Abstract
A method of forming a balloon for a surgical access device includes positioning a molding material into a channel defined in a first mold half of a mold and mounting a second mold half onto the first mold half to cover the channel and form a cavity within the mold. The first and second mold halves each includes vent holes extending therethrough that are in fluid communication with the cavity. The method also includes expanding the molding material to conform to the shape of the cavity to form a balloon including protrusions extending radially outwardly therefrom. The protrusions are formed by engagement of the molding material with the vent holes.
