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.
