MAGNETIC IMPLANTS AND METHODS FOR RESHAPING TISSUE

Methods and devices for reshaping or reforming tissue, such as a mitral valve (102) of a heart (100), are described. An implant (120) includes a generally flexible body (126) and a plurality of magnetic portions (122, 124) such that the magnetic portions (122, 124) interact to cause a change in the...

Summary:Methods and devices for reshaping or reforming tissue, such as a mitral valve (102) of a heart (100), are described. An implant (120) includes a generally flexible body (126) and a plurality of magnetic portions (122, 124) such that the magnetic portions (122, 124) interact to cause a change in the shape of the implant (120), which, in turn, effects a change in shape of the subject tissue. In one example, at least one implant (120) is positioned within a coronary sinus (104) to affect the shape of the mitral valve annulus (116). The implant (120) may further include fixation mechanisms (702, 704) for securing the implant (120) within a vessel (116) and may provide for removability after desired deformation of the subject tissue has taken place. L'invention concerne des procédés et des dispositifs de remodelage ou de reformation de tissus, tels qu'une valvule mitrale (102) d'un coeur (100). Selon l'invention, un implant (120) comprend un corps généralement souple (126) et une pluralité de parties magnétiques (122, 124), de sorte que les parties magnétiques (122, 124) interagissent afin d'entraîner un changement de forme de l'implant (120), qui, à son tour, entraîne un changement de forme des tissus du sujet. Dans un exemple, au moins un implant (120) est positionné dans un sinus coronaire (104) afin d'affecter la forme de l'anneau mitral (116). L'implant (120) peut également comprendre des mécanismes de fixation (702, 704) destinés à la fixation de l'implant (120) dans un vaisseau (116) et peut être retiré après déformation souhaitée des tissus du sujet.
