ABSTRACT:
An apparatus for sealing an environment defined by a periphery is provided. The sealing apparatus includes a first frame defining an opening and being disposed on the periphery of the environment and a second frame defining an opening. A flexible material is rotatably interconnected between the first frame opening and the second frame opening to form an iris aperture. The size of the iris aperture can be adjusted by rotating the second frame with respect to the first frame. The first frame may be secured with respect to the second frame in order to fix the size of the iris aperture. For securing the frames with respect to one another, hook and loop fastening material may be provided. The environment and periphery may, for example, be a surgical patient and a surgical drape, respectively.
