Endoluminal Therapy Dwell Timing With 3D Position Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During endovascular therapy procedures, it is difficult for physicians to accurately follow 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 sections, 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, providing real-time feedback and assessment to ensure optimal treatment.
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 deteriorates leading to under-treatment or over-treatment of vascular sections
Solution Approach 1:
The patent transitions from two-dimensional imaging to three-dimensional mapping by creating a virtual model of the vascular vessel using multiple angiographic images. This 3D representation provides depth information and spatial relationships that 2D imaging cannot provide, enabling precise tracking of the therapy device position and orientation within the complex tortuous vessel geometry.
Solution Approach 2:
The system continuously tracks the position of the therapy device relative to the pre-created 3D vascular map and provides real-time feedback to the physician. This feedback mechanism allows the physician to see exactly where the device is located within the vessel and adjust navigation to achieve the recommended dwell time at each treatment segment, preventing both under-treatment and over-treatment.
2Reliability
If the physician relies on mental mapping of therapy device positions without real-time assessment, then the procedure can proceed without additional monitoring equipment, but the reliability of treatment assessment deteriorates requiring post-operative contrast runs
Solution Approach 1:
The system provides continuous real-time feedback on the therapy device position and the cumulative dwell time at each location along the vascular vessel. The physician can monitor the treatment progress throughout the procedure and make immediate adjustments, eliminating the need for post-operative contrast runs to assess treatment adequacy.
Solution Approach 2:
The patent introduces a computing device as an intermediary between the therapy delivery system and the physician. This intermediary processes imaging data, creates the 3D vascular map, tracks device position, calculates dwell times, and presents integrated information to the physician, enabling real-time treatment assessment without requiring additional monitoring equipment or post-procedure verification.
3Productivity
If the endovascular therapy device is advanced quickly through tortuous vascular bends, then the procedure efficiency increases, but the treatment quality deteriorates causing under-treatment of vessel sections
Solution Approach 1:
The system dynamically adjusts the recommended dwell time based on the actual navigation speed and position of the therapy device. As the physician navigates through tortuous sections, the system calculates the cumulative time the device has spent at each location and provides real-time guidance to achieve the target dwell time, allowing efficient navigation while maintaining treatment quality.
Solution Approach 2:
The real-time feedback mechanism allows the physician to navigate efficiently through the vessel while receiving continuous information about the cumulative dwell time at each segment. This enables the physician to maintain optimal speed through straight sections and make precise adjustments in tortuous sections to ensure adequate treatment without compromising overall procedure efficiency.

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.
