Suction-Cup Needle Puncture for Full-Thickness Gastric Plication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gastric volume reduction procedures are invasive, costly, and pose risks, especially for individuals who are overweight but not morbidly obese, with limited depth of plication and potential damage to surrounding viscera due to lack of visibility during endoscopic procedures.
Innovation Solution
A method and device using a suction device in the form of a cup to safely penetrate the gastric wall by drawing tissue into contact with a needle, allowing controlled penetration with RF or Veress needles, minimizing damage to surrounding tissues and enabling full thickness gastric wall engagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a needle is extended through the gastric wall during endoscopic procedures, then gastric volume reduction is achieved, but surrounding viscera may be damaged due to lack of visibility
Solution Approach 1:
The patent introduces a suction device as an intermediary between the needle and the gastric wall. The suction device captures and holds the gastric wall tissue, serving as a mediator that allows the needle to penetrate the gastric wall without directly contacting surrounding viscera. This intermediary mechanism provides visual confirmation and physical control, eliminating the harm of accidental damage to surrounding organs.
2Ease of operation
If endoscopic procedures are used for gastric restriction, then minimally invasive treatment is provided, but the depth of plication is limited
Solution Approach 1:
The patent employs pneumatic suction through a suction device connected to a vacuum source. This pneumatic mechanism draws the gastric wall into the suction device, enabling the needle to penetrate to the full depth of the gastric wall and achieve adequate plication depth while maintaining the minimally invasive endoscopic approach. The pneumatic suction overcomes the depth limitation of purely endoscopic methods.
3Reliability
If RYGB or complex procedures are performed on overweight individuals, then weight loss is achieved, but the risks and costs outweigh benefits for non-morbidly obese patients
Solution Approach 1:
The patent changes the procedural parameters by using a simplified endoscopic technique with suction-assisted needle penetration, rather than performing complex surgical procedures like RYGB. This parameter change in the approach allows overweight (but not morbidly obese) patients to achieve effective gastric restriction with significantly reduced risks and costs, making the procedure appropriate for a broader patient population.

AI summary
A method for safely penetrating the tissue of a gastric wall includes deploying a tissue puncture assembly including a suction device proximate the gastric wall tissue, applying a vacuum source to the suction device to draw a portion of the gastric wall tissue thereto and extending a needle through the portion of gastric wall tissue drawn into contact with the suction device. A device for safely penetrating the tissue of a gastric wall includes a tissue puncture assembly including a suction device in the form of a cup with suction ports therein and an open end. A needle is surrounded by the cup and extends through the cup toward the open end.
