    摘要: A system for restoring articular cartilage has a cover, an anchor, and a tether that cooperate to retain graft tissue with respect to a graft site. The cover is attached to the anchor via the tether. The tether passes through a tunnel through a bone to which the articular cartilage is attached. The tunnel connects the graft site to an anchoring side of the bone. The anchor is retained proximate the anchoring side such that tension in the tether keeps the cover in place over the tissue graft to capture the tissue graft at the proper position with respect to the graft site. The cover and/or the anchor may be bioabsorbable. The cover may be perforated to permit fluids to access the tissue graft from outside the cover to enhance incorporation of the graft tissue with the graft site. The cover may be formed of rigid or flexible materials.

    摘要: A line lock includes a body at least partially bounding a plurality of passageways such that a suture can only be drawn through the passageways along one direction. The suture is attached to the line lock prior to use in surgery, either by securing one end of the suture to the line lock, or by retaining a loop of the suture with one of the passageways. A needle may be pre-attached to a free end of the suture. The suture may be inserted through the passageways through the use of a cartridge designed to contain the line lock. A threader may pass through the line lock within the cartridge along the desired pathway for the suture. Thus, the suture may be coupled to the threader and drawn through the passageways along the desired pathway by pulling the threader from the cartridge.

    摘要: A posterior spinal fusion system may include pedicle screws and one or more segments designed to be attached to the implanted pedicle screws via nuts to fuse spinal motion segments in a modular fashion. The pedicle screws may have semispherical receiving surfaces, and each segment may have mounting portions at both ends, with corresponding semispherical engagement surfaces. The nuts may also have semispherical surfaces. The semispherical surfaces permit polyaxial adjustment of the relative orientations of the segments and pedicle screws. Each mounting portion may have a passageway therethrough to receive the proximal end of the corresponding pedicle screw; each passageway may intersect the edge of the corresponding engagement surface to facilitate percutaneous placement. Such placement may be carried out through cannulae to provide a minimally invasive (MIS) implantation procedure.

    摘要: A dilating system for dilating bodily tissue includes a elongate tubular first dilator and a elongate tubular second dilator. The second dilator has an outer diameter greater than the outer diameter of the first dilator, the first dilator being configured to be received within the second dilator. In one embodiment, a first mating member is formed on the exterior surface of the first dilator while a second mating member is formed on the interior surface of the second dilator. The first mating member engages with the second mating member when the second dilator is passed over the first dilator so as to cause the second dilator to travel along a fixed path relative to the first dilator.

    摘要: A line lock includes a body at least partially bounding a plurality of passageways such that a suture can only be drawn through the passageways along one direction. The suture may be inserted through the passageways through the use of a cartridge designed to contain the line lock. Threaders may pass through the line lock within the cartridge. Each threader may have a leading end and a trailing end that can be coupled to a suture end. Thus, two suture ends may be drawn through the passageways by coupling them to the threaders and drawing the leading ends of the threaders to cause the suture ends to pass through the passageways according to the desired pattern. The cartridge may then be opened to permit easy removal of the suture and the line lock.

    摘要: A line lock includes a body at least partially bounding two passageways that cooperate to receive a locking portion of a line such as a suture in such a manner that the locking portion can only be drawn through the passageways along one direction. A second suture locking portion may also received by the passageways, or by one of the two passageways in combination with a third passageway. The body may have an elongated, compact shape that is easily implantable in the body.

    摘要: A mill guide instrument for guiding a tissue cutting tool is provided that is made up of subassemblies of a guide body and a mill guide. The guide body has a distal section dimensioned to fit into a bore in bone and a removable template with a guide surface unique to a proposed cavity shape. The mill guide is connected to the guide body and provides for controlled relative motion between the mill and the guide body. The mill guide has an attached stylus that follows the guide surface of the template. The stylus follows the template guide surface so as to constrain the path of the mill to a preferred milling path.
