摘要： A system includes a first pedicle screw, a second pedicle screw, and an adjustable rod having an outer housing coupled to one of the first pedicle screw and the second pedicle screw, the outer housing having a threaded shaft secured to one end thereof extending along an interior portion thereof. The system farther includes a hollow magnetic assembly disposed within the outer housing and having a magnetic element disposed therein, the hollow magnetic assembly having an internal threaded surface engaged with the threaded shaft, the magnetic assembly being coupled to the other of the first pedicle screw and the second pedicle screw, wherein the hollow magnetic assembly rotates in response to an externally applied magnetic field to thereby lengthen or shorten the distance between the first pedicle screw and the second pedicle screw.

摘要： A system includes an adjustable implant configured for implantation internally within a subject and includes a permanent magnet configured for rotation about an axis of rotation, the permanent magnet operatively coupled to a drive transmission configured to alter a dimension of the adjustable implant. The system includes an external adjustment device configured for placement on or adjacent to the skin of the subject having at least one magnet configured for rotation, the external adjustment device further comprising a motor configured to rotate the at least one magnet and an encoder. Rotation of the at least one magnet of the external adjustment device effectuates rotational movement of the permanent magnet of the adjustable implant and alters the dimension of the adjustable implant. Drive control circuitry is configured to receive an input signal from the encoder.

摘要： An interspinous process device is configured for placement between adjacent spinous processes on a subject's spine. The device includes a housing configured for mounting to a first spinal process, the housing having a lead screw fixedly secured at one end thereof. A magnetic assembly is at least partially disposed within the housing and configured for mounting to a second spinal process. The magnetic assembly includes a hollow magnet configured for rotation within the magnetic assembly, the hollow magnet comprising a threaded insert configured to engage with the lead screw. An externally applied magnetic field rotates the hollow magnet in a first direction or a second, opposite direction. Rotation of the hollow magnet in the first direction causes telescopic movement of the magnetic assembly out of the housing (i.e., elongation) and rotation in the second direction causes telescopic movement of the magnetic assembly into the housing (i.e., shortening).
