Abstract
A sealing element for a tubular member such as an endotracheal tube which includes a circular collar portion and a pliable flange or gill. One or more of the sealing elements are positioned on a tubular member such as an endotracheal tube. When the tubular member is inserted into a lumen such as a trachea, the pliable flange(s) or gill(s) forms a seal between the outer wall of the tubular member and the inner wall of the lumen. In the case of endotracheal tubes the sealing elements replace conventional inflatable cuffs and allow for tubes having diameters less than 5 mm.
