Adjustable implant and method of use
First Claim
1. A system comprising:
- an adjustable implant configured for implantation within a subject, the adjustable implant comprising a first permanent magnet, wherein the first permanent magnet has a first axis of rotation, the first permanent magnet operatively coupled to a drive transmission configured to alter a dimension of the adjustable implant;
an external adjustment device configured for placement on or adjacent to the skin of the subject, the external adjustment device comprising a second permanent magnet, wherein the second permanent magnet has a second axis of rotation, and a third permanent magnet, wherein the third permanent magnet has a third axis of rotation, and wherein the first axis of rotation, second axis of rotation, and third axis of rotation are spaced apart; and
wherein cooperative rotation of the second permanent magnet about the second axis and rotation of the third permanent magnet about the third axis result in rotation of the first permanent magnet about the first axis.

Abstract
A system includes an adjustable implant configured for implantation internally within a subject, the adjustable implant comprising a first permanent magnet configured for rotation about a first axis, the first permanent magnet operatively coupled to a drive transmission configured to alter a dimension of the adjustable implant. The system further includes an external adjustment device configured for placement on or adjacent to the skin of the subject, the external adjustment device comprising a second permanent magnet configured for rotation about a second axis and a third permanent magnet configured for rotation about a third axis different from the second axis; and wherein cooperative rotation of the second permanent magnet about the second axis and rotation of the third permanent magnet about the third axis result in rotation of the first permanent magnet about the first axis.
