Guide Wires TRIZ Cases
- Arterial Occlusion Implant and Catheter for Targeted Subintimal Delivery
An inflatable-balloon catheter guides an implant into the arterial subintimal space for controlled occlusion and reduced thrombus formation.
- Medical Guide Wire Hardness Gradient for Resilient Navigation
Wire drawing and tension annealing create a hardened outer region that supports guide wire resilience, shape restoration, and navigation.
- Left Atrial Appendage Closure Visualization Catheter Magnetic Guidance
A ferrous guidewire and catheter magnets guide visualization through the atrial septum, improving alignment and minimizing trauma.
- Robotic Percutaneous Device Exchange for Stationary Guidewire Control
A movable base and guidewire positioner coordinate catheter exchange while keeping the guidewire stable relative to the lesion.
- Catheter Construction with Gradual Durometer Transitions for Torque Stability
Composite polymer sections create a durometer gradient that balances catheter flexibility, axial strength, torque control, and navigation.
- LIMA Crossover Catheter Geometry for Right-Radial Cannulation
A shaped guide catheter and telescoping inner sheath address difficult LIMA engagement across varied aortic arch geometries.
- Catheter Adapter Side-Port Guide for Smoother Instrument Delivery
A catheter adapter uses a sub-45° side port with a wedge or insert to guide instruments, reduce resistance, and limit assembly disruption.
- Micro-Medical Guidewire Magnetic Tip Control for Vascular Angles
Spaced magnetic bodies enable precise tip steering while the outer coil preserves guidewire flexibility and torqueability.
- Microcatheter Distal Tip Structure for Narrow Vessel Navigation
A reinforced proximal body and flexible distal tip help the microcatheter enter narrow vessels while reducing bending resistance.
