DonJoy Inc. is a global medical technology firm based in California, and one of the many manufacturers of defective shoulder pain pumps. DonJoy makes two different kinds of the pump, the Accufuser Plus and the DonJoy Pain Control Device. Studies have concluded that certain applications of these pumps may cause a disabling condition called Postarthroscopic Glenohumeral Chondrolysis (PAGCL). Pain pumps provide a continuous flow of medication to the surgical site and patients detach the pump once their pain has been alleviated. Pain pump manufacturers like DonJoy were never granted permission by the Food and Drug Administration to directly insert pain pumps into the shoulder joint; the FDA only approved placement of the pump in the tissue. Without FDA approval for direct application in the shoulder joint, DonJoy still promoted its products to surgeons. The manufacturer is now facing more than a few negligence lawsuits.
