Patent number: 8906093Abstract: Bone implantable devices and methodologies permit careful application of biologically active substances and management of bone growth processes. The device includes a body defining a carrier receiving area for locating adjacent bone. Carrier material is located in the carrier receiving area. Substance is delivered onto carrier material through a port. A pathway delivers substance from the carrier receiving area to the bone surface. The body may be in the form of a spinal fusion cage, facet fusion screw, artificial joint, bone fixation plate, interbody graft, IM nail, hip stem, or other bone-to-bone appliances or bone-to-device appliances. In use, carrier is installed in the carrier receiving area of the device. The device is then implanted adjacent a bone. The substance is applied to the carrier for subsequent delivery to the bone. By doping carrier material after device implantation, inadvertent contact of the substance with non-target bone is more easily eliminated.Type: GrantFiled: July 30, 2013Date of Patent: December 9, 2014Assignee: DePuy Synthes Products, LLCInventor: David G.

Patent number: 8900306Abstract: Devices and methods for preventing the migration or expulsion of a nucleus disc replacement implant are provided. In one embodiment, an anti-expulsion device includes a body that is movable between a compressed configuration where it is adapted to fit through an opening in an annulus of a spinal disc, and an expanded configuration where it has a size that is larger than a size of the opening in the annulus of a spinal disc. The body can also include one or more mating features that allow the body to interact with a nucleus disc replacement implant and/or an annular wall of an annulus. As a result, since the body is larger than the opening of the annulus in the expanded configuration, the interlocking connection between the body and the nucleus disc replacement implant and/or annular wall will allow the body to prevent the nucleus disc replacement implant from being expulsed from the opening in the annulus.Type: GrantFiled: September 26, 2006Date of Patent: December 2, 2014Assignee: DePuy Synthes Products, LLCInventors: Brooke W.
