The Amplatz Super Stiff, or Amplatz guidewire, is a widely utilized stiff rail wire. It possesses properties that enable excellent trackability, stable exchange, and effective deployment of heavy devices.
It was designed to succeed the Lundquist guidewire, the stiffest wire available in 19861.

Properties
The Amplatz wire exhibits a hydrophobic super stiff shaft that seamlessly transitions into a flexible, floppy tip. This design feature enhances the wire's resistance to bending and minimizes the risk of vessel damage when deploying heavy devices 2.

Length: from 75 cm to 260 cm
Tip shapes:
straight
J-tip configuration
Bentson-type configuration
Indication
All procedures that require the use of balloons, stents, or drainage catheters.
Vascular procedures
angioplasty and stenting in aortoiliac occlusive disease
intra-aortic balloon pump placement
Hepatobiliary
biliary stenting / endoprosthesis placement
Gastrointestinal and emergencies
Urogenital
Precautions
The Amplatz guidewire should not be used as a navigation wire as it may lead to vascular or biliary injury due to it's inherent stiffness and hydrophobic shaft.
