Patent number: 8961519Abstract: A surgical rotary cutting tool and guard assembly is provided in which the cutting tool has a shaft with a proximal end and a distal end with an end effector at the distal end. The shaft includes at least one bearing mounted thereto intermediate the proximal and distal ends, the bearing having an inside dimension and the shaft having an outside dimension that provide for an interference fit between the bearing and the shaft. A tubular sleeve that serves as a guard houses the shaft, the sleeve having an inside dimension sized to slidably support the bearing.Type: GrantFiled: November 19, 2010Date of Patent: February 24, 2015Assignee: Zimmer, Inc.Inventors: Duane Lee Gillard, Eric Manojlovic, Jenna Ross, Jerry Lower

Publication number: 20100049321Abstract: An orthopedic device for repairing a cartilage defect and a method for utilizing the same. The orthopedic device includes an implant capable of attachment to bone, and a bearing portion extending from an exterior substrate of the implant. The implant may also include an anchor. The bearing portion includes a fibrous bearing surface configured to articulate against adjacent anatomical structures.Type: ApplicationFiled: April 15, 2009Publication date: February 25, 2010Inventors: Jerry Lower, Brian H. Thomas, James Mason, Kimberly Mimnaugh

Publication number: 20080287949Abstract: An intramedullary nail configured for use in a bone, the nail including at least one bore configured to receive a bone screw. The bore includes at least one member configured to engage the threads of the screw to prevent axial motion of the screw within the bore after application. The member may be integrally formed in the bore or may be a separate member added to the bore. The member may have a variety of cross sectional shapes, such as a rectangular shape, circular shape or a triangular shape.Type: ApplicationFiled: May 15, 2007Publication date: November 20, 2008Applicant: ZIMMER, INC.Inventors: Michael Keith, Tony Koser, Michael Wack, Michael Cordray, Steve Kitch, Jerry Lower

Patent number: 7419507Abstract: A prosthetic elbow for replacing an elbow of a dog or a human to restore normal, pain-free joint function. The elbow includes a humeral component for attachment to a humerus and a radioulnar component for attachment to an ulna. The humeral component includes a generally cylindric spool having a contoured external surface defining a first articular surface. The radioulnar component has a generally U-shaped contour with an inner peripheral surface defining a second articular surface sized and shaped for engagement with the first articular surface. Positional guides provide for implantation at precise locations.Type: GrantFiled: August 21, 2003Date of Patent: September 2, 2008Assignee: The Curators of the University of MissouriInventors: James L. Cook, Jerry Lower

Patent number: 6783529Abstract: A bone support structure is formed with opposing dynamization windows, and spacers of a bioresorbable material are positioned within the dynamization windows. The dynamization windows are longer than they are wide. The spacers may be integrally formed as a single insert. The bone support assembly is used with a bone fastener such as a bone screw which is advanced transversely through both the insert and the bone. The bone fastener is smaller across than the dynamization windows, so each spacer spaces the bone fastener relative to its dynamization window. As the spacers resorb, stress (at least in one direction) is increasingly transmitted through the fracture site rather than through the bone support structure. The positioning of the bone fastener, the shape and size of the dynamization windows and spacers, and the material of the spacers all allow design control over the type and amount of dynamization seen at the fracture site.Type: GrantFiled: October 19, 2001Date of Patent: August 31, 2004Assignee: DePuy Orthopaedics, Inc.Inventors: Anne Hover, Roy Sanders, Donald Martin Sturgeon, Jerry Lower

Patent number: 6709436Abstract: An intramedullary nail structure is formed with opposing dynamization windows, and spacers of a bioresorable material are positioned within the dynamization windows. The dynamization windows are longer than they are wide. The spacers may be integrally formed as a single insert. Tale nail is used with a bone fastener such as a bone screw which is advanced transversely through the bone and into the spacer, preferably in a bicortical attachment with the bone. The bone fastener is smaller across than the dynamization windows, so each spacer spaces the bone fastener relative to its dynamization window. As the spacers resorb, stress (at least in one direction) is increasingly transmitted through the fracture site rather than through the intramedullary nail. The positioning of the bone fastener, the shape and size of the dynamization windows and spacers, and the material of the spacers all allow design control over the type and amount of dynamization seen at the fracture site.Type: GrantFiled: May 22, 2000Date of Patent: March 23, 2004Assignee: Depuy Orthopaedics, Inc.Inventors: Ann Hover, Roy Sanders, Donald Martin Sturgeon, Jerry Lower, Neil Cowley, David Overaker, Charles Hoppe, Tom Poandl
