Patent number: 7850718Abstract: A connecting device for spinal osteosynthesis has an osseous anchoring device, a connector that accommodates a joining shaft and is fixed to one end of the anchoring device, and a tightening device for immobilizing the joining shaft. The connecting device is characterized in that the connector is fixed to the anchoring device with the aid of a pin that penetrates the anchoring device and embodies a pivot joint. Furthermore, the device comprises an arrangement for stabilizing the connector relative to the anchoring device when the device is implanted in the patient, the stabilizing arrangement being located on the plane encompassing the shaft and the anchoring device.Type: GrantFiled: May 28, 2004Date of Patent: December 14, 2010Assignee: SpinevisionInventors: Stephane Bette, Dominique Petit, Didier Thibout, Gerard Vanacker

Patent number: 7651516Abstract: A connection assembly for spinal osteosynthesis has a bone-anchor having a connection zone intended to cooperate with a connection device, in which the connection device has, in its lower part, a spherical shape in order to permit a free positioning of the connection device in connector. The connector has a cavity of complementary shape to the spherical shape. This spherical shape forms a limit of longitudinal positioning with the connector.Type: GrantFiled: October 28, 2002Date of Patent: January 26, 2010Assignee: Spinevision S.A.Inventors: Dominique Petit, Stephane Bette, Muriel Cazin

Patent number: 6726692Abstract: This invention relates to an ancillary for a spinal osteosynthesis system comprising at least one implant that will be implanted in a spine. The implant comprises accommodation means located approximately along a centerline and that will accommodate at least one rod type connecting element. The ancillary comprises holding means that will cooperate with the said implant, and a manipulation means free to move with respect to the said holding means that will be used to manipulate the said connecting element. The said holding means will be arranged on one side of the accommodation means, and the said manipulation means comprises attachment means that will cooperate with the said implant on the side of the centerline of the accommodation means opposite the accommodation means. This invention also relates to a process for implantation of a spinal osteosynthesis system comprising at least one implant, using an ancillary.Type: GrantFiled: July 25, 2002Date of Patent: April 27, 2004Assignee: SpinevisionInventor: Stephane Bette

Patent number: 6083227Abstract: Bone screw for osteosynthesis devices comprising a screwing head and a screw-threaded shank having a transition portion having a variable profile between two shank parts of different profiles. The threading has a constant pitch and a constant outside diameter, and includes cutting crests throughout its length, including in the transition region. According to one method for manufacturing this screw, there are machined on the transition portion of the shank threads of decreasing depth up to the end of this transition region, the threads along the transition portion defining truncated, non-cutting crests. There is removed from the threads on the transition portion a sufficient amount of material for converting the non-cutting crests into sharp, cutting crests. This method provides a screw with bone anchorage capability throughout the length of the thread.Type: GrantFiled: September 21, 1998Date of Patent: July 4, 2000Assignee: SOfamor S.N.C.Inventors: Jean Saurat, Stephane Bette
