Claim 1
Independent Claim
200 words
A sterile drape for performing a plurality of separate surgical procedures on a patient''s body, comprising: a flexible main sheet having a lower and an upper surface respectively contacting and facing away from the patient''s body after placement of the drape, said main sheet having a plurality of individually shaped fenestrations located in the drape and of a sufficient size for performing a plurality of individual surgical procedures through the drape; a plurality of flexible cover sheets removably secured to the upper surface of the drape around said fenestrations to maintain a sterile barrier over said fenestrations, each of said cover sheets being sufficiently large to cover an associated fenestration, with a lower central portion of the cover sheets being non-adherent and facing through the fenestrations, such that an individual cover sheet may be removed from the drape to expose the underlying portion of the patient''s body and perform a selected surgical procedure through its associated fenestration, while the remaining cover sheets maintain a sterile barrier over the remaining fenestrations during the selected surgical procedure; and a plurality of separate flexible reinforcement strips secured to the main sheet, each of said reinforcement strips extending peripherally around one of said fenestrations.
