    摘要： Various implementations include implants and related methods for moving bone. Certain implementations include an implant for moving bone in a patient's body, the implant including: an implantable biocompatible housing; a first adjustment rod at least partially overlapping the implantable biocompatible housing; a driver configured to drive the first adjustment rod to enable movement of the first adjustment rod relative to the housing; and a load sensor positioned within the housing and configured to indicate a load applied by the driver on the first adjustment rod.

    摘要： In one embodiment, a non-invasively adjustable spinal system for treatment of a subject having spondylolisthesis includes a first implantable actuator having at least one anchoring structure, the anchoring structure configured to facilitate securement of the first implantable actuator to a portion of the sacrum of the subject. The non-invasively adjustable spinal system can further include an adjustment element, configured to be coupled to the first implantable actuator, the adjustment element having an engagement structure configured to engage at least one transverse process of a lumbar vertebra of the subject. The non-invasively adjustable spinal system can further include a driving element, wherein remote activation of the driving element causes movement of the adjustment element in relation to the first implantable actuator.

    摘要： A device for the non-invasive sensing of the length of an implantable medical device includes animplantable medical device having first and second portions moveable relative to one another and a layer of resistive material disposed on one of the first and second portions. A contact is disposed on the other of the first and second portions, the contact being in sliding contact with the layer of resistive material upon relative movement between the first and second portions. A circuit is configured to measure the electrical resistance along a path including a variable length region of the layer of resistive material and the contact. The electrical resistance can then be converted into a length.

    摘要： An external adjustment device includes at least one permanent magnet configured for rotation about an axis with a first handle extending linearly at a first end of the device and a second handle at a second end of the device, the second handle extending in a direction substantially off axis to the first handle. The external adjustment device further includes a motor mounted inside the first handle and a first button located in the proximity to one of the first handle or the second handle, the first button configured to be operated by the thumb of a hand that grips the one of the first handle or second handle. The first button is configured to actuate the motor causing the at least one permanent magnet to rotate about the axis in a first direction.

    摘要： Aspects of the disclosure relate to an adjustable implant configured to be implanted into a patient that includes an adjustable portion moveable relative to a housing. The adjustable implant may include various smart components for enhancing operation of the implant. Smart components may include a controller for managing operations and a transducer for communicating ultrasound data with an external interface device. Additional smart components may include a load cell within the housing for measuring an imparted load; a sensor for measuring angular position of the adjustable portion; a dual sensor arrangement for measuring imparted forces; a reed switch; a half piezo transducer; and an energy harvester.
