Oesophagi TRIZ Cases
- Anti-Reflux Valve With Rotating Plate for GERD Surgery Prediction
A temporary anti-reflux valve uses a one-way rotating plate to block stomach reflux and predict GERD surgery benefit without invasive pre-surgical tests.
- Intraluminal Device Fixation via Tissue Bridging Connector
Segmented connectors resist distal migration while enabling safe explantation through bioabsorbable degradation and tissue bridging.
- Gastrointestinal Implant Resistive Feature for Satiety
A gastrointestinal implant creates a resistive feature to slow gastric emptying, reducing food consumption without invasive surgical complications.
- ECM Scaffold for Gastroesophageal Junction Reinforcement
Extracellular matrix scaffolds reinforce anastomotic sites to minimize scar tissue formation and reduce leakage rates during esophageal reconstruction.
- Eversion Resistant Gastrointestinal Sleeve Design
Composite sleeve with textured anchor resists eversion under retrograde pressure, preventing digestive tract obstruction.
- Segmented Esophageal Replacement Device with Stent Rings
A two-layer esophageal replacement device uses stent rings to anchor and maintain patency across stump ends.
- Intraluminal Device Core Fixation Against Peristalsis
Removable core allows tissue ingrowth for stability while fasteners prevent distal migration during peristalsis.
- Intestinal Sleeve Bypass for Gut Microbiota Modulation
An implantable intestinal sleeve bypasses the proximal small intestine to alter microbial balance.
- Permeable Bariatric Sleeve with Distal Weight Anchor
A permeable bariatric sleeve allows essential nutrient diffusion while blocking food, resolving malnutrition risks from impermeable designs.
- Implantable Oesophageal Prosthesis With Moving Pressurizing Member
A moving pressurizing member generates continuous peristaltic pressure along an implantable feeding tube.
- Adjustable Gastric Bypass Apparatus with Inflatable Regulators
An adjustable gastric bypass apparatus uses inflatable regulators to control primary and bypass flow profiles through distinct conduits.
- Flexible Gastrointestinal Sleeve for Bariatric Fistula Treatment
A collapsible flexible sleeve anchors in the esophagus to shield fistulas from food contact.
- Endoscope-Deployed Sleeve for Gastrointestinal Nutrient Isolation
An inverted sleeve delivers through an endoscope to isolate nutrients, avoiding surgical complications.
- Magnetic Stomach Volume Reduction via Non-Surgical Implant
Non-surgical magnetic implants reduce stomach volume by attracting wall portions, avoiding invasive surgical risks and procedural trauma.
- Intestinal Bypass Sleeve Anchoring via Expandable Anchor
Expandable anchor secures intestinal bypass sleeve at pylorus, preventing migration while minimizing tissue necrosis risk.
- Pyloric Obesity Valve Flow Resistance Design
Segmented valve design with reduced cross-section resists chyme passage through the pylorus, delaying gastric emptying without invasive surgery.
- Intestinal Flow Modulator for Obesity Treatment
An intestinal flow modulator adjusts chyme speed to reduce nutrient absorption.
