A woven retention device for interfacing with a bone surface is provided that includes a sleeve body that can surround a fastener, a proximal end for receiving the fastener, and a distal end. The sleeve body includes interwoven monofilaments of different diameters forming a substantially tubular lattice with protuberances distributed on interior and exterior surfaces of the lattice at a predetermined spatial relationship. In a first state, the sleeve body has a plurality of combinations of filament cross-section geometries at the intersection points, forming a plurality of protuberance thicknesses as measured in a radial direction of the sleeve body. In a second state when a fastener is inserted into the tubular lattice, pressure from the fastener is transmitted to the tubular lattice such that the spatial relationship of the protuberances changes according to a function of bone density and an interfacing surface shape of the fastener.

Woven retention devices, systems and methods

A kit for implanting a woven retention device into bone includes a woven retention device, a delivery tube, and a push rod. The woven retention device includes a distal end that is tapered to a distal tip, a proximal end for receiving a fastener, and a sleeve body between the distal and proximal ends. The delivery tube includes distal and proximal openings, and a compression portion over at least a distal end of the delivery tube. The push rod can be slideably received within the delivery tube and has a distal end for pushing the woven retention device through the distal opening of the delivery tube.

Woven retention devices, systems, packaging, and related methods

A woven retention device for interfacing with a bone surface includes interwoven filaments forming a tubular lattice with protuberances distributed on interior and exterior surfaces of the lattice at a predetermined spatial relationship. The protuberances are formed by intersecting interwoven filaments. The retention device receives and surrounds a fastener. In a first, relaxed state, the retention device has multiple combinations of filament cross-section geometries at the intersection points, and the multiple combinations of filament cross-section geometries form multiple protuberance thicknesses. In a second state when surrounding at least a portion of the fastener, the retention device distributes pressure from the fastener to multiple points of contact on the exterior surface of the retention device such that a spatial relationship of the protuberances changes as a function of bone density of the bone surface and as a function of an interfacing surface shape of the fastener.

The present invention teaches an improved spinal fusion implant and method of implanting same. The implant includes a shell and an insert, the insert capable of situating first and second plates of the shell with respect to each other and of preventing unwanted loosening of fasteners placed through the shell and into the adjacent vertebral bodies. The method includes implanting a shell, selecting an insert from a plurality of inserts, and placing an insert between first and second plates of the shell.

A spinal plating system for vertebral fixation includes a plate, a compression screw, multiple fixation members and polyaxially adjustable locking rings. The plate is shaped to conform to the curvature of the spine and the surfaces of the vertebral bodies. The compression screw fits through an insert, and together they are guided by the plate as the screw is driven into one of the vertebrae, producing compression between the adjacent vertebrae. A retaining lip on the plate prevents backout of the compression screw. The polyaxial locking rings can be polyaxially pivoted to attain a desired orientation, and are lockable to the plate to maintain the orientation. The fixation members fit through openings in the polyaxial locking rings and the plate to fix the plate to the vertebrae. Locking the polyaxial locking rings fixes the position of the fixation members relative to the plate, and prevents backout of the fixation members.

System and method for vertebral body plating

A method of dilating an incision to provide access to a surgical site. Such method may include the steps of making an incision in the skin of a patient near a predetermined surgical site, inserting into the incision a dilator, inserting at least one shoe horn in juxtaposition or in direct apposition with the dilator, removing the dilator from the incision, inserting a blunt dissector adjacent the at least one shoe horn, removing the at least one shoe horn, inserting a retractor or a tube over the blunt dissector and into the incision such that the retractor or tube is at or adjacent the predetermined surgical site, removing the blunt dissector from the incision, and performing a surgical procedure at the predetermined surgical site through the retractor or tube.

Switching stick dilation method and apparatus

A system and method for the stabilization of the human spine using rods or plates having variable shapes and mechanical properties over their length. The rods or plates may be made up of various segments, each having different properties such as different flexibilities.

Methods and apparatus for modular and variable spinal fixation

A spinal implant insertion guide is disclosed. The insertion guide includes at least one channel suitable for receiving and facilitating movement of a spinal implant into an intervertebral space between two vertebrae and a portion suitable for insertion into the intervertebral space. In embodiments for use with spinal implant having multiple pieces, the pieces of the spinal implant remain in cooperation throughout movement. The guide may further include a plunger for facilitating the movement of the spinal implant.

Insertion guide for a spinal implant

A bone fusion implant system including a first implant body having substantially flat top and bottom surfaces for engaging opposing vertebrae and a side wall extending between the top and bottom surfaces, the side wall including a concave recess and a second implant body having substantially flat top and bottom surfaces for engaging the opposing vertebrae and a side wall extending between the top and bottom surfaces thereof, the side wall of the second implant including an arcuate portion adapted to be received within the concave recess for enabling the first and second implant bodies to be positioned in nested side-by-side relation between the opposing vertebrae.
