Title
(EN) FIXATION DEVICE AND ASSOCIATED APPARATUS
(FR) DISPOSITIF DE FIXATION ET APPAREIL ASSOCIE
Abstract
(EN) A fixation device (200) to be applied and secured to a bodily tissue is provided. Such a fixation device is comprised of shape-memory material, formed into a first shape corresponding to a fixation device configuration when secured to the bodily tissue, and then plastically deformed into a second shape corresponding to a fixation device configuration for allowing the fixation device to be inserted into the bodily tissue. First, the fixation device, in the second shape, is inserted into the bodily tissue. A stimulus is then applied to the fixation device, after insertion thereof into the bodily tissue, wherein the stimulus is capable of causing a material phase change in the shape-memory material, which changes the fixation device from the second shape to the first shape and thereby secures the fixation device to the bodily tissue. A surgical device comprising a surgical member and a plurality of such fixation devices is also described. The surgical member can be, f. ex. an annuloplasty band or a valve device.
(FR) La présente invention se rapporte à un dispositif de fixation (200) destiné à être appliqué et fixé à un tissu corporel. Un tel dispositif de fixation est constitué d'un matériau à mémoire de forme, qui peut adopter une première forme correspondant à une configuration du dispositif de fixation lorsqu'il est fixé au tissu corporel, et qui subit ensuite une déformation plastique pour adopter une seconde forme correspondant à une configuration du dispositif de fixation et permettant à ce dernier d'être introduit dans le tissu corporel. Le dispositif de fixation, dans sa seconde forme, est tout d'abord introduit dans le tissu corporel. Un stimulus, par exemple de la chaleur, est ensuite appliqué sur le dispositif de fixation après que ce dernier a été introduit dans le tissu corporel, ledit stimulus pouvant provoquer un changement de phase du matériau à mémoire de forme, ce qui fait passer le dispositif de fixation de la seconde forme à la première forme et fixe ainsi le dispositif de fixation au tissu corporel. L'invention a également trait à un dispositif comprenant un élément chirurgical et une pluralité de tels dispositifs de fixation. Ledit élément chirurgical peut être, par exemple, une bande d'annuloplastie ou un dispositif valve.
