Abstract
Abstract A surgical procedure tray for supporting disposable medical devices in a surgical procedure pack. The tray and components are wrapped with a sterile wrap. The tray includes a substantially flat bottom portion and a border surrounding the periphery of the bottom portion. The border has a series of bends and includes an upwardly extending lip of a predetermined thickness. The distal end of the lip narrows to connect to a thinner rounded elbow which joins a downwardly slanting ledge. The distal end of the ledge is connected to a tip which is connected to a bead. The thinner outer portions and numerous bends of the border flex so that damage to the sterile wrap covering the tray is reduced.
