    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: Disclosed herein are lock mechanisms configured for locking and unlocking rotation of a driver and a driven gear system in implantable distraction and compression systems, and implantable medical devices and implantable distraction and compression systems including such lock mechanisms. The lock mechanisms include a keeper that is configured to move from a locked position to an unlocked position in response to a rotation of the driver, wherein, in the locked position, the keeper is configured to resist rotation of the driven features and the driver under a load on the driven features, and in the unlocked position, permits rotation of the drive gear and the driver.

    摘要: In one embodiment, an adjustable implant system includes a bone anchor having first and second ends, a bone engagement surface adjacent the first end, and a housing extending between the first and second ends. The adjustable implant system can further include a non-invasively actuatable driving element within the housing and coupled to an adjustment component configured to couple to a flexible elongate tension member which is capable of engaging a patient's soft tissue (e.g., rotator cuff or ACL). Non-invasive actuation of the driving element can cause the adjustment component to change the amount of tension on the flexible elongate tension member and consequently on the patient's soft tissue. The adjustable implant system can include an external adjustment device configured to be placed on or adjacent the patient's skin and comprising at least one energy transferring component configured to energize/actuate the driving element inside the housing of the adjustable implant.
