Guide Wires TRIZ Cases
- Interventional Guidewire Torque Device Perpendicular Actuation
A guidewire torque device uses a perpendicular actuator and clamp to couple the wire for precise control.
- Intracardiac Pump Guidewire Loading Lumen Design
A loading lumen extends through an intracardiac pump to guide a guidewire along a defined path.
- Integrated Guidewire Balloon and Electrodes for Sinus Dilation
A guidewire integrates a balloon and electrodes to perform sinus dilation alongside tissue ablation or coagulation.
- Steerable Tip Guide Catheter with Electroactive Polymer Actuators
Electroactive polymer actuators enable programmable shape changes in a steerable guide catheter body, resolving steering difficulties in tortuous vasculature.
- Guidewire With Variable Coil Pitch Sections
Variable coil pitch relieves squeezing to improve rotational followability in curved pathways.
- Slit Guidewire Introducer for Valve Loading
Segmenting the introducer via a slit allows removal without threading, reducing procedural time and complexity.
- Asymmetric Coil Cross-Section for Guide Wire Friction Reduction
A coil with asymmetric cross-section features prevents wire rod sticking and bulging in medical guide wires.
- Pressure Guide Wire Sensor Mounting and Flexibility
A pressure guide wire embeds a sensor in an intermediate ring groove to monitor lumen pressure accurately.
- Steerable Loop Tip Wire-Guide Navigation
Relative wire movement directs the loop away from impediments, enabling navigation into side branches.
- Medical Elongated Body Spiral Slit Torque Transmission
Adjacent convex portions on opposing surfaces of a spiral slit tube disperse stress and rotation force, suppressing twisting while maintaining flexibility.
- Bending Extending Device Belt-Like Flexible Parts Buckling
A bending and extending device uses belt-like flexible parts to slide within an elastic hollow guide unit for controlled motion.
- Medical Guidewire Hydrophilic Coating Sliding Resistance
A medical guidewire core shaft features a cylindrical part coated with hydrophilic material to reduce sliding friction against guiding catheters.
- Welded Nitinol Guide Wire Core Segments
Directly welding dissimilar metal cores eliminates external connector tubes, minimizing the guide wire profile while maintaining connection strength.
- Compression Torque Device for Guidewire Manipulation
A compression torque device uses a pivoting actuator to extend a flexible clamping member into a lumen for precise guidewire control.
- Endoscope Coil Structure with Curved Contact Surfaces
Curved contact surfaces on the wire rod suppress axis misalignment and buckling in endoscope insertion sections.
