## Indications for use
The Renegade STCTM 18 Microcatheter is intended for general intravascular use, including neuro, peripheral and coronary vasculature. The catheter can be coaxially tracked over a steerable guidewire in order to access distal, tortuous vasculature. Once the subselective region has been accessed, the catheter can be used for controlled and selective infusion of diagnostic, embolic, or therapeutic materials into vessels.
