    摘要: An instrument for inserting an elongated hydrogel prosthesis into an intervertebral disc includes an insertion cannula that is inserted through the annulus fibrosus of an intervertebral disc to provide access to the nucleus region of the disc, an elongated hydrogel prosthesis packaged within a tubular container adapted to be coupled to a proximal end of the insertion cannula, and a source of fluid pressure adapted to be coupled to a proximal end of the tubular container. Auxiliary instruments for use in convenient insertion of the insertion cannula through the nucleus pulposus and providing for a complete and controlled passage of the hydrogel prosthesis through the insertion cannula are provided in a kit with the insertion cannula. A sizing apparatus for determining the volume of prosthesis to be inserted includes a catheter or cannula capable of being inserted through the insertion cannula into the nucleus region of the intervertebral disc and having at its distal end a balloon capable of being inflated within the intervertebral disc with a measurable volume of a fluid in order to determine the amount of hydrogel prosthesis to be injected.

    摘要: A flexible implant system for positioning a flexible spacer between adjacent vertebrae including and interbody spacer and an insertion instrument. The interbody spacer including a central axis, a lateral axis, a top surface positioned generally parallel to the central axis and a plurality of hinge sections extending generally perpendicular to the central axis. A plurality of notches making up the plurality of hinge sections adjacent the top surface that permit the interbody spacer to flex. The interbody spacer further including a groove extending along a lateral side surface, generally parallel to the central axis. An insertion instrument includes a proximal end, a distal end and a tongue extending from the proximal end to the distal end along a non-linear path. The groove slidably engages the tongue to guide the interbody spacer from the proximal end to the distal end along the non-linear path.

    摘要: In one aspect of the invention, a cross-pin includes a distal portion having an axis, a distal end, and a proximal end. A proximal cylindrical portion includes a threaded exterior surface. A junction may be interposed between the distal and proximal portions to enable the proximal portion to rotate relative to the distal portion. In another aspect of the invention, a graft retaining system for retaining a graft in a bone tunnel includes a graft block having a proximal end and a distal end, and sized to fit within the bone tunnel. A cross pin transverse to the bone tunnel attaches the graft block adjacent the tunnel. An intermediate connector is attached to the graft block at a point distal to the cross pin and connects the graft to the graft block so as to apply compressive forces to the graft block.
