A sterile drape is provided to cover medical equipment. The drape may include an expandable element to open the open end of the drape. A sheath may also be provided to cover the sheath prior to use. The drape may also be held in a container, which may be coupled to the equipment. Furthermore, the drape may include one or more partially deployed positions in which the drape is partially deployed yet the sterile surface of the drape remains unexposed so that the drape may be partially deployed by non-sterile personnel and stored in a non-sterile area.
