ACIST Medical Systems is known for its innovations in contrast delivery systems for medical imaging, particularly in the field of cardiology. The "ACIST NAVVUS RX MICROCATHETER" suggests a microcatheter associated with contrast delivery or imaging guidance. Here are some general considerations for components like microcatheters used in imaging procedures: Contrast Delivery: Microcatheters are often used in conjunction with contrast media to enhance visibility during medical imaging procedures, such as angiography. Navigation: The term "NAV" in "NAVUS" suggests navigation, which could indicate that the microcatheter is designed for precise and controlled navigation within blood vessels or specific anatomical structures. RX: The "RX" designation often denotes a product intended for diagnostic or therapeutic interventions. Imaging Modalities: Microcatheters are commonly used in procedures like angiography, where detailed imaging of blood vessels is required.
