A multi-jointed, upper extremity radial artery procedure support device and associated warming sleeve is disclosed. The support device may function like a human arm and is designed to support both right-sided and left sided interventions. The multi-jointed radial arm support device may allow flexion and extension of a patient's arm at the patient's associated elbow and wrist. The arm-warming sleeve may apply gentle warmth to the patient's arm during a procedure to induce vasodilation of the radial artery, and eliminate a need for vasoactive drugs during radial artery procedures.
