ADJUSTABLE IMPLANT SYSTEM

摘要

An adjustable medical system includes an adjustable implant having an adjustable portion configured to the change dimension or orientation of an internal portion of a mammal and a driven portion comprising a magnetically responsive element configured for rotation about an axis of rotation. The system further includes an external adjustment device configured to magnetically couple to the driven portion from a location external to the mammal, the external adjustment device comprising a first permanent magnet configured for rotation about a first axis and a second permanent magnet configured for rotation about a second axis different from the first axis. Cooperative rotation of the first permanent magnet about the first axis and rotation of the second permanent magnet about the second axis result in rotation of the magnetically responsive element about its axis of rotation.
