The OptiVantage DH Injection System is a contrast delivery system and is designed to inject radiopaque contrast media into a patient's vascular system to obtain diagnostic images when used with computed tomography equipment. The J-Bow component is used to connect the powerhead to a suspension system.

On April 18, 2008, Mallincrodt Inc. issued an Urgent Device Correction letter informing customers to check their inventory, and determine if they have any defective system units. If they observe any loose screws, sheared screws and/or elongated opening(s) around the screws, they are to immediately take the system out of service and contact the firm's service representative. Covidien's customers were all asked to inspect their inventories and to complete an 'Effectiveness Check Return Form' whether or not the product is defective. However, only those system units observed to have loose screws, sheared screws, and/or elongated openings around the screws, will be scheduled to receive correction by a Covidien Service Representative.
