20090270918 | Surgical Intervertebral Implant Forming a Swivel Joint - A surgical implant that supports and assists movement adjacent vertebrae including a top part and a bottom part associated with the spinous process of one of the vertebrae, each part including means for association with one process and reciprocal means or rotational association with the other part and forming a swivel joint. | 10-29-2009 |
20100234956 | EXPANDING CAGE FOR VERTEBRAL SURGERY - The disclosure relates to an expanding device intended to be implanted between the vertebral end-plates of two adjacent vertebrae, in particular for a stabilisation operation for intervertebral fusion. The inventive device comprises: a cage forming a peripheral part that surrounds a central cavity, said peripheral part being formed by a leading edge and a thicker manipulation edge which are connected by two lateral edges provided with lateral housings; and a retractor received in the lateral housings, which can be moved between an insertion position, in which it is located close to the manipulation edge, and a locking position, in which it is located at the leading edge, increasing the height of same. The invention is characterised in that the retractor is provided with abutment means designed to maintain the retractor in the locking position and to oppose the release of the retractor from the cage. | 09-16-2010 |
20100262246 | EXPANDABLE CAGE FOR VERTEBRAL SURGERY INVOLVING LUMBAR INTERSOMATIC FUSION BY A TRANSFORAMINAL POSTERIOR APPROACH - An implant of the intersomatic cage type, for fusion of vertebral bodies by a transforaminal approach, is disclosed that comprises a body with a curved profile that is designed to be implanted between the vertebral plates of two adjacent vertebrae. According to the invention, said body of curved profile comprises a posterior maneuvering part and an anterior attack part, said anterior attack part being composed of a lower tongue and of an upper tongue that are designed to receive between them a spacer element that can slide between a position of introduction, in which it is situated near said posterior maneuvering part, and a spacing position, in which it is situated near the end of said anterior attack part, thus increasing the thickness of the latter by spreading the tongues apart, said spacer element comprising a receiving seat that is open at the top and bottom. | 10-14-2010 |

20110218571 | ARTICULATED INTERVERTEBRAL SURGICAL IMPLANT TO ENCOURAGE CERTAIN INTERVERTEBRAL MOVEMENTS - The invention relates to a surgical implant intended to maintain and assist with the relative movement with respect to one another of two successive vertebras so as to obtain dynamic stabilization, said implant comprising an upper piece ( | 09-08-2011 |
20130123858 | MULTIAXIAL PEDICLE ATTACHMENT DEVICE FOR VERTEBRAL OSTEOSYNTHESIS - A multiaxial pedicle screw for vertebral osteosynthesis, including: a pedicle screw comprising a spherical head having a recess for the rotation of said pedicle screw; a socket that is hinged onto the spherical head of the pedicle screw and is provided with two diametrically opposed side grooves for receiving a connection rod; a tightening means for maintaining the position of the connection rod that is engaged into said socket; and a locking means that is positioned between said spherical head of the pedicle screw and the socket. The locking means is formed of a ring, at least the base or distal portion of which consists of a cold-compactible material having a resilient deformation capacity. Said locking means enables the locking of the socket in a desirable direction relative to the spherical head of the pedicle screw according to the position of the pedicle screw after the anchoring thereof. | 05-16-2013 |
