI summary
Various embodiments of the present disclosure encompass an endoluminal therapy system employing an endoluminal therapy device (21) and an endoluminal therapy monitoring controller (10). In support an endoluminal procedure, the endoluminal therapy device (21) is controlled to treat a site to be treated within a lumen. The controller (10) is operated to synchronize an activated dwell timing of the endoluminal therapy device (21) within the lumen to a tracked positioning of the endoluminal therapy device (21) contiguous with the site to be treated within the lumen. The controller (10) is further operated to monitor the site to be treated within the lumen induced by the endoluminal therapy device (21) during the synchronization by the controller (10) of the activated dwell timing of the endoluminal therapy device (21) within the lumen to the tracked positioning of the endoluminal therapy device (21) contiguous with the site to be treated within the lumen.
