Patent number: 9283088Abstract: An artificial intervertebral disc for implantation between two adjacent vertebrae includes superior and inferior shells connected in a ball and socket arrangement. The inferior shell preferably incorporating a convex portion that cooperates with a concave portion on the superior shell. A resilient nucleus is provided within an enclosure defined by the opposing inner surfaces of the shells and biases the shells against each other. The ball portion can be provided in either fixed or slidable arrangement. The artificial disc of the invention includes various resistance means for restricting and limiting the range of rotational and translational motion between the shells.Type: GrantFiled: June 12, 2008Date of Patent: March 15, 2016Assignee: Kinetic Spine Technologies, Inc.Inventors: R.

Patent number: 8057547Abstract: An artificial intervertebral disc for implantation between two adjacent vertebrae includes superior and inferior shells connected in a ball and socket arrangement. The inferior shell preferably incorporating a convex portion that cooperates with a concave portion on the superior shell. A resilient nucleus is provided within an enclosure defined by the opposing inner surfaces of the shells and biases the shells against each other. The ball portion can be provided in either fixed or slidable arrangement. The superior and inferior shells are also provided with cooperating male and female portions whereby the shells positively engage each other, thereby preventing separation, but allowing any desired articulation there-between. The artificial disc of the invention includes various resistance means for restricting and limiting the range of rotational and translational motion between the shells.Type: GrantFiled: November 20, 2008Date of Patent: November 15, 2011Assignee: Kinetic Spine Technologies Inc.Inventors: R.

Publication number: 20110230913Abstract: A facet joint prosthesis comprises a pair of facet elements for engaging the superior and inferior articular processes of a facet joint. The facet elements are provided with one or more articulating surfaces for articulating movement there-between. The facet elements are also provided with a positive engagement means for preventing separation of the elements and/or to limit relative movement there-between within a pre-determined range. In one aspect, the invention provides a spacer for positioning between the facet elements and for distracting the facet joint. The spacer may also serve to form an artificial lateral mass between the superior and inferior articulating surfaces. The spacer may be provided with engagement means for positively engaging one or both of the facet elements.Type: ApplicationFiled: April 15, 2011Publication date: September 22, 2011Applicant: KINETIC SPINE TECHNOLOGIES INC.Inventors: Stephan J.
