Use of the GUIDEZILLA™ II Guide Extension Catheter in Order to Deliver Stents in Tortuous and Calcified Distal Lesions
“As a dedicated CTO operator on the one hand and a convinced “transradialist” on the other, minimally invasive procedural aspects sometimes have to be traded against increased backup in order to treat long, heavily calcified lesions.”
“Among the tools that really have augmented my interventional toolbox, there is the recently launched GUIDEZILLA™ II that comes along with a full size matrix of 6, 7 and 8 French.”
“… Its hydrophilic coating allows it to be delivered even through complex, tortuous anatomies.”
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.
