Abstract

See full text

A laryngeal mask assembly has a mask portion of elliptical shape formed by a mount and an inflatable member attached to the mount. The inflatable member is formed by heat bonding together opposite walls of a flat balloon and at the same time cutting an aperture through the walls, so as to form a central web within an outer inflatable ring. The central web is attached to a concave surface on the forward surface of the mount with the aperture in the web aligned with an opening in the mount.
