Optical Scope Device for Endoscopic Anastomosis Visualization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscopic gastroenteral anastomoses face challenges in targeting the small bowel due to its difficult access and maintaining control of the distal tissue after initial penetration, especially when using balloons or electrocautery for dilation.
Innovation Solution
A system and method involving an optical scope device with an imaging component, a flexible endoscope, a capture device with a loop, and a stent delivery system to form an anastomosis between digestive tract sections, using a guide wire to connect the sections and a stent to maintain tissue apposition and fluid communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a tracking balloon is used to visualize the small bowel, then visualization is improved, but device complexity increases
Solution Approach 1:
The patent extracts the visualization function from complex balloon-based systems and implements it through a simpler scope-based imaging system. The scope device with its imaging component directly visualizes the target site without requiring additional balloons or contrast media, thereby maintaining measurement precision while reducing device complexity.
Solution Approach 2:
The scope device acts as an intermediary tool that provides direct visualization of the small bowel lumen and target site. Instead of using balloons as intermediaries to create contrast, the scope directly images the anatomy, eliminating the need for contrast media and balloon inflation while maintaining visualization quality.
2Ease of operation
If the small bowel is deflated for endoscopic access, then ease of operation is improved, but visualization capability deteriorates
Solution Approach 1:
The scope device enables continuous visualization throughout the procedure. The imaging component captures real-time images of the small bowel lumen and target site, allowing the operator to maintain visualization continuity even when the bowel is collapsed, thereby preserving both ease of operation and visualization capability.
Solution Approach 2:
The patent replaces the mechanical contrast-based visualization system (balloons and contrast media) with an optical imaging system. The scope device uses light-based imaging to visualize the collapsed bowel lumen, substituting mechanical expansion methods with optical detection methods that work effectively in deflated conditions.
3Strength
If balloons or electrocautery are used for dilation, then penetration capability is improved, but control of distal tissue deteriorates
Solution Approach 1:
The scope device serves as an intermediary tool that provides continuous visual feedback during tissue penetration. The imaging component allows the operator to see the needle or instrument advancing through the tissue in real-time, maintaining control of the distal tissue while achieving effective penetration, thereby resolving the contradiction between penetration capability and control.
Solution Approach 2:
The imaging component provides real-time visual feedback during the penetration process. The operator can observe the advancing instrument and tissue response through the scope's images, allowing for continuous adjustment and maintenance of control over the distal tissue while achieving necessary penetration depth and force.

AI summary
A system for forming an anastomosis between first and second sections of a digestive tract includes Optical Scope Device (“OSD”) having a lumen extending therethrough and positioned at a first target site within the first section, OSD including an imaging component at a distal end thereof for viewing the first target site; First Endoscope (“FE”) including a working channel extending therethrough and positioned at a second target site within the second section; Capture Device (“CD”) extending from a proximal end to a distal end including a loop, CD extends through the lumen; First Flexible Element (“FFE”) extends through FE, FFE including a coupling element which passes through the loop to couple FFE to CD, connecting the first and second sections, the coupling element moving between insertion and locking configurations; and Stent having a lumen extending therethrough which provides fluid communication between the first and second sections.
