The mask at the end of a laryngeal mask assembly is made from a flexible cylindrical member (30). Ledges (32) (33) at the base and top of the cylinder are folded axially to form an annulus with an inner rib 27 formed from the ledges (32) and (33). One side of the rib 27 is located in a channel (36) formed in the elliptical rim of the mounting member 15. The other side of rib 27 is located in a channel (37) around a plate 26, which is attached to the mount member 15 trapping the rib between the plate and the mount member so that a cuff 25 is formed around the mount member. |
