The Apex Balloon Catheter offers a new shaft and tip technology along with an expanded size matrix which optimizes the balance between trackability and pushability. These improved features are designed for a greater crossing success* While reaching a complex lesion is important, but crossing it is critical. Hence an optimal balance between pushability and trackability gives the Apex Balloon Catheter the power to push beyond difficult lesions, optimizing chances for a successful stent delivery. The Stiff and flexible Bi-Segment™ Inner Shaft (Monorail® and OTW Catheters) enhances both pushability and trackability* The TruFeel™ Hypotube (Monorail Catheter) is designed to improve kink resistance and has a polymer sleeve for easy handling and device integrity. The Slope™ Outer Shaft (OTW Catheter) is a seamless one piece shaft made of new nano-composite material designed to enhance push efficiency
