Patent number: 8992621Abstract: An expandable osteosynthesis implant has branches (5) each connected at one end to a seat (7) which is pierced by an orifice (8), suitable for being slid from a posterior direction between the facing faces of two consecutive vertebrae in order to hold them a given distance apart and restore stability of the spinal column. According to the invention, said branches (5) and said seat (7) define a hollow cage (1) which, in a “rest” position, has an outside general shape that is a cylinder of circular section, and a portion at least of the inside volume (9) of the cage (1) towards the distal ends of said branches (5) is in the form of a circular truncated cone whose large base is towards said seat (7) which implant has at least three branches (5) and, inside said inside volume (9) at least one spacer (2) suitable for passing through said orifice (8) and the large base of the truncated cone.Type: GrantFiled: April 16, 2013Date of Patent: March 31, 2015Inventors: Jean-Luc Chauvin, Liliane Attali, David Attia

Patent number: 8579976Abstract: 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.Type: GrantFiled: June 12, 2007Date of Patent: November 12, 2013Inventor: David Attia

Patent number: 8491657Abstract: The disclosure relates to an expanding device intended to be implanted between the vertebral end-plates of two adjacent vertebrae, in particular for a stabilization 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 characterized 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.Type: GrantFiled: March 25, 2008Date of Patent: July 23, 2013Inventors: David Attia, Francisco Ros Guillen

Publication number: 20130123858Abstract: 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.Type: ApplicationFiled: February 16, 2011Publication date: May 16, 2013Applicant: SMARTSPINEInventor: David Attia

Publication number: 20110218571Abstract: 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 (2) and a lower piece (3) which are intended each to be associated with the processus spinosus, or spinal process, of one of said vertebras, said pieces each comprising a means (4, 5) of association with a spinal process and means of connection to the other piece. According to the invention, said connecting elements are designed to collaborate in such a way as to form a pivot joint, at least one of said connecting elements being a visco-elastic element.Type: ApplicationFiled: June 12, 2007Publication date: September 8, 2011Inventor: David Attia
