Abstract: A surgical drape including a flexible sheet having a top surface and an outer edge including distinct given and particular segments, the primary sheet defining a fenestration for accommodating a surgical procedure; a flexible first flap secured to the given segment and shaped and arranged to be foldable over the sheet into a position substantially covering the fenestration; and a flexible second flap secured to the particular segment and shaped and arranged to be foldable over the sheet into a position substantially covering the fenestration. The flaps are deployable to selectively reduce the size of the fenestration.

Abstract: A surgical drape including a flexible bottom sheet having a lower surface of given area for placement on a patient and an upper surface for facing away from the patient, the bottom sheet defining a bottom fenestration of given size for accommodating a surgical procedure. Also included is a flexible top sheet detachably secured to the upper surface of the bottom sheet and covering the bottom fenestration. The top sheet has bottom and top surfaces of predetermined area less than the given area and defines a top fenestration of predetermined size smaller than the given size and aligned with bottom fenestration. A securement mechanism is provided for securing the top sheet around a body appendage after detachment of the top sheet from the bottom sheet. The securement mechanism improves use flexibility of the surgical drape.
