The femoral artery is located in the triangle-shaped area at the top of the thigh just below the groin and was the first location to be used for vascular procedures. Because of this, the tools to access this artery have been around the longest, have the widest variety of shapes and sizes, and are the most well studied. This is a large major artery and can be safely and easily accessed by a trained physician either with or without ultrasound guidance.
