Assignee:

Depuy Spine, Inc. - Raynham MA

International Classification:

A61B 17/56

US Classification:

606 60

Abstract:

A method of treating a fractured vertebral body by using a) a plurality of reinforcement rods combined with the b) a bone growth agent, wherein the reinforcement rods act to mechanically join disparate bone fragments across the fracture planes, thereby stabilizing the fracture site, and the bone growth agent promotes the growth of new bone across the fracture planes, thereby permanently replacing the fracture site with new bone.

Mark T. Hall - Bridgewater MA, US

Assignee:

DePuy Spine, Inc. - Raynham MA

International Classification:

A61F 2/44

US Classification:

623 1711

Abstract:

Methods and devices are provided for replacing a nucleus of a spinal disc, and in particular for preventing nucleus disc replacement expulsion. The nucleus of a spinal disc can be removed from the annulus by forming a small opening in the annulus. Once the nucleus is removed, one or more insert devices can be implanted within the annulus of a spinal disc and they can be mated to one or both endplates of the adjacent vertebrae. The insert(s) is configured to interact with a nucleus disc replacement implant to prevent expulsion of the implant from the annulus.

International Classification:

A61F 2/44

US Classification:

623 1715, 623 1716, 606297

Abstract:

A prosthetic is provided for replacing a vertebral disc. The prosthesis can comprise first and second endplates formed of a ceramic material, each including an articulating contact surface and a bone facing surface. The contact surface of the first endplate can have a shape complementary to the contact surface of the second endplate, thereby facilitating articulation of the first and second endplates while in contact with one another. The device can further include at least one non-ceramic bone attachment element mated with at least one of the bone facing surfaces, such that the bone attachment element covers less than a full area of the bone facing surface.

Assignee:

DePuy Spine, Inc. - Raynham MA

International Classification:

A61B 17/32

US Classification:

606170, 606 79, 606159, 606171

Abstract:

Disclosed herein are devices and methods for removing tissue. In one aspect, a device for removing tissue includes a hollow elongate member having an outer wall and a lumen, a selectively deployable tissue-cutting element extending from the hollow elongate member, and an actuation member extending through the lumen and coupled to the hollow elongate member at a location that is distal to the tissue-cutting element. Movement of the actuation member can cause the tissue-cutting element to move from the insertion configuration where the tissue-cutting element is not deployed to a tissue-cutting configuration where the tissue-cutting element is deployed such that it is radially extended relative to the insertion configuration.

International Classification:

A61B 17/70

US Classification:

606247

Abstract:

A implantable interference device configured for intra-facet placement within a facet joint is provided. The device includes a shank capable of engaging opposing faces of the facet joint. The shank can further include a head extending from a proximal end of the shank wherein the head is configured to engage and/or buttress opposing faces of the joint, and also configured for preventing over-insertion of the device. Optionally, at least a portion of the shank can include or be formed of a fusion-promoting bioactive material. Further, a method for providing fixation of a facet joint by intra-facet placement of an interference device within the facet joint is provided.
