20100191287 | Flexible and Static Interspinous/Inter-Laminar Spinal Spacers - Interspinous/inter-laminar spinal spacers (spinal spacers) are configured to be placed between bony structures (i.e. transverse and spinous processes) of adjacent vertebrae of a spine. In one form, flexible spinal spacers are defined by a unitary body that is configured to be placed between bony structures of adjacent vertebrae of a spine. The unitary body has a flex portion that provides for motion between the adjacent vertebrae to which it is coupled. The flex portion is configurable to provide for various degrees of angulation, flexion, extension and/or compression of the present flexible spinal spacer. In another form, static spinal spacers are defined by a unitary body that is configured to be placed between bony structures of adjacent vertebrae of a spine. The unitary body has saddle-shaped ends each defining a pocket that is configured to receive a bony structure of a vertebra. The pockets may or may not be textured and/or may or may not include teeth, serrations or ridged surfaces to secure the spinal spacer to the bony structure. | 07-29-2010 |
20110015745 | Combined Spinal Interbody and Plate Assemblies - A spinal implant assembly combines a spinal interbody spacer with a spine plate. The combined spinal interbody spacer and spine plate assembly provides stabilization and torsional resistance to promote fusion of adjacent vertebrae of the spine. The interbody spacer is configured for placement within an intervertebral space between the adjacent vertebrae previously occupied by a spinal disc. The spinal plate is configured for attachment to anterior sides of the adjacent vertebrae (either on or within the vertebrae). The spinal plate may translate relative to the interbody spacer or it may be fixed relative to the interbody spacer. Translation of the spinal plate allows it to be affixed to the vertebrae in various positions and/or allow movement post installation. In one form, the spinal plate is defined by first and second spine plate or plate portions that are coupled to one another to allow rotation about each other. Ends of the first and second spine plates are received in/by the interbody spacer, while a pin extends through the interbody spacer to fix the first and second spine plates to the interbody spacer. In another form, the spinal plate is defined by first and second spine plates or plate portions that are movably retained by the interbody spacer. In call cases, the first and second spine plates each have one, two or more screw holes for accepting a bone screw for fixing the spine plates to the adjacent vertebrae. | 01-20-2011 |
20110029021 | Spinous Process Spacer - A spinous process spacer that is designed to maintain a desired spatial relationship between adjacent vertebrae, is configured for introduction into a spinal implant site in a compressed state and then expands in situ. Once expanded, formations of the present spinal spacer form areas, pockets or spaces that receive at least one bony portion of each adjacent vertebra. The present spinous process spacer has a changeable circumferential profile wherein a first circumferential profile is smaller than a second circumferential profile in order to provide/achieve its compressed and expanded states. The first circumferential profile defines the collapsed position or state while the second circumferential profile defines the position or state. Upon implantation, the present spinous process spacer is not fixed to any bony structure of the vertebrae but provides support. In this regard, use of the spinous process spacer, by itself, will not result in vertebral fusion. However, fusion can result with the use of bone graft packed about the spinous processes (and the spinous process spacer) or in conjunction with the use of an intervertebral body spacer. | 02-03-2011 |
20110106168 | Laminoplasty Rod System - A laminoplasty rod and rod system that allows for variable angulation, translation (distraction and/or compression) and rotation of a spinal lamina bone portion associated with a laminoplasty, prior to fixation thereof. The laminoplasty rod is configured for use with a polyaxial spinal rod bone screw assembly that is adapted to be anchored to the vertebra associated with the laminoplasty, and is attachable to the spinal lamina bone portion. The laminoplasty rod system provides positional attachment of the laminoplasty rod to the spinal components associated with the laminoplasty and fixation thereof in various orientations. The laminoplasty rod system is characterized by a configured laminoplasty rod that fits into or onto the head of a polyaxial spinal rod bone screw assembly. A bone screw boss, defining a bone screw attachment configuration, is formed at one end of the laminoplasty rod. Preferably, but not necessarily, the bone screw boss is situated at an angled end of the rod having a pre-defined bend that provides for greater variation in rod orientation. | 05-05-2011 |

20080300632 | Method of fabricating medical devices and medical devices made thereby - A method of fabricating medical devices and medical devices made from the method of fabricating a medical device, the medical device, without being exhaustive, may be a medical instrument, an implant, a prosthetic, a body support structure or the like. The method includes work-hardening a work-hardenable metal to achieve a desired microstructure of the metal, then fabricating a medical device in accordance with the desired microstructure utilizing the work-hardened metal. In one form, the desired microstructure is an elongated grain structure. The medical device is created from the grain-elongated metal such that the medical device is oriented relative to the plane of grain elongation. In a particular form of the invention, the medical device is a curved spine plate wherein elongated grains of the work hardened metal are oriented in a plane normal to a curvature of the spine plate. Work-hardening includes forging, cold rolling or hot rolling, and annealing prior to use in medical device fabrication. This creates a metal implant stock that has more strength and flexibility in compression and bending than without undergoing the present work-hardening. These properties are exploited in medical device design, fabrication, fabrication orientation and/or the like to create medical devices such as super strong implants. | 12-04-2008 |

A first spinal rod clamping member is provided on an end of the first connection member and defines first and second arced jaws that are adapted to clamp onto a first spinal rod. A second spinal rod clamping member is provided on an end of the second connection member and defines first and second arced jaws that are adapted to clamp onto a second spinal rod. Both the first and second clamping members are rotatable relative to the connection arms and thus provide the rotational adjustment. The individual and independent rotational adjustment of the spinal rod clamping members allows the present cross-connector to adjust to variations in skew between adjacent spinal rods as well as provide the ability to attach to the adjacent spinal rods at various angles between the adjacent spinal rods. | 01-15-2009 |
20090112318 | Foldable Orthopedic Implant - An orthopedic implant such as a spinal implant is made from a elastic biocompatible material (e.g. polyetheretherketone or PEEK) to provide a hinge that allows portions of the orthopedic implant to be folded into a closed position and to inherently deploy into an open position upon release of a folding bias. Hence, the orthopedic implant can accommodate a minimally invasive surgical procedure since the orthopedic implant can be introduced into the disc space in the closed position through a small-diameter insertion tube and then deploy to a particular height once the implant is released from the insertion tube (i.e. from release of the folding bias). The present implant is preferably, but not necessarily, made by injection molded PEEK. In this manner, the implant components are molded in the open position to cause the open position to be its innate position or form, thus allowing the implant to self-deploy (self-expand) when it is released from the folding bias. | 04-30-2009 |
