| 20100179595 | Intervertebral Implant Devices and Methods for Insertion Thereof - Implant apparatuses are provided for being inserted between adjacent vertebral bone portions and maintaining mechanical engagement with the vertebral bone portions. The implant apparatuses are generally constructed to be inserted in an insertion orientation and pivoted between the vertebral bone portions to an implanted orientation. The implant apparatuses are further secured in the implanted orientation to maintain engagement with the adjacent vertebral bone portions. | 07-15-2010 |
| 20100042216 | Implant for Deploying Bone Graft Material and Methods Thereof - Invertebral implants are provided for carrying bone graft material and extruding the bone graft material between the implant and the adjacent vertebral bodies. The implants include first and second implant extrusion members shiftable relative to one another between a pre-implantation configuration having an enlarged cavity for receiving bone graft material therein and an implantation configuration having a smaller cavity. As the first and second implant extrusion members shift during implantation to the implantation configuration bone graft material is extruded from the cavity and into gaps or spaces between the upper and lower vertebral engaging surfaces of the implant and the adjacent vertebral bodies. After extrusion the bone graft material is subjected to spinal loading and stress to encourage strong bone growth therethrough. | 02-18-2010 |
| 20090270927 | Bone Plate System - A bone plate system is provided that includes bone plates and bone anchor assemblies for being inserted into bone plate bores to secure the bone plates to one or more bones. In one aspect, the bone plate system includes a bone anchor assembly having a locking cap and a locking fastener connected to a head portion of a bone anchor. The bone anchor assembly is driven into a bone plate bore before the locking fastener is shifted to expand the locking cap and fix the bone anchor assembly within the bore. In another aspect, the bone plate system includes a bone anchor assembly having a locking cap that deflects radially inward due to contact with the bone plate at large bone anchor assembly insertion angles. In addition, a bone anchor assembly having a preassembled condition with a locking cap resisting back out of a locking fastener. | 10-29-2009 |
| 20090221153 | Electrical Connector for Surgical Systems - An apparatus for creating an electrical connection with a surgical tool is provided that is capable of engaging the shafts of rotatable surgical tools having varying diameters. In one aspect, the apparatus includes a body of nonconductive material connected to a pair of spaced, electrical contact members that provide two spaced points of contact with the tool shaft. In another aspect, a contact arm is provided which pivots within a slot formed within a housing to receive larger diameter tool shafts. Additionally, the contact arm closes an opening on the housing and resiliently shifts to an open position as the contact arm is brought into engagement with the tool shaft. A method of connecting a conductor assembly to a rotatable tool shaft is also provided which includes using tension in the conductor assembly to resist rotation of a gripping end of the assembly connected to a rotatable tool. | 09-03-2009 |
| 20090069635 | Retraction Apparatus And Method Of Use - A retraction apparatus and method are disclosed that provide optimized access to a surgical site. In one form, a retraction frame has a retraction opening with two sets of blades operating therein. The blades are used to sequentially retract the tissue from about an incision. The sequential retraction of the blades generates only narrow gaps between the blades so that tissue and blood encroachment during the surgical procedure are minimized. | 03-12-2009 |
| 20090062862 | Bone Plate System - Bone plate systems for surgical implants and bone repair are provided. The bone plate is multi-tiered for receiving bone anchors for securing a plurality of bones or bone fragments in a desired relationship. The plate members include throughbores for receiving a pivot base therein, with head ends of the bone anchors being secured within the pivot bases. The throughbores may permit and define a translation path for the pivot base and the bone anchor secured therein relative to the plate. The configuration of the pivot base and the throughbore facilitate pivoting and optional translation of the pivot base relative to the plate. With the bone anchor seated within the pivot base, an apparatus for inhibiting bone anchor back out is employed. | 03-05-2009 |
| 20090012571 | Bone Plate System - Bone plate systems are provided for surgical implants and bone repair. The bone plate is multi-tiered for receiving bone anchors screws for securing a plurality of bones or bone fragments in a desired relationship. The plate members include throughbores for receiving a pivot base therein, with head ends of the bone anchors being secured in the pivot bases. The throughbores may permit and define a translation path for the pivot base and the bone anchor secured therein relative to the plate. Pivot members extending between the pivot base and the plate member facilitate pivoting and optional translation of the pivot base relative to the plate. With the bone anchor seated within the pivot base, an apparatus for inhibiting screw back out is employed. | 01-08-2009 |
| 20080312654 | Method for Marking Orthopedic Implant - A novel process for marking implants and instruments is provided by masking a portion of the implant or instrument and then applying a treatment to alter the appearance of the unmasked area. The process may be used to mark surfaces not suitable for laser or chemical etching. | 12-18-2008 |
