The tapered core wire can offer excellent delivery performance. Super-lubricity hydrophilic coating can offer a superior delivery performance. Advanced laser bonding technology ensures a smooth transition between the balloon and the catheter to give an excellent crossability. 3-wings balloon fluting ensures the balloon has a minimum profile to cross the stenosis easier. Tip laser forming technology makes the balloon with a small entrance,which gives a good performance of crossability;Soft tapered tip is designed to enhance the trackability of the catheter with the guide wire.
