  • Patent number: 10675064
    Abstract: One or more techniques and/or systems are disclosed for a system for distraction osteogenesis of long bones. Selectively adjustable drive magnets disposed in the system can be used to distract the device. An external drive device generating a magnetic field may be used to rotate the drive in externally.
    Type: Grant
    Filed: November 9, 2017
    Date of Patent: June 9, 2020

  • Patent number: 10016226
    Abstract: One or more techniques and/or systems are disclosed for a system for noninvasive adjusting fastener tensioning has an elongated shaft having a slot defined therein. The shaft has a first end oppositely disposed from the second end. An associated rod or rods may pass through each end. Selectively adjustable fasteners may have a plurality of magnets disposed in the head of the fastener. An external drive device generating a magnetic field may be used to rotate the fasteners via the magnets in the fastener head externally without the need for surgery. The fasteners may move in and out from the shaft and contact the rod to adjust tensioning.

  • Patent number: 9339370
    Abstract: An apparatus for anchoring elongate strands within a longitudinal tunnel is disclosed. At least two cams are arranged longitudinally adjacent each other along a longitudinal axis. A first anchor member includes a first cam-contacting surface and a first strand-contacting surface. The first cam-contacting surface is selectively operatively connected to a first cam. A second anchor member includes a second cam-contacting surface and a second strand-contacting surface. The second cam-contacting surface is selectively operatively connected to a second cam. An elongate strand is positioned between the tunnel wall and the first or second strand-contacting surfaces.

  • Patent number: 9011536
    Abstract: An apparatus for anchoring at least two graft ligaments within a longitudinal bone tunnel includes a longitudinal sleeve having at least two ligament-contacting surfaces located in lateral opposition to a sleeve inner lumen. The sleeve is configured for at least partial insertion into the bone tunnel with each graft ligament positioned laterally adjacent a different ligament-contacting surface and at least partially located between the bone tunnel and the sleeve. An actuating member has proximal and distal actuating member ends. An asymmetrically offset profile is defined by the sleeve and/or the actuating member. The asymmetrically offset profile has engagement thresholds. The actuating member is inserted into the sleeve to cause frictional engagement of each graft ligament with both the bone tunnel and at least one ligament-contacting surface, the frictional engagement of each graft ligament being temporally spaced apart from the frictional engagement of at least one other graft ligament.

  • Patent number: 8491652
    Abstract: An apparatus for anchoring at least two graft ligaments within a longitudinal bone tunnel includes a longitudinal sleeve having at least two radially spaced ligament-contacting surfaces located in lateral opposition to a sleeve inner lumen. The sleeve is configured for at least partial insertion into the bone tunnel with each graft ligament positioned laterally adjacent a different ligament-contacting surface. The graft ligaments are at least partially located between the bone tunnel and the sleeve. An actuating member has longitudinally separated proximal and distal actuating member ends. An asymmetrically offset profile is defined by at least one of the sleeve and the actuating member. The asymmetrically offset profile has a plurality of longitudinally spaced engagement thresholds. The actuating member is inserted longitudinally into the sleeve to cause frictional engagement of each graft ligament with both the bone tunnel and at least one ligament-contacting surface.
