    摘要： According to some embodiments, systems and methods of ultrasonic detection of implantable medical device distraction are provided. The system includes a first elongate member and a second elongate member. The first elongate member has a first end that is configured to be attached to a first location on the skeletal system of a subject, a second end, and at least one landmark identifiable using ultrasound. The second elongate member has a first end that is movably coupled to the second end of the first elongate member, a second end configured to be attached to a second location on the skeletal system, and at least one landmark identifiable using ultrasound. Movement of the first elongate member in relation to the second elongate member causes a corresponding movement of the at least one first landmark in relation to the at least one second landmark which can be detected using ultrasound.

    摘要： A distraction system includes a distraction rod having one end configured for affixation to at a first location on patient. The system further includes an adjustable portion configured for placement in the patient at a second location, the adjustable portion comprising a housing containing a magnetic assembly comprising a magnet, the magnetic assembly secured to a threaded element that interfaces with an opposing end of the distraction rod. The system includes a magnetically permeable member in proximity to the magnetic assembly and covering an arc of less than 360° of the adjustable portion.

    摘要： 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.
