Title
(EN) ATTACHABLE TWO-CHAMBER BREAST PROSTHESIS
(FR) PROTHESE MAMMAIRE AMOVIBLE A DEUX CHAMBRES
Abstract
(EN)
An attachable two-chamber breast prosthesis includes two volumes of silicone materials that have different degrees of softness. The prosthesis includes three pieces of polyurethane film (a front film, a middle film, and a rear film) that form a front chamber and rear chamber. The periphery of the front chamber is smaller than the periphery of the rear chamber. The rear chamber, which contains the firmer silicone material, extends to the peripheral edge of the prosthesis. The front chamber, which contains the softer silicone material does not extend all the way to the peripheral edge along the upper region of the prosthesis. By increasing the thickness of the rear chamber along a boomerang-shaped region defined by the peripheries of the front and rear chambers, the firmer silicone material in the rear chamber provides the prosthesis with proper support and reduces the tendency of the prosthesis to pull away from the skin along to the top edge of the prosthesis.
(FR)
La présente invention concerne une prothèse mammaire amovible à deux chambres qui comporte deux volumes de matériaux siliconés présentant des niveaux différents de souplesse. La prothèse est constituée de trois pièces de film de polyuréthane (un film antérieur, un film intermédiaire et un film postérieur) qui délimitent une chambre antérieure et une chambre postérieure. Le périmètre de la chambre antérieure est inférieur au périmètre de la chambre postérieure. La chambre postérieure, qui est chargée d'un matériau siliconé plus ferme, confine au bord périmétrique de la prothèse. La chambre antérieure, qui contient un matériau siliconé plus souple ne confine pas partout au bord périmétrique de la prothèse. En renforçant l'épaisseur de la chambre postérieure le long d'une zone en forme de boomerang définie par les périmètres des chambres antérieure et postérieure, le matériau siliconé le plus ferme de la chambre postérieure confère à la chambre postérieure un maintien approprié et réduit la tendance de la prothèse à se dégager de la peau le long du bord supérieur de la prothèse.
