Abstract:
1. A system for changing the dimension of a portion of a subject comprising: an adjustable implant configured for implantation within a patient comprising: a tubular member; an internal magnet disposed within the tubular member, the internal magnet configured to rotate in response to a moving magnetic field originating external to the subject; an adjustable member operatively coupled to the internal magnet, wherein the internal magnet is configured to rotate in response to the moving magnetic field and change a dimension of the adjustable implant as the internal magnet rotates; and a magnetic brake configured for implantation within a patient, wherein, in the absence of the moving magnetic field, the magnetic brake is configured to prevent the internal magnet from rotating, and wherein, in the presence of the moving magnetic field, the magnetic brake is configured to allow the internal magnet to rotate.
