A recent US Food and Drug Administration (FDA) warning letter to a device sponsor involves the sponsor marketing a device used for dialysis without an approved application for premarket approval (PMA) or an approved application for an investigational device exemption (IDE). The device was previously cleared through the 510(k) pathway. However, the sponsor made significant changes to the design and function of the device.
