Guide Wires TRIZ Cases
- Hemostasis Valve Control via Sensor Feedback
Sensor feedback automates hemostasis valve control, resolving the trade-off between automation precision and device complexity in catheter systems.
- IV Extension Set With Integrated Patency Guidewire
A translation handle moves the guidewire between retracted and advanced positions to prevent blood vessel blockages during extended IV therapy.
- Helically Wound Coil Lumen Re-entry System
A helically wound coil with a relaxed distal segment and tip deflection wire enables precise lumen re-entry.
- Endoscopic Puncture Needle with Inclined Cutting Edge
Adjustable needle tube position overcomes fixed bending limitations, reducing patient burden.
- Hybrid Wire Guide Flex Transition Voids
Patterned voids in a stainless steel flex transition segment match nitinol flexibility, resolving the pushability and navigability trade-off.
- Multi-Angulated Catheter Radial Approach Design
Segmented multi-angulated catheter resolves insertion difficulty in left ventricle radial approaches.
- Coil Guide Wire Hydrophilic Coating Moisture Pooling
A coil guide wire uses a layered hydrophobic and hydrophilic coating to pool moisture within structural spaces for consistent lubricity.
- Coated Tubular Support Member Sealing Slots Without Stiffening
A sealing layer overlays wall openings in a tubular support member to block fluid egress while preserving device flexibility.
- Medical Guide Wire Torsional Rigidity Optimization
Optimizing torsional rigidity ratios in a three-member connecting structure improves rotation transmission performance to the distal end.
- Functional Hose Instrument Axial Stroke Actuation via Curvature
A functional hose instrument bends its body to create a curvature difference between the sheath and core, generating axial stroke.
