145cm Roadrunner® is a ureteral catheter guide wire that is used for catheter positioning and exchange in a tortuous or kinked ureter. It is also used in traversing a large stone en route to the kidney. Key Features: This guide wire has a nitinol core that allows maximum deflection without kinking. The platinum tip of this instrument ensures high visualization during fluoroscopy. The One-to-one torque control allows precise navigation throughout the most challenging anatomy. Roadrunner is available in standard and stiff shaft. The AQ® coating of this instrument is a micro thin layer of hydrophilic polymer that helps in creating a low-friction surface. This instrument is not intended for PTCA use.
