Abstract: A system includes a first pedicle screw, a second pedicle screw, and an adjustable rod having an outer housing coupled to one of the first pedicle screw and the second pedicle screw, the outer housing having a threaded shaft secured to one end thereof extending along an interior portion thereof. The system further includes a hollow magnetic assembly disposed within the outer housing and having a magnetic element disposed therein, the hollow magnetic assembly having an internal threaded surface engaged with the threaded shaft, the magnetic assembly being coupled to the other of the first pedicle screw and the second pedicle screw, wherein the hollow magnetic assembly rotates in response to an externally applied magnetic field to thereby lengthen or shorten the distance between the first pedicle screw and the second pedicle screw.

Abstract: A system for accessing a surgical target site and related methods, involving an initial distraction system for creating an initial distraction corridor, and an assembly capable of distracting from the initial distraction corridor to a secondary distraction corridor and thereafter sequentially receiving a plurality of retractor blades for retracting from the secondary distraction corridor to thereby create an operative corridor to the surgical target site, both of which may be equipped with one or more electrodes for use in detecting the existence of (and optionally the distance and/or direction to) neural structures before, during, and after the establishment of an operative corridor to a surgical target site.

Abstract: A system for non-invasively adjusting the curvature of a spine includes a housing having a first end and a second end, a first rod having a first end telescopically disposed within a cavity of the housing along a first longitudinal axis at the first end of the housing and having a first threaded portion extending thereon, and a second end configured to be coupled to a first portion of a spinal system of a subject, a second rod having a first end telescopically disposed within the cavity along a second longitudinal axis at the second end of the housing and having a second threaded portion extending thereon, and a second end configured to be coupled to a second portion of the spinal system of the subject, a driving member rotatably disposed within the cavity and configured to be activated from a location external to the body of the subject.

Abstract: A surgical retractor assembly is provided having a frame that releasably couples two retractor blades. The retractor blades are coupled to the frame via a pair of mobile carriages that engage a track on the frame. A third retractor blade is configured to be independent of the frame with the first two retractor blades. The independent blade may be fixably positionable in the patient by a direct coupling to a rigid table mount. The retractor assembly may be utilized for creating anterior access to spinal target site while the patient is oriented in the lateral decubitus position.

The filter device is dimensioned for use with a container having a mixture of bone graft material including demineralized bone matrix particles and liquid, whereby the filter device is placed in the container, the liquid is poured off through the pores in the filter device, and the demineralized bone matrix particles are retained with bone graft material in the container.

Abstract: 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.
