Prescriptive Information

Prior to use, please review the complete Guidezilla Instructions for use.

Intended Use/Indications For Use:

The Guidezilla guide extension catheter is intended to be used in conjunction with guide catheters to access discrete regions of the coronary and/or peripheral vasculature, and to facilitate placement of interventional devices.


• Vessels less than 2.5 mm in diameter. • Vessels in the neurovasculature and the venous system.


• Never advance the Guidezilla device into a vessel without a leading guidewire or without confirming location using fluoroscopic guidance. Vessel dissection or perforation may result. • Due to the size and non-tapered tip of the Guidezilla device, extreme care must be taken to avoid vessel ischemia or vascular damage. • Where there is limited clearance between interventional devices and the distal guide segment lumen, those devices must be advanced and withdrawn slowly with the hemostasis valve open to reduce the risk of embolism. • This is a non-torqueable device. Torqueing the device may result in wire wrap or damage to the device or vessel. • Never advance the Guidezilla device into a vessel with an effective diameter less than 2.5 mm. Vessel injury, ischemia, and/or occlusion may result. If pressure in a vessel dampens after inserting the Guidezilla catheter, withdraw the Guidezilla catheter until the pressure returns to normal.


• Exercise care in handling of the device during a procedure to reduce the possibility of accidental breakage, bending or kinking. • When the device is in the body, it should be manipulated only under fluoroscopy. Do not attempt to move the device without observing the resultant tip response. • Never advance the Guidezilla device more than 15 cm beyond the tip of the guide catheter. Further distal advancement of the Guidezilla device could cause the entire guide segment to track outside of the guide catheter and impede withdrawal of the device. • If strong resistance is encountered during manipulation of the devices, do not force passage. Determine the cause of the resistance before proceeding. If the cause cannot be removed, withdraw all devices simultaneously.

Adverse Events:

The adverse events include, but are not limited to: • Vessel trauma (e.g., perforation, dissection) • Vascular complication (e.g., puncture site complication) • Thrombus • Renal failure • Slow-flow/occlusion • Allergic reaction • Death • Emboli • Hemorrhage/hematoma (e.g., vascular access complication) • Infection • Myocardial infarction • Arterial spasm • Intimal disruption


Federal Law (USA) restricts this device to sale by or on the order of a physician.
