Image-Guided Extraluminal Occlusion Delivery Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical procedures for occluding anatomical structures lack the ability to perform extraluminal occlusions without direct visualization, which can be invasive and require surgical exposure or laparoscopy, limiting the precision and accessibility of temporary or permanent occlusions.
Innovation Solution
A method and apparatus for image-guided extraluminal occlusion using a delivery device introduced percutaneously, guided by near-real-time imaging to deploy occlusion instruments outside the lumen of anatomical structures, allowing for temporary or permanent occlusion without direct visualization, using various occlusion instruments such as inflatable balloons, clamps, and clips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If extraluminal occlusion is performed with surgical exposure or laparoscopic visualization, then direct visualization of the structure is achieved, but the procedure becomes invasive and requires surgical exposure
Solution Approach 1:
The patent introduces imaging systems (fluoroscopy, ultrasound, CT, MRI) as intermediary tools to visualize the anatomical structure and delivery device during the procedure. These imaging modalities serve as mediators between the operator and the target structure, enabling extraluminal occlusion without direct surgical exposure while maintaining visualization precision.
2Ease of operation
If percutaneous delivery device is used for extraluminal occlusion, then surgical exposure is reduced, but precise positioning outside the lumen becomes difficult without direct visualization
Solution Approach 1:
The patent employs near-real-time imaging feedback to guide the advancement and positioning of the delivery device. The imaging system continuously provides visual feedback about the delivery device's location relative to the target anatomical structure, enabling precise positioning outside the lumen while maintaining minimally invasive percutaneous access.
Solution Approach 2:
The patent replaces direct mechanical visualization (surgical exposure) with imaging-based guidance systems. Instead of physically exposing the structure to see and touch it, the system uses fluoroscopy, ultrasound, CT, or MRI to substitute mechanical line-of-sight with electromagnetic field-based imaging, enabling precise positioning without direct visualization.
3Manufacturing precision
If near-real-time imaging is used to guide delivery device advancement, then occlusion precision is improved, but the procedure requires complex imaging equipment
Solution Approach 1:
The patent leverages existing multi-functional imaging equipment (fluoroscopy, ultrasound, CT, MRI) that are already widely available in medical settings. These imaging systems serve multiple purposes: guiding delivery device advancement, confirming occlusion placement, and verifying procedural outcomes. By utilizing equipment that already performs multiple functions, the patent achieves high occlusion placement accuracy without adding specialized single-purpose imaging devices.

AI summary
A method for occluding an anatomical structure (such as a vessel or duct) having a lumen comprises: introducing percutaneously into the body of the patient a delivery device; advancing the delivery device to an occlusion site outside the lumen of an anatomical structure; deploying an occlusion instrument from the delivery device; and occluding the anatomical structure with the occlusion instrument. The advance of the delivery device and the deployment of the occlusion instrument are guided by near-real-time imaging of a target region of a body of a patient, the target region including the occlusion site on the anatomical structure. The delivery device is guided to the occlusion site outside the lumen of the anatomical structure, and the structure is occluded with the deployed occlusion instrument engaging the exterior of the structure.
