ABSTRACT:
A method of forming a fenestrated extremity surgical drape includes providing improved seal integrity to reduce the occurrence of pathogenic contamination at the surgical site via migration through the seal. The seal has a non-linear configuration to eliminate uneven stress concentrations commonly located at the corners of rectilinear seals. An elastomeric apertured panel can be disposed between a film panel and a fiber/film laminate panel. These layers can be joined by a heat sealing operation along two spaced apart concentric seal locations ringing the aperture and a fenestration in the laminate panel. The assembly can then be affixed by adhering the underside(s) of one or more panels to a base drape, which has an opening aligned with the aperture and fenestration.
