Patent application number | Description | Published |
20080243186 | Spinal stabilization systems and methods of use - Devices and methods are adapted to permit fixation and stabilization of the bony elements of the skeleton. The devices permit adjustment and maintenance of the spatial relationship between neighboring bones. The motion between adjacent skeletal segments may be maintained, limited or completely eliminated. | 10-02-2008 |
20090177238 | DISTRACTION SCREW FOR SKELETAL SURGERY AND METHOD OF USE - An improved distraction bone screw and a method for its use are described. The distraction screw is comprised of an implantable distal segment and a detachably secured proximal segment. The distal segment includes a head portion and a threaded shank portion. The proximal segment is represented as an elongated body having an internal bore that extends through its length. A deployable member is disposed within the bore, which is extendible outside the internal bore to securely couple to the distal segment. | 07-09-2009 |
20100016906 | DEVICE AND METHOD TO ACCESS THE ANTERIOR COLUMN OF THE SPINE - Devices and methods for delivery of inter-vertebral implants that do not require extensive dissection of normal tissues or significant retraction of the nerve elements are disclosed. The devices and methods provide ease of use as well as a safe and familiar surgical approach that maximizes the likelihood of optimal device placement within the inter-vertebral space. | 01-21-2010 |
20100069965 | DEVICE AND METHOD FOR THE PREVENTION OF MULTI-LEVEL VERTEBRAL EXTENSION - Methods and devices are adapted to limit the extent of vertebral extension between an upper-most vertebral bone and a lower-most vertebral bone wherein a least one additional vertebral bone resides between them. In an embodiment, the limitation of extension occurs while flexion is at least partially maintained within at least one FSU. In other embodiments, flexion may be abolished. | 03-18-2010 |
20100076448 | PLATING SYSTEM FOR BONE FIXATION AND METHOD OF IMPLANTATION - A modular bone distraction screw and a plate-based bone fixation device are well adapted for use in the spine. A plate has adjustable length and can accommodate bone settling. The method of use for each device is described and illustrated herein. | 03-25-2010 |
20100087858 | DYNAMIC CONNECTOR FOR SPINAL STABILIZATION AND METHOD OF USE - Disclosed are novel dynamic rod systems and methods that provide robust fixation and a reliable resistor to motion. A first end of a movable orthopedic implant is attached onto a first vertebral bone of a functional spinal unit and a second end onto a second vertebral bone of a functional spinal unit. The implant has a longitudinal axis and permits movement of the attached vertebral bones along that longitudinal axis. The device may contain a member that is adapted to resist movement wherein longitudinal movement of a first device member relative to a second device member produces rotational movement about the long axis the device within the resisting member. | 04-08-2010 |
20100087869 | DEVICES AND METHODS TO LIMIT ABERRANT MOVEMENT OF THE VERTEBRAL BONES - Methods and devices are configured to attach an orthopedic implant onto a first vertebral bone of a functional spinal unit. A segment of the implant forms an abutment surface with a segment of a second vertebral bone within an unstable, or potentially unstable, vertebral column wherein the abutment surface resists and opposes aberrant movement between the first and second vertebral bones within a horizontal plane. The device may be rigidly attached onto the first vertebral bone but movable relative to the second vertebral bone. | 04-08-2010 |
20100087878 | DEVICE AND METHOD TO ACCESS THE ANTERIOR COLUMN OF THE SPINE - Methods and devices are configured to permit a surgeon to access the anterior column of the spine without significant manipulation of intervening nerve elements. | 04-08-2010 |
20100087923 | IMPLANTS FOR FACET JOINT REPAIR AND METHODS USE - An orthopedic implant is positioned within the facet joint and is attached to the posterior surface of the SAP (superior articular process) of the inferior vertebral bone or onto the anterior surface of the IAP (inferior articular process) of the superior vertebral bone. The implant increases the distance between the IAP and SAP surfaces that make up a facet joint and reduce the joint laxity and at least partially correct the spondylolisthesis produced by a degenerative process. | 04-08-2010 |
20100106250 | BONE FIXATION AND FUSION DEVICE - Disclosed is a bone fusion cage that contains bone graft and is implanted between bones in a skeletal system. The cage bears structural loads that are transmitted through the bones of the skeletal system and at least partially shields the contained bone graft from the structural loads. The cage is configured to provide a secondary load to the bone graft independent of the structural load to promote fusion of the bone graft to adjacent bones. | 04-29-2010 |
20100121384 | OCCIPITAL FIXATION SYSTEM AND METHOD OF USE - Disclosed is a multi-axial occipito-cervical connection system that enables an occipital rod to be coupled to a cervical rod in a manner that permits multi-axial, relative movement between the two rods about a predetermined location, such as the heads of the rods. The system includes a locking mechanism that can be actuated to lock the relative positions of the rods. The rods can provide an interconnection between one or more attachments on the skull (such as an occipital attachment) and one or more attachments to the spine (such as spine screws). | 05-13-2010 |
20100211177 | DEVICES AND METHODS FOR INTER-VERTEBRAL ORTHOPEDIC DEVICE PLACEMENT - Disclosed are methods and devices for implanting an orthopedic device between skeletal segments, such as vertebrae, using limited surgical dissection. The implanted devices are used to adjust and maintain the spatial relationships of adjacent bones. The implanted device can be, for example, an artificial disc, a fusion cage or any other appropriate device for implantation between skeletal segments. | 08-19-2010 |
20100268281 | DEVICES AND METHODS FOR INTER-VERTEBRAL ORTHOPEDIC DEVICE PLACEMENT - Within a given spinal segment, the stable vertebral level is identified. Within the lower lumbar spine, that level is most commonly at the sacrum. A bone fastener is rigidly affixed to the stable spinal segment and an interconnecting member is rigidly affixed to the bone fastener so as to form a cantilever construct. Vertebral bodies that exhibit aberrant spinal motion and/or mal-alignment relative to the stable segment are then attached to the interconnecting member using non-rigid bone fastener(s). The motion profile of the dynamic fastener can be varied and may be selected to provide the desired vertebral motion characteristics. The interconnecting member may be rigid or it may be alternatively made rigid parallel to the direction of greatest instability and non-rigid in the other planes. | 10-21-2010 |
20120109206 | OCCIPITAL FIXATION SYSTEM AND METHOD OF USE - Disclosed is a multi-axial occipito-cervical connection system that enables an occipital rod to be coupled to a cervical rod in a manner that permits multi-axial, relative movement between the two rods about a predetermined location, such as the heads of the rods. The system includes a locking mechanism that can be actuated to lock the relative positions of the rods. The rods can provide an interconnection between one or more attachments on the skull (such as an occipital attachment) and one or more attachments to the spine (such as spine screws). | 05-03-2012 |
20120310282 | DEVICE AND METHOD FOR THE PREVENTION OF MULTI-LEVEL VERTEBRAL EXTENSION - Methods and devices are adapted to limit the extent of vertebral extension between an upper-most vertebral bone and a lower-most vertebral bone wherein a least one additional vertebral bone resides between them. In an embodiment, the limitation of extension occurs while flexion is at least partially maintained within at least one FSU. In other embodiments, flexion may be abolished. | 12-06-2012 |
