Bile Ducts TRIZ Cases
- Gallbladder Occlusion Barrier to Prevent Cholecystitis Recurrence
A bile barrier seals the gallbladder interior to block wall contact, reducing calculus formation and recurrent cholecystitis with less invasive treatment.
- Gallbladder-Duodenum Bypass Tube for Low-Invasive Cholecystitis Control
A gallbladder-duodenum fistula and bypass tube reroute bile from the cystic duct to suppress recurrence and calculus formation with less invasiveness.
- Gallbladder-Duodenum Bypass Tube With Anchoring for Recurrence Prevention
Bile is diverted from the cystic duct to the duodenum through a secured bypass tube, reducing invasiveness while limiting stone-related recurrence.
- Implantable Devices With Porous Zinc Layers for Controlled Release
Controlled zinc-ion release from a porous implant coating inhibits smooth muscle cell proliferation while avoiding toxic tissue concentrations.
- Photo-Regenerative Stent With Photolabile Coating for Patency Restoration
A photodegradable layer liquefies under light, decouples from the coating, and restores stent patency without surgery.
- Magnetically-Regenerative Stent with Thermo-Responsive Layer
Magnetic nanoparticles in a stent's thermo-responsive layer liquefy under an external field, removing biofilms and restoring lumen patency without surgery.
- Stent With Selective Membrane Coating for Anti-Migration
Segmented membrane coverage on the stent scaffold anchors the device via tissue ingrowth while preserving an uncovered medial zone for fluid drainage.
- Non-expandable Stent with Curved Proximal Portion and Sphincter Engagement
A non-expandable stent uses a curved proximal portion and distal retaining member to anchor within the biliary duct.
- Biodegradable Filter Device for Biliary and Renal Stone Management
Segmented mesh filters prevent stone migration without radial expansion, reducing surgical interventions for gallbladder and kidney obstructions.
