Guide Wires TRIZ Cases
- Rotational-Axial Guidewire Actuation for Arterial Occlusions
An actuator and chuck apply controlled rotational and axial forces to slick guidewires, helping them advance through tortuous vessels and occlusions.
- Guide Wire Groove Segmentation for Flexibility and Torque
Segmented helical grooves with bridge portions help a guide wire bend easily while preserving torque transmission in blood vessels.
- Robotic Drive System for Multi-Catheter Supra-Aortic Access
Multiple robotic hubs coordinate catheter and guidewire motion, including lateral deflection, for challenging supra-aortic access.
- Piezoelectric Pressure-Sensing Guidewire for Tactile Navigation
A piezoelectric polymer sensor at the guidewire tip converts pressure into signals, restoring tactile feedback for precise endovascular navigation.
- Superelastic Guide Wire With Electromagnetic Sensing for Sinus Dilation
A superelastic guide wire combines distal electromagnetic sensing with image guidance to place balloon dilation catheters precisely and improve sinus drainage.
- Integrated Torque Device and Catheter Assembly for Guidewire Exchange
By combining the torque device with the catheter, the case supports one-handed guidewire handling, position retention during exchange, and material injection.
- Guidewire Coil Pitch Segmentation for Retraction Resistance
Varying outer-layer coil pitch and resin-coating diameter increases vessel-wall friction to keep a guidewire from retracting.
- Medical Device Coil Fixation Against Proximal Folding
A fixation portion near the second coil’s distal end locally increases bending rigidity to prevent proximal folding while retaining flexibility.
- Pressure-Activated Rigidizing Overtube With Hemostasis Valve
Vacuum or pressure stiffens the overtube to limit gastrointestinal looping while its integrated hemostasis valve supports endoscopic access.
- Variable-Stiffness Guidewire for Radiation-Free Cardiac Placement
Differentiated stiffness protects vessels at the tip while electromagnetic tracking supports accurate cardiac placement without fluoroscopy.
- High-Torque Guidewire With Flexible Distal Core and Outer Tube
A tapered distal core and centered outer tube balance torque transmission with bending flexibility during intravascular navigation.
- Endoscopic Accessory Tool Motion Transmission for Atraumatic Cannulation
Electromagnetic actuation guides endoscopic tool distal tips through tortuous anatomies, reducing friction and tissue trauma during cannulation.
- Endovascular Wire and Catheter Disk Holder for Sterile Retrieval
A side-cutout disk holder stores pre-coiled guide wires and catheters, reducing droppage and contamination during endovascular procedures.
