  • Publication number: 20260123970
    Abstract: An adjustable implant system configured to non-invasively guide bone growth in a patient. The adjustable implant system includes a tether having a first end coupled to a fixed bone anchor and a second end coupled to an adjustable bone anchor. The adjustable bone anchor includes a driver disposed within a housing and the driver is configured to actuate in response to an externally applied magnetic field. The adjustable implant system includes an external adjustment device configured to non-invasively actuate the driver disposed within the adjustable bone anchor. Non-invasive actuation of the driver can cause the adjustable bone anchor to increase or decrease the amount of tension on the tether.

  • Patent number: 12558133
    Abstract: Provided herein is an adjustable implant configured to non-invasively guide bone growth in a patient. The adjustable implant includes a first portion configured to couple to a first bone segment and a second portion at least partially disposed within the first portion and configured to couple to a second bone segment. The adjustable implant includes a drive assembly configured to be transcutaneously actuated, and to drive rotation of a gear assembly configured to rotate about a first axis, and drive axial translation of the second portion along a second axis. Non-invasive actuation of the drive assembly therefore causes the adjustable implant to distract or retract along the second axis.

  • Publication number: 20240225704
    Abstract: One aspect of the disclosure relates to an extramedullary biocompatible implant for moving bone in a patient's body. In some cases, the implant includes: a first plate configured to be attached to bone at a first location; a second plate configured to be attached to bone at a second location; and a distractor extending from the first plate and being at least partially contained within the second plate, where the distractor houses a drive system including a driver and a gear system coupled with the driver, and where the drive system is configured to cause translation of the second plate relative to the first plate.
