20130238095 | Nubbed Plate - A separate nub component between the plate and an intervertebral fusion cage, wherein the nub is attached to the plate. The nub lessens the undesired pivotal movement of the plate. It is believed that when the nub fits snugly between the endplates of the adjacent vertebral bodies, it acts as a stop against the undesired pivotal movement of the plate. | 09-12-2013 |
20130261673 | QUAD ANCHOR LATERAL VERTEBRAL BODY FIXATION PLATES - A bone plate secured by both a screw and a post. The head of the post may act as a cam that prevents screw backout. Preferably, the shaft of the first post passes partially through the first post through hole so that the distal unthreaded portion of its shaft substantially extends beyond the plate and the proximal threaded portion of its shaft substantially remains in the first post through hole. | 10-03-2013 |
20130345813 | Dual Anchor Lateral Vertebral Body Fixation Plates - Plate-based fixation system having dual anchors. The plate can include cams. The plates can have a banana-shape. The plates can be adapted to receive a polyaxial bone screw. The plates can be jointed so as to be height-adjustable. | 12-26-2013 |
20140058515 | SURFACE EXPANDING SPACER - An interbody spacer comprising a series of stacked walls connected by a common base, wherein the spacer collapses when pressed into an access delivery tube. During insertion, the walls can flex as a unit, like bending a deck of cards, to traverse bends in the access tube. Upon distally exiting the portal of the access delivery tube, the walls track apart (like spreading fingers) to create a wide base of support for the vertebral body endplate. A graft delivery device that uses a conveyor belt-type approach to deliver bone graft from the device to a location in a patient. In some embodiments, the conveyor-belt is manually actuated. | 02-27-2014 |
20140088990 | SYSTEMS AND METHODS FOR SURGICAL AND INTERVENTIONAL PLANNING, SUPPORT, POST-OPERATIVE FOLLOW-UP, AND, FUNCTIONAL RECOVERY TRACKING - Various systems and methods are provided for surgical and interventional planning, support, post-operative follow-up, and functional recovery tracking. In general, a patient can be tracked throughout medical treatment including through initial onset of symptoms, diagnosis, non-surgical treatment, surgical treatment, and recovery from the surgical treatment. In one embodiment, a patient and one or more medical professionals involved with treating the patient can electronically access a comprehensive treatment planning, support, and review system. The system can provide recommendations regarding diagnosis, non-surgical treatment, surgical treatment, and recovery from the surgical treatment based on data gathered from the patient and the medical professional(s). The system can manage the tracking of multiple patients, thereby allowing for data comparison between similar aspects of medical treatments and for learning over time through continual data gathering, analysis, and assimilation to decision-making algorithms. | 03-27-2014 |
20140275792 | SURGICAL RETRACTORS - The present disclosure relates to methods and devices for surgically manipulating tissue. In general, the methods and devices can include an elongate retractor shaft having a distal retractor tip that is configured to manipulate tissue, for example the tip can be configured to separate muscle and nerve fibers surrounding a vertebra. The elongate retractor shaft can include an illumination source such that at least a portion of the surgical field is illuminated by the device when the device is used in the body. A sensor can also or alternatively be included on the elongate retractor shaft, for example on the blunt retraction tip, such that the sensor can monitor physiological parameters of the tissue in or adjacent to the surgical field. | 09-18-2014 |
20140277153 | Bone Anchor Assemblies and Methods With Improved Locking - Various exemplary methods and devices are provided for fixing bone anchors to bone. In general, the methods and devices can allow for a bone anchor to be fixed to a bone at a desired angle to a receiver member. In an exemplary embodiment, a bone anchor assembly is provided that includes a bone anchor configured to engage bone, a receiver member that polyaxially seats a spherical head of the bone anchor, and a compression member seated within the receiver member, proximally of the head of the bone anchor. The compression member can have a distal end with gripping features thereon configured to create at least one line contact and/or one band contact with the head of the bone anchor, thus providing a firm grip on the head of the bone anchor and reducing a risk of slippage of the bone anchor with respect to the receiver member. | 09-18-2014 |
20140277161 | Bone Anchor Assemblies and Methods With Improved Locking - Various exemplary methods and devices are provided for fixing bone anchors to bone. In general, the methods and devices can allow for a bone anchor to be fixed to a bone at a desired angle to a receiver member. In an exemplary embodiment, a bone anchor assembly is provided that includes a bone anchor configured to engage bone, a receiver member that seats a spherical head of the bone anchor and a spinal fixation element, a compression member seated within the receiver member, proximally of the head of the bone anchor, and a closure mechanism seated within the receiver member, proximally of the compression member. One or more of the receiver member, the compression member, and the closure mechanism can have gripping features thereon configured to secure the bone anchor and/or the spinal fixation element within the receiver member, thereby reducing a risk of slippage of the bone anchor and/or the spinal fixation element with respect to the receiver member. | 09-18-2014 |
