  • Publication number: 20200155201
    Abstract: A distraction system includes a first distraction device having a first adjustable portion and a first distraction rod configured to telescope within the first adjustable portion, the first adjustable portion having contained therein a first rotatable magnetic assembly mechanically coupled to a first screw configured to axially telescope the first distraction rod. A second distraction device is provided and includes a second adjustable portion and a second distraction rod configured to telescope within the second adjustable portion, the second adjustable portion having contained therein a second rotatable magnetic assembly mechanically coupled to a second screw configured to axially telescope the second distraction rod. An adjustable joint connects one end of the first adjustable portion to one end of the second adjustable portion.

  • Publication number: 20200038071
    Abstract: 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).
