Multi-Lumen Catheter TRIZ Cases
- Self-Expandable Tube Esophageal Seal for Aspiration Prevention
A self-expanding tube forms a sealing membrane in the esophagus to block gastric reflux during feeding.
- Catheter Assembly with Transitioning Lumens for Sensor Isolation
Transitioning lumens in a catheter assembly isolate sensors from blood flow, preventing occlusion and enabling reliable physiological parameter detection.
- Variable Injection Flow Catheter with Movable Elongate Member
A catheter employs a movable elongate member to modulate fluid flow, maintaining heat transfer effectiveness despite dynamic physiological conditions.
- Intraoperative Cardiac Injection System with Vacuum Stabilization
A steerable catheter uses vacuum suction to anchor the end effector against moving cardiac tissue for precise therapeutic agent delivery.
- Catheter Optical Element for Axial EMR Delivery
An integrated optical element directs visible light through a catheter lumen to inactivate pathogens and stimulate tissue healing without damaging living cells.
- Dynamic Body Cavity Drainage Tube for Single-Point Access
A dynamic drainage tube moves its distal end within a body cavity using fluid pressure or wire manipulation, eliminating multiple incisions.
- Porous Fluoropolymer Catheter Tubing with SLIPS Coating
A porous fluoropolymer catheter tubing infused with a fluorinated liquid creates a slippery surface that resists biological deposits.
- UV Plasma Irradiation Box for Selective Pathogen Inactivation
A UV light box with a plasma diffuser selectively irradiates extracted blood plasma to inactivate pathogens.
- Ureteral Catheter Connection Device with Tether Restraint
An internal tether prevents unintentional release of the connector element from the sleeve during positioning, ensuring secure placement.
- Catheter Micropump Time Division Multiplexing
Micropumps mounted at a catheter proximal end convey medical fluids through a single lumen using time division multiplexing.
