Various implant fixation device embodiments have an engagement element with a concave engagement tip, a guiding element defining a planned trajectory along which the engagement element is configured to move, and an adjustment element configured to move the engagement element along the planned trajectory. Moving the engagement element along the planned trajectory causes the concave engagement tip to enter a bone in a first position and rotate within the bone to a second position. Continuing to move the engagement element along the planned trajectory may cause the concave engagement tip to undergo translational movement from the second position to a third position, thereby pulling the implant towards the bone and exerting compression forces on the bone.

When the insertion tube is removed, the woven structure expands towards its relaxed cross-sectional width to engage the endosteal wall. The woven elongated structure is impregnated with a resorbable polymer resin that cures in situ, or in the IM canal.

  • Patent number: 9421046
    Abstract: A bone transport system includes a nail having a proximal end and a distal end, the proximal end configured for securing to a first portion of bone, the distal end configured for securing to a second portion of bone. The system includes a housing having a wall with a longitudinal opening extending a length along a portion thereof. The system further includes a transport sled having a length that is shorter than the length of the longitudinal opening, the transport sled configured for securing to a third portion of bone, the transport sled further configured to be moveable along the longitudinal opening. The system further includes a magnetic assembly disposed within the nail and configured to be non-invasively actuated by a moving magnetic field, wherein actuation of the magnetic assembly moves the transport sled along the longitudinal opening. The system further includes a ribbon extending on opposing sides of the transport sled and substantially covering the longitudinal opening.

  • Patent number: 9248254
    Abstract: Described herein are devices, systems and methods for treating disease and/or infection by the release of silver from an implant over an extended period of time. In particular, the devices described herein may be used to treat infections such as osteomyelitis by the controlled release of silver ions from multiple sites of an extended-use implant. This implant typically includes a plurality of arms that both anchor and help distribute the released ions within the tissue. Power may be applied to release the silver ions into the tissue.

  • Patent number: 9198755
    Abstract: Systems and methods treat a heart valve using a magnetically adjustable annuloplasty ring attached to or near a cardiac valve annulus. A changing magnetic field may be used to selectively increase or decrease a circumference of, or otherwise modify the shape of, the implanted annuloplasty ring. The adjustable annuloplasty ring includes a tubular body member, one or more adjustable members, and an internal magnet within the tubular body member. The tubular body member and the one or more adjustable members form a ring shape. The internal magnet is configured to rotate in response to a rotating external magnetic field. The internal magnet is coupled to the one or more adjustable members to change a dimension of the ring shape as the internal magnet rotates. A system for treating a heart valve may include an external adjustment device having one or more external magnets to generate the rotating external magnetic field.

  • Patent number: 9044313
    Abstract: Disclosed herein are methods and devices for securing soft tissue to a rigid material such as bone. A tissue anchoring device is described that comprises an anchor body and a spreader such that tissue may be captured or compressed between outside surfaces on the anchor and inside surfaces of a bone tunnel to secure the tissue within the tunnel. An anchoring device is described that comprises an anchor body having compressible tabs with teeth, and a spreader that forces the compressible tabs into an expanded state when inserted into anchor body, facilitating engagement between bone and the teeth of the compressible tabs. Also described is an inserter tool that can be used to insert the anchor into bone and move the spreader within the anchor to expand the anchor and capture the tissue between the anchor and the bone. Methods are described that enable use of the bone anchoring device to secure a tissue graft into the tibial and femoral bones during anterior cruciate ligament (“ACL”) reconstruction.
