摘要：
The present application describes a coaxial guide coil catheter device to be placed inside of a standard cardiovascular guide catheter for facilitating extra support in the coronary artery when advancing interventional cardiology devices such as balloon catheters and stent delivery systems. This device is passed through the main lumen of a standard guide catheter so that the tip of the coaxial guide coil device is extended past the tip of the guide catheter and into the coronary artery. The proximal portion of the coaxial guide coil will remain within the guide catheter. The device improves the ability of the guide catheter to remain seated in the coronary ostium during interventional procedures.
