Publication number: 20060260483Abstract: A device for elastically stabilizing vertebral bodies includes at least two bone anchoring means, each having a central axis and a head segment. The device also includes elastic means that can be joined to the head segments of two adjacent bone anchoring means in such a manner that the longitudinal axis of the elastic means extends transversely to the central axes of the bone anchoring means. Under compressive loads, the elastic means has a progressive spring characteristic. The elastic means is manufactured from a metallic material and has a plurality of spring coils, of which at least two spring coils have a geometric dimension which is different from the other spring coils.Type: ApplicationFiled: March 29, 2006Publication date: November 23, 2006Inventors: Stephan Hartmann, Armin Studer

Patent number: 6547789Abstract: A holding apparatus for the vertebra of a spinal column. It furthermore has a mount for a bar which is provided at the side of the holding apparatus which faces away from a clamping screw. The clamping screw of the holding apparatus produces a rigid connection of the holding apparatus to the bar which is located in the mount. The apparatus retains the bar in the mount and can be brought into connection with the holding apparatus so as to temporarily retain in the mount a bar which is introduced into the mount until the holding apparatus is fixed to the bar by way of a rigid connection.Type: GrantFiled: May 26, 2000Date of Patent: April 15, 2003Assignee: Sulzer Orthopedics Ltd.Inventors: Carlo Ventre, Cosimo Donno, Armin Studer, Onur Adali, André Lobsiger, Daniel Hug, Raffael Berani, Daniel Ambühl
