Patent number: 11432850Abstract: A polyaxial bone anchor has a locking element shaped and configured to allow an anchoring member (e.g., a screw or hook) to polyaxially rotate at large angles about a central axis of the bone anchor before compression locking the anchoring member within an anchor head.Type: GrantFiled: February 14, 2020Date of Patent: September 6, 2022Assignee: DePuy Synthes Products, Inc.Inventors: William L. Strausbaugh, Sean Saidha, Boyd A. Wolf

Patent number: 10799273Abstract: A method and device for inserting screws into a patient, such that when the device is removed the device does not stick to the screw. The device, being a push-off driver, may have a handle, an inner driver, and a threaded driver sleeve having a button mechanism and a plurality of spheres, and an inner sleeve. The method includes the steps of assembling a push-off driver attaching a bone screw to the push-off driver inserting the bone screw and detaching the bone screw from the driver by unthreading the threaded driver sleeve from the polyaxial screw which causes the spheres in the recess of the inner driver to back up against the start of the recess and causing the threaded driver sleeve to “push-off” the polyaxial screw from the inner driver.Type: GrantFiled: October 9, 2018Date of Patent: October 13, 2020Assignee: DePuy Synthes Products, Inc.Inventors: Sean Saidha, William Strausbaugh, Boyd A.

Patent number: 10709479Abstract: An anchor assembly for use in spinal fixation to interconnect a longitudinal spinal rod, which is integrally formed with a body of the anchor assembly. The anchor assembly includes a bone anchor, a collet, a body portion, a rod portion, and a locking cap. The anchor assembly is preferably configured so that in use, the bone anchor may be secured to the patient's vertebra prior to being received within the body portion. The anchor assembly enables a surgeon to implant the bone anchor without the body portion to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the rod portion may be inserted into the rod-receiving channel of a second bone fixation element having a rod-receiving channel implanted at a second site and the body portion can be snapped-onto the bone anchor.Type: GrantFiled: November 26, 2018Date of Patent: July 14, 2020Assignee: DePuy Synthes Products, Inc.Inventors: Thomas Keyer, Eric McDivitt, Joseph Capozzoli, Boyd A.
