Title
(EN) ANATOMICAL ORIFICE SIZERS AND METHODS OF ORIFICE SIZING
(FR) CALIBRES POUR ORIFICES ANATOMIQUES ET PROCEDE DE CALIBRAGE D'ORIFICES ANATOMIQUES
Abstract
(EN)
Anatomical orifice sizers that are optimally proportional to an associated prosthetic device such as a heart valve, and methods of use are provided. The sizers are desirably slightly larger than the rigid mounting diameter of the corresponding heart valve. The heart valve sizer may be cylindrical and have a diameter about 0.3 mm larger than the valve mounting diameter. The sizer preferably has a length of between about 19 mm to 22 mm, and the edges are desirably rounded to a minimum 1 mm radius. The method includes providing a set of cylindrical sizers having varying diameters; sequentially inserting at least two of the sizers through the annulus; measuring the push force needed to pass each sizer through the annulus; selecting a valve corresponding to the sizer for which the measured push force is between about 150 and 300 grams.

L'invention concerne des calibres pour orifices anatomiques dont les proportions correspondent de façon optimale à un dispositif prosthétique associé tel qu'une valvule cardiaque, ainsi que des procédés correspondants. Les calibres sont de préférence un peu plus larges que le diamètre de montage rigide de la valvule cardiaque correspondante. Le calibre de valvule cardiaque peut avoir une forme cylindrique et posséder un diamètre supérieur d'environ 0,3 mm au diamètre de montage de la valvule. Le calibre a de préférence une longueur comprise entre 19 mm et 22 mm, les bords étant de préférence arrondis à un diamètre minimal de 1 mm. Le procédé consiste à fournir un ensemble de calibres cylindriques possédant des diamètres variables; à insérer l'un après l'autre au moins deux calibres à travers l'anneau; à mesurer la poussée nécessaire pour enfiler chaque calibre à travers l'anneau; et à sélectionner une valvule qui correspond au calibre pour lequel la poussée mesurée est d'environ 150 à 300 grammes.
