The ReFlow System Mini is not intended to change the diagnosis, treatment, or follow-up of patients with proximal catheter occlusions. Under the care, direction, and instruction of the treating physician, the ReFlow System Mini may be used as directed for noninvasive flushing by a trained healthcare professional in-clinic or by a trained caregiver or adult patient in a non-clinical environment.
