Intraluminal Device Deployment Without Radiography
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Intraluminal device deployment often requires radiography for precise positioning, which is cumbersome, expensive, and poses risks to patients and practitioners, necessitating a method that can achieve rapid and secure positioning without the need for x-rays or other forms of radiation.
Innovation Solution
A method involving a deployment device with a guidance wall and deployment sheath, guided by a visualization device like a steerable endoscope, allowing the intraluminal device to be unfurled and positioned within a mammalian lumen without radiography, using an actuator to retract the sheath and visualize the device's placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If radiography is used for device positioning, then positioning precision is improved, but procedural complexity and cost increase
Solution Approach 1:
The patent introduces radiopaque markers as intermediary elements that are integrated into the intraluminal device structure. These markers serve as mediators between the device and the radiography system, allowing precise positioning to be achieved through simple radiographic imaging without requiring complex positioning systems or procedures. The markers provide clear visual reference points that simplify the positioning process while maintaining high precision.
2Measurement precision
If radiography is used for device positioning, then positioning precision is improved, but patient and practitioner safety deteriorates
Solution Approach 1:
The patent employs radiopaque markers that are highly visible with minimal radiation exposure. By using markers with high radiopacity, the system achieves accurate positioning with reduced radiation doses compared to traditional radiographic methods. This allows positioning precision to be maintained while minimizing the harmful radiation effects on patients and practitioners.
3Measurement precision
If radiography is used for device positioning, then positioning accuracy is improved, but procedural time increases
Solution Approach 1:
The radiopaque markers are pre-integrated into the intraluminal device during manufacturing, before the deployment procedure. This preliminary integration eliminates the need for separate positioning marker placement steps during the procedure. The markers are already in their final positions on the device, allowing immediate and accurate positioning assessment upon deployment without additional time-consuming steps.

AI summary
A technique for deploying an intraluminal device, such as a bariatric device, in a mammalian lumen, such as the gastrointestinal tract, includes positioning a visualization device through an orifice, such as a natural orifice, into the mammalian lumen. A deployment device having the intraluminal device mounted thereto is guided to the mammalian lumen. The intraluminal device, which has a lumen wall that is configured to the size and shape of a portion of the mammalian lumen, is at least partially deployed from the deployment device in the mammalian lumen. The at least partially deployed intraluminal device is positioned with the deployment device while a position of said intraluminal device is visualized with the visualization device.
