A method and apparatus for forming a composite filler. A composite ply is folded. The composite ply comprises fibers arranged at an angle relative to a central axis of the composite ply such that the composite filler has a varying cross-sectional orientation of fibers. A force is applied to the folded composite ply after folding to form a desired shape for the composite filler.

A multi-layer visor system for a surgical hood or garment is provided. The system includes a base film layer and one or more removable film layers that are coextruded at high temperature to form a sterile surface between each of the film layers should the surgeon elect to peel away a soiled or splattered removable film layer during the course of a surgical procedure so that an unobstructed view can be maintained. Thus, no separate sterilization step is required in order to sterilize the layers of the visor system. Each of the removable film layers can additionally include a tab having distinctive features in order to enable a wearer to easily distinguish between the tabs in order to make it easier for a wearer to know which tab to pull first to remove the outermost removable film layer. Further, because the tabs are located about the perimeter of the removable films, viewing is not obscured, yet the film layers are held securely in place until easily removed from the underlying removable film layer or base film layer.

A heating blade unit, a treatment tool, and a method of manufacturing a heating blade unit are disclosed. The heating blade unit includes: an electric heater, a blade, and a cover made of a thermosetting resin. The blade includes a treatment surface, an installation surface that is provided on a side opposite to the treatment surface and on which the electric heater is installed, and a support surface that is provided at a position different from a position at which the installation surface is provided. The cover integrally covers the electric heater, and one or more surfaces of the blade.
