Patent

CA 2470994

Insertion of a flange (12) on a tubular prosthesis such as a voice prosthesis (100) through a body opening such as a tracheoesophageal fistula is facilitated by forming a thinner section (18) and a thicker section (14) on the flange (12), wherein the thienner secton (18) preferentially folds as the flange (12) passes through the fistula. Retention of the flange (12) in a gel cap is improved by forming a foldable flap extension on a cylindrical flange (12). A tubular tool for insertion of a tubular voice prosthesis (100) through a fistula is also disclosed.

L'insertion d'une collerette sur une prothèse tubulaire telle qu'une prothèse vocale à travers un orifice corporel tel qu'une fistule trachéo-oseophagienne est facilitée par la formation d'une section plus mince sur la collerette qui, de préférence, se plie lors du passage de la collerette à travers la fistule. La retenue de la collerette dans une coiffe de gel est améliorée par la formation d'un prolongement d'un volet pliable sur une collerette cylindrique. L'invention concerne également un outil destiné à l'insertion d'une prothèse vocale tubulaire à travers une fistule.
