摘要： A radially compressed xerogel spinal nucleus implant is manufactured and utilized for implantation into an intervertebral disc space. The implant has an optimized cross-sectional ellipsoid configuration which facilitates insertion of the implant through a minimal incision in the annulus. Radial compression is achieved by exerting substantially equilateral circumferential compression on an object contained within a radially collapsible member for exerting substantially equilateral circumferential compression on the object. Radial compression may also be achieved by exerting substantially equilateral circumferential compression force on a spinal nucleus implant via gas pressure in a sealed chamber.

The polymeric matrix may be a fluid absorbing polymer, e.g., a hydrogel or a substantially non-fluid absorbing in-situ curable elastic polymer. A method of making a spinal nucleus implant is provided which includes providing a braided three-dimensional reinforcement member configured and dimensioned to have a shape consistent with a cavity in an intervertebral space and infusing the braided three-dimensional reinforcement member with a liquid polymer capable of forming a polymeric matrix. Also provided is a spinal nucleus implant including a three-dimensional reinforcement member adapted and configured to undergo anisotropic expansion, the implant configured to have a shape consistent with a cavity within an intervertebral disc space. A method of treating a degenerating intervertebral disc includes creating an incision in an annulus; removing at least a portion of a nucleus pulposus; and inserting, through the incision, a spinal nucleus implant according to the present disclosure.

In one embodiment, the support member is fabric selected from the group consisting of mesh, woven fabric and nonwoven fabric. In one embodiment, the support member includes at least one portion which is located outside of the body, said portion adapted to engage one or more guides for orienting the implant. In one embodiment, the implant is capable of expanding from a compact, substantially dehydrated configuration to an expanded hydrated configuration. A method of manufacturing a spinal nucleus implant is provided which includes coagulating a liquid polymer such that at least a portion of said support member extends beyond the perimeter of the polymer to form a spinal nucleus implant having an interiorly disposed support member which extends out of the polymer. A method of implanting such a spinal nucleus implant is provided.

摘要： There is disclosed a manipulation and storage tool for receiving and manipulating a partially dehydrated intervertebral disk. Manipulation and storage tool is configured to receive the disk and manipulate it into a smaller overall size and subsequently insert it into a temporary storage or sleeve device for later use. Manipulation and storage tool generally includes a manipulation assembly which is movably mounted with respect to a guide assembly. The guide assembly includes a throughbore and a slot for receiving the disk into the throughbore as well as a sleeve holder mounted at a distal end designed to retain a storage device or sleeve into which the manipulated disk is inserted. The manipulation assembly generally includes a drive member having an elongated shaft movably mounted within the bore of the guide assembly and at least one manipulation member for pin positioned adjacent the slot to manipulate the implant in response to movement of the drive member relative to the guide assembly. Preferably, the drive member and guide assembly are inter-connected by a drive rod having a chive pin which guides the motion of drive member with respect to the guide assembly in response to rotation of the drive member to manipulate the disk and insert it into the sleeve. There is also disclosed an insertion tool for receiving an assembled sleeve and disk and inserting the manipulated disk into an intervertebral disk space. Methods of use of the manipulation and storage tool and the inserter tool are also disclosed. There is also disclosed an implant folding and storage device including an implant folding device having a pair of jaws configured to fold an implant therebetween. An implant transfer device is provided to move the folded implant from within the implant folding device and into an implantation tube. There is also disclosed a novel surgical instrument assembly for receipt of a folded implant and installation of the implant into a portion of the body.
