Abstract: The medical device has an element including two discs, small (5) and large (6), joined by a central part (7), the structure of the element being determined by a nitinol core (8) with sufficient flexibility to be folded over itself and inserted in a flexible instrument (9) suitable for incorporation in an endoscope or similar device. Also included is a layer (10) of soft material, such as polyurethane, silicone or another polymer that covers the core (8). The core (8) is filamentous and forms at least the two discs (5, 6) via spokes (81) and the central part (7) via a rod (82).

Abstract: A method for positioning a cannula for permanent implant through the orifice or tracheostoma in a fully aligned manner with the help of an inserter. The inner end or suprastomal extension of the cannula, upon withdrawing the inserter is vertically positioned in the supra-ostial area of the trachea, allowing, once the permanent cannula has been permanently positioned, the introduction of a perforated cannula having a characteristic curvature therethrough. The perforated cannula is oriented, through the lower aperture of the permanent cannula -1-, towards the interior of the lungs in order to allow insufflation of air from the exterior, while the exhaled air is derived through the vertical extension towards the larynx through the orifices disposed in the curvature elbow thereof.

Abstract: Consists of positioning, through the orifice or tracheostoma -9-, a cannula for permanent implant -1-, in a fully aligned manner with the help of an inserter -6-, whereby the inner end or suprastomal extension -4- of the cannula -1-, upon withdrawing the inserter -6- vertically positioned in the supra-ostial area -10- of the trachea -8-, allowing, once the aforementioned permanent cannula -1- has been permanently positioned, the introduction of a perforated cannula -11- having a characteristic curvature therethrough, oriented, through the lower aperture -3- of the permanent cannula -1-, towards the interior of the lungs in order to allow insufflation of air from the exterior, while the exhaled air is derived through the vertical extension -4- towards the larynx through the orifices -13- disposed in the curvature elbow thereof.
