Corvida Medical’s Halo closed system drug-transfer device (CSTD) has a strong vial attachment that provides complete fluid and vapor containment in an airtight, leak-proof closed system. Designed for user simplicity and comfort, the device requires few pieces and steps. The CSTD is compatible with existing work procedures, protocols, and disposable equipment, and features a swabbable, raised seal and needle-safe design to prevent accidental injury. The Halo CSTD was recently cleared by the FDA with an ONB product code classification.
