The modular platform consists of an independently movable dual-catheter system. The daughter catheter is pre-threaded through a sleeve on the mother catheter. The sleeve located proximally to the partially crimped stent ensures co-axial movement of the catheters. Please note that the mother and daughter catheters move independently prior to the deployment of the stent. The ultra-low profile dual monorail system is designed to mitigate wire wrap. Primary inflation of the Sidebranch balloon orients the stent to the side branch. Alignment, phase shift, and orientation are automatic. The stent is flared into the ostium of the sidebranch. With guaranteed sidebranch access, provisional stenting of all bifurcations can be undertaken regardless of the extent of disease in the sidebranch. The use of this system does not require a new skill set by the implanting physician
