Abstract
A surgical drape is made from a pair of rectangular panels of drape material which are interconnected at a separation zone so that the panels to be pulled apart following a procedure. A fenestration is punched out of the material of one of the panels, near the perforated zone. The fenestration is covered by a flexible, transparent plastic window, preferably made of a polyethylene film and the perimeter of the window is bonded to the drape panel around the fenestration. The window is larger than the fenestration, and is folded or gusseted at its corners so that its center can rise well above the plane of the fenestration, in order to provide clearance for instruments which may be protruding from a surgical site over which the drape is placed.
