Publication number: 20160113693Abstract: A bone screw comprises a threaded shank including a distal end portion and a proximal end portion, and defining a first threaded section extending from the distal end portion toward the proximal end portion and adapted for anchoring in cancellous bone. A second threaded section extends contiguously from the first threaded section toward the proximal end portion. The second threaded section has a finer thread pattern relative to the first threaded section. In one embodiment, the first threaded section includes a first helical threading defining a single lead thread pattern for anchoring in cancellous bone, and the second threaded section includes a second helical threading interleaved with the first threading to define a duel lead thread pattern for engagement in cortical bone. In a further embodiment, the bone screw includes a head portion extending from the threaded shank and configured for coupling to a spinal implant.Type: ApplicationFiled: December 31, 2015Publication date: April 28, 2016Inventors: Francis Denis, Timothy A. Garvey, Joseph H. Perra, Manuel Pinto, James D. Schwender, Ensor Transfeldt, Michael Veldman

Patent number: 7803174Abstract: An orthopedic implant is disclosed having at least one passage for an elongated member that is compressible. In certain embodiments, multiple compressible elongated member passages may be provided, or an elongated member passage may be U-shaped and closable by a closure member. Split ring members may be provided in compressible passages and around elongated members. A bone anchor may be connected to the implant so that locking the anchor to the implant compresses one or more of the elongated member passages.Type: GrantFiled: November 4, 2005Date of Patent: September 28, 2010Assignee: Warsaw Orthopedic, Inc.Inventors: Francis Denis, Timothy Garvey, Joseph Perra, Manuel Pinto, James Schwender, Ensor Transfeldt, Michael S.

Publication number: 20050085743Abstract: An intraoperative neural monitoring system includes a power source and a simulator powered by the power source to deliver a cycle of electrical stimulation to a patient as a first group of positive or negative phase pulses automatically followed by a second group of pulses of opposite phase or polarity to the pulses of the first group. An activation performed to initiate delivery of the first group of pulses is effective to deliver the entire cycle of stimulation. A method of intraoperative neural monitoring involves activating a simulator to deliver a biphasic cycle of electrical stimulation to a patient during an operative procedure, delivering the entire cycle of electrical stimulation to the patient in response to the activating step and detecting EMG activity in the patient.Type: ApplicationFiled: January 12, 2004Publication date: April 21, 2005Inventors: David Hacker, Stanley Skinner, Ensor Transfeldt, Peter Sterrantino, Lionel Rupp, Katherine Rupp
