Patent number: 8262662Abstract: The present invention provides minimally invasive devices and methods for delivering a spinal connector to one or more spinal anchor sites in a patient's spinal column. In one embodiment, a spinal implant and access device is provided that includes a U-shaped receiver member, a bone-engaging member, and an extension member. The U-shaped receiver member can have a recess formed therein that is adapted to seat a spinal connector. The bone-engaging member can extend distally from the receiver member and it can be adapted to engage bone to thereby mate the receiver member to bone. The extension member can extend proximally from the receiver member and it can include a frangible portion formed thereon that is adapted to break when a predetermined force is applied thereto thereby allowing at least a portion of the extension member to be separated from the receiver member.Type: GrantFiled: November 20, 2006Date of Patent: September 11, 2012Assignee: DePuy Spine, Inc.Inventors: Timothy Beardsley, Douglas Bireley, James J.

Publication number: 20120226285Abstract: A bone filler delivery system comprises a longitudinal channel incorporates a perforated segment at least partially along, at or near its distal end. The channel can be sealed at its distal end so the filler material may be delivered only by the lumen and through the perforated segment. Optionally, said system comprises a permeable bag capable of being inserted into a bone while in collapsed configuration and then expanded when filled with bone voids filler. The mesh structure is designed to allow such permeable bag to expand to a predetermined size or shape under certain pressures and allows exudation of bone void filler through its walls. Extracting the permeable bag out of a treated body promotes flow of bone void filler through its pores into cancellous bone and/or cavity in the bone. The procedure promotes height restoration of the bone and introduces filler in a controlled manner.Type: ApplicationFiled: March 13, 2012Publication date: September 6, 2012Applicant: DePuy Spine, Inc.Inventors: Mordechay Beyar, Oren Globerman

Publication number: 20120165871Abstract: 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: ApplicationFiled: March 5, 2012Publication date: June 28, 2012Applicant: DEPUY SPINE, INC.Inventor: David G.
