Boston Scientific Guidezilla II 7FR

Boston Scientific GUIDEZILLA™ II 7Fr Guide Extension Catheter

The Boston Scientific GUIDEZILLA™ II 7Fr Guide Extension Catheter is a single-lumen, rapid-exchange guide extension catheter designed to provide additional back-up support and facilitate smoother delivery of balloons, stents, and other interventional devices during complex PCI procedures. Boston Scientific describes the device as creating a smooth pathway for balloon and/or stent delivery by combining greater flexibility with a smooth surface.

Engineered for challenging coronary anatomy, the GUIDEZILLA II 7Fr is intended to support device delivery in cases involving calcified lesions, tortuous vessels, and distal lesions, where extra guide support may be needed. Boston Scientific states that the device is designed to help turn difficult or unsuccessful device delivery into a more predictable and successful PCI workflow.

The 7Fr version is part of the expanded GUIDEZILLA II size matrix and features a 0.063 in (1.60 mm) inner diameter, 0.073 in (1.86 mm) outer diameter, and 150 cm working length. Boston Scientific product information also highlights design elements such as a hydrophilic coating for smoother device interaction and a platinum iridium helical collar intended to improve visibility and support smooth transition during device delivery.

Built for interventional cardiology applications, the GUIDEZILLA II guide extension catheter acts as an extension to a traditional guide catheter, helping physicians achieve deeper intubation support and improved deliverability in complex coronary interventions. Its rapid-exchange construction is designed to integrate efficiently into catheterization lab workflows while maintaining procedural control in demanding anatomies.
