Multi-Lumen Catheter TRIZ Cases
- Opto-Electromagnetic Catheter Hydrogel Crosslinking for Targeted Embolization
A catheter uses photo-crosslinking and electromagnetic control to form hydrogel in situ, limiting migration during targeted embolization.
- Point-of-Injury Intracranial Pressure Stabilization via Venous Access
Venous access measures pressure indirectly and redirects blood to stabilize intracranial pressure while limiting brain trauma and infection risk.
- Dual-Syringe Venturi Mixing for Enriched Medical Suspensions
A dual-syringe Venturi tip replaces impellers and fans to mix and spray enriched medical suspension onto inner lumen walls.
- Dual-Lumen Catheter Tip Detachment for Liquid Embolic Entrapment Prevention
A detachable second tube separates at a controlled zone, allowing simultaneous liquid-embolic and device delivery while limiting catheter entrapment.
- Dual-Lumen Catheter for Low-Recirculation Lung Assist
Separate drainage and return lumens limit oxygenated-blood recirculation while supporting right-ventricle decompression in portable lung assist.
- Expandable Introducer With Radial Expansion for Atraumatic Vascular Access
A bonded flexible region expands with the inner layer to fit varied objects while reducing vascular injury and blood loss.
- Steerable Catheter Handle for Kink-Resistant Multi-Axis Control
An internal track, manifold, and strain relief sheath support fluid control and multi-axis steering with less insertion force.
- Multi-Use Blood Control Catheter Assembly With Spring-Reset Septum
This catheter assembly uses a movable septum and spring return to enable repeated infusions and blood withdrawals without reassembly.
- Dual-Lumen Intraventricular Access for Chronic Infusion and Sampling
A barrier-separated catheter enables continuous drug infusion and CSF sampling while reducing cross-contamination and infection risk.
- Dual-Lumen Catheter With Detachment Zone for Faster Embolization
A dual-lumen catheter speeds embolization through simultaneous delivery and tip detachment.
- Hypotube Hub Bonding Through Openings and Interlock Handling
Openings in the hypotube wall strengthen polymer bonding to the hub, while an interlock tool reduces damage during processing.
- Esophageal Pressure Catheter With Balloon Spacer for Accurate Sensing
This catheter places an inflatable balloon near the pressure sensor to limit wall contact and improve esophageal readings.
- Expandable Mesh-Balloon Spacer for Transcatheter Tricuspid Repair
A catheter-delivered spacer expands into a coaptation surface, helping treat tricuspid regurgitation while avoiding open-heart surgery.
- Composite Cannula Wall Structure for Bending Resistance and Transparency
Glass or carbon fiber reinforcement combines with clear plastic to resist bending without enlarging the cannula.
- Transitioning-Lumen Catheter Assembly for Isolated Sensor Placement
Terminating lumens isolate catheter sensors from bodily fluids during monitoring.
- Cryoablation Catheter With Multilumen Flow Paths for Bent Anatomy
Multiple supply lumens and a distal discharge path support stable cooling as the cryoablation catheter navigates bent anatomy.
- Blood Collection Tubing with Collapsible Pressure Regulation
Collapsible tubing regulates initial flow to reduce hemolysis and vein collapse.
- Dual-Lumen CSF Catheter Filtration for Guided CNS Treatment
Radiopaque catheter markers guide CSF navigation while integrated filtration removes pathogens and enables targeted chemotherapy infusion.
