Appl. No.:

11/854132

Inventors:

Robert J. Delurio - Aston PA, US
Ryan Walsh - Douglassville PA, US
Joshua McManus - Downingtown PA, US

Assignee:

Synthes USA, LLC - West Chester PA

International Classification:

A61F 2/44

US Classification:

623 1715, 623 1711, 623 1716

Abstract:

The present invention is directed to an allograft intervertebral implant sized and configured for insertion between adjacent vertebral bodies in a spinal fusion surgery. The implant is preferably manufactured from two or more pieces of allograft bone joined together by a joint, more preferably a dovetail joint. The dovetail joint being sized and configured to substantially follow the exterior shape or surface (e. g. perimeter) of the intervertebral implant. The intervertebral implant may also include one or more bone pins for joining the allograft pieces, the pins being inserted into the implant at an angle substantially perpendicular with respect to the dovetail joint. The intervertebral implant may also include one or more through-bores for receiving ostegenic or bone graft material. The intervertebral implant is preferably sized and configured for insertion during a T-PLIF or PLIF procedure.

International Classification:

A61B 17/70

US Classification:

606249

Abstract:

An interspinous process spacer is generally rectangular and may have an upper face that generally opposes a lower face, front and back sides that generally oppose each other, an end side, and a nose that generally opposes the end side. The spacer preferably has rounded edges between the upper face and the front, end, and back sides and between the lower face and the front, end, and back sides. The nose of the spacer is preferably asymmetrical and tapers integrally, distally, and inwardly from the first and second faces to form a generally pointed or rounded distal tip. A spacer may be inserted laterally into the interspinous space through a small, posterior midline incision, allowing the preservation of the supraspinous ligament. One or more spacers may be placed between spinous processes of adjacent vertebrae, and result in distraction of the spinous processes which may limit extension of the spine.

US Classification:

623017110, 623911000, 606099000

Abstract:

An allogenic implant for use in intervertebral fusion is formed from one or more two pieces. The pieces are made from bone, and are joined together to form an implant having sufficient strength and stability to maintain a desired distance between first and second vertebrae in a spinal fusion procedure. The implant pieces may be formed of cortical bone and connected by dovetail joints, and at least one cortical bone pin may be provided to lock the pieces together and to add strength to the implant. Teeth are formed on the vertebra engaging surfaces of the implant prevent short-term slippage of the implant.

International Classification:

A61F 2/44

US Classification:

623 1716, 623 1711

Abstract:

A flexible chain implant for insertion into an interior volume of a vertebral body. The implant may be implanted in an insertion position for sliding through a cannula and is flexible for packing into the interior volume in an implanted configuration. The implant randomly separates in the implanted configuration. The implant includes a top member and a bottom member, wherein the top and bottom members are coupled to one another at a coupled portion. The top and bottom members preferably each include an inner surface such that the inner surfaces include a plurality of alternating projections and recesses so that the projections are received within the recesses in an insertion position. Alternatively, the implant may include a plurality of substantially non-flexible bodies and a plurality of substantially flexible links interconnecting the bodies. The non-flexible bodies include a plurality of facets and/or abutment surfaces.

US Classification:

623 2363, 606300, 156155, 156 93

Abstract:

The present invention provides a system, device, instruments and methods for inserting and/or improving the holding strength and purchase of a bone screw, bone pin, or bone dowel in bone. Embodiments include monolithic allograft tissue forms, multi-piece allograft tissue forms, distally expandable portions, partially and fully demineralized portions, and flexible connecting portions. Advantages of the allograft tissue forms of the present invention include improved pedicle screw blackout strength and improved filling of bone voids. Methods for making and instruments and techniques for inserting the augmentation device, system and screws or pins are also disclosed.

US Classification:

606249, 606279

Abstract:

An allograft interspinous spacer for implantation into an interspinous space located between spinous process of adjacent vertebrae. The spacer preferably includes a body, a core and a plurality of deployable retainers. The body may be operatively associated with the plurality of deployable retainers. In use, after the body has been inserted into the interspinous space, the plurality of retainers is deployed so that they prevent migration of the spacer. The core is preferably sized and configured to be inserted and/or moved into operatively engagement with the body to deploy the plurality of retainers.
