A method is disclosed for utilizing a deformable article of manufacture formed at least partly of a shape memory alloy. The method includes the steps of deforming the article from a first predetermined configuration to a second predetermined configuration while the shape memory alloy is, at least partially, in its stable martensitic state and at a first temperature. A resisting force is applied to the deformed article of manufacture using a restraining means and the article is heated from the first temperature to a second temperature in the presence of the resisting force. The stable martensitic state is transformed to a metastable stress-retained martensitic state. The resisting force is then removed allowing the alloy to transform to its austenitic state and the shape of the article to be restored substantially to its first configuration. Devices primarily medical devices operative by employing this method are also disclosed.

L'invention concerne un procédé permettant d'utiliser un article pouvant être déformé formé du moins en partie d'un alliage à mémoire de forme. Ce procédé comprend les étapes consistant à déformer l'article d'une première configuration prédéterminée en une deuxième configuration prédéterminée alors que l'alliage à mémoire de forme est, du moins partiellement, dans un état martensitique stable et à une première température. Une force de résistance est appliquée à l'article déformé au moyen d'un moyen de limitation et l'article est chauffé de la première température à une deuxième température en présence de la force de résistance. L'état martensitique stable est transformé en un état martensitique métastable par maintien de la contrainte. La force de résistance est ensuite éliminée, permettant à l'alliage de se transformer en son état austénitique et à la forme de l'article de retrouver sensiblement sa première configuration. L'invention concerne également des dispositifs, principalement des dispositifs médicaux, fonctionnant par la mise en oeuvre de ce procédé.
