Product Details

GUIDEZILLA II Guide Extension Catheter creates a smooth pathway for balloon and/or stent delivery by providing greater flexibility and a smooth surface. This is important with complex lesions, calcium, tortuous vessels, and distal lesions. 

By supporting the delivery of the interventional devices that are necessary to complete the procedure, GUIDEZILLA II Guide Extension Catheter will benefit the patient and hospital by turning an unsuccessful PCI into a successful PCI.
