An artery stabilizer device is provided for stabilizing an artery while a technician inserts a needle into the stabilized artery. Two stabilizer fingers are provided to hold an artery in place while a needle is passed between two extensions and further inserted into the artery beyond the stabilizer fingers; the device can be removed from the worksite while the tip of the needle remains lodged within the artery. A platform is disposed above the stabilizer fingers and extensions create ample distance between the stabilizer fingers and the platform for simplified palpation and improved visibility and safety. Each embodiment can create an augmented pulse at a targeted needle insertion site, making it easier for a technician to palpate the patient's pulse there. Arterial catheter insertions can be facilitated using this invention.
