Prepackaged collections of the devices and supplies (either custom or standard) needed for preparing the patient and delivering an injection of a contrast medium into the joint space in order to visualize a joint by radiographic study (i.e., arthrography). Items in these kits usually include a syringe, needles, a contrast medium (e.g., iodine), a local anesthetic, and cotton pads. The kits are frequently supplied in supporting trays (i.e., procedure trays) consisting of a flat-bottomed receptacle with a border around the periphery supporting all the instruments and supplies needed for the procedure; the trays are usually covered or wrapped. Arthrography procedure kits and trays are intended for use in hospitals and other healthcare facilities to allow visualization of the articular space by injection of a contrast medium (e.g., to determine the cause of unexplained joint pain).
