The arteries that supply blood to the heart are called coronary arteries. Atherosclerosis may occur over time causing plaque build-up, narrowing the lumen, and increasing the risk of a heart attack. Percutaneous Intervention (PCI) procedures are performed to correct this anomaly. The GuideLiner catheter is used to access discrete regions of coronary vasculature and to facilitate the placement of interventional devices. In the animation, we see that the GuideLiner catheter is back loaded onto the previously inserted guide wire. The GuideLiner catheter is then advanced through the hemostasis valve and into the guide catheter. Under fluoroscopy, the GuideLiner is advanced beyond the guide catheter into the desired location within the vessel. During an interventional procedure, the interventional device is backloaded over the existing guide wire and advanced through the GuideLiner catheter, into the desired vascular space. The GuideLiner catheter is also used in diagnostic capacity by injecting a radio-opaque dye to find a blockage in the vessels.
