Abstract
A method of applying a medicinal substance onto an area within a patient's body cavity includes providing an applicator formed by six integral sections. A proximal section is formed with an entry passage. An axial intermediate passage of the applicator extends from the entry passage through a flange section and a passage section. A slot section has a slot delivery passage communicating with the axial intermediate passage, and at least one axially-elongated slot therethrough. A solid section extends from the slot section, and a dome section extends to an end of the applicator. The method further includes locating the slot delivery passage adjacent the area within the cavity, forming a substance mass externally of the cavity, moving the mass into the slot delivery passage, and moving at least a portion of the substance onto the area.
