Patent number: 5423845Abstract: A blade for a surgical saw has an elongate body with distal and proximal ends, and a plurality of teeth formed on an outwardly facing edge surface of the distal end. The spaces between adjacent teeth are defined by surfaces which lie in planes which are non-perpendicular to the substantially flat surfaces which define the body of the blade. These non-perpendicular surfaces guide cuttings generated by the teeth laterally toward the flat surfaces of the blade and outwardly toward the proximal end of the blade as the blade advances in a cut. Each of the teeth formed on the edge of the blade has a pointed form. Approximately half of the teeth lie in a row in which the respective points lie in a first cutting plane which extends in parallel with, and lies adjacent a first side of, a plane which extends longitudinally through the center of the blade body.Type: GrantFiled: March 10, 1994Date of Patent: June 13, 1995Assignee: Biomet, Inc.Inventor: John M. McDaniel

Patent number: 5336226Abstract: A power operable bone facing cutter has a body with a pilot hole or stem for orientation with the bone to be faced. A cutter disk is removably fastened to the working end of the body and has a cutting edge lying in a plane perpendicular to the pilot axis. The cutting edge extends from a circle centered on the axis, outward to an outer circular edge. The cutting edge is at an angle with respect to a radius from the axis to cut toward the axis as the cutter is rotated. A chip escape slot is provided in the disk and body above the cutting edge. The rest of the bottom surface of the cutter disk is flat to provide a supporting surface spaced at a gage height from the plane of the cutting edge to provide optimum cutting while the supporting surface prevents excessively rapid or deep cutting, thus producing a skiving action.Type: GrantFiled: August 11, 1992Date of Patent: August 9, 1994Assignee: Chapman Lake Instruments, Inc.Inventors: John M. McDaniel, Michael W. Kiser

Patent number: 4501031Abstract: A prosthetic joint component which is comprised of a metal retainer and a plastic bearing portion which is molded integrally onto the top surface of the metal retainer. The metal retainer includes a plurality of notches spaced apart from each other around the periphery of the retainer. The notches enable the plastic, during the molding process, to flow through the notches to create a thickness of plastic completely surrounding the upper surface and the peripheral edge of the retainer (or metal base plate) and terminating in a lower plastic rim surface which is flush with the perimeter of the lower surface of the metal base plate, forming a strong mechanical interlock between the metal and plastic portions of the prosthetic joint component.Type: GrantFiled: January 22, 1981Date of Patent: February 26, 1985Assignee: Zimmer, Inc.Inventors: John M. McDaniel, Clayton R. Miller

Patent number: 4454612Abstract: A prosthesis having a porous polymeric coating over a non-porous polymeric substrate is disclosed. The porous polymeric coating is constructed by forming a mass of randomly arranged fibers of polymeric material in contact with a non-porous polymeric substrate of a compatible material. The entire prosthesis and mass of fibers is enclosed in a mold with interior dimensions conforming to the intended shape of the article. The mold is then subjected to an elevated temperature for sufficient time to sinter the fibers of the mass to each other and to the underlying substrate yet leave a pore volume of about 50%. The preformed material is ultra-high molecular weight polyethylene. Preferred sintering conditions are also disclosed.Type: GrantFiled: August 10, 1981Date of Patent: June 19, 1984Assignee: Biomet, Inc.Inventors: John M. McDaniel, Niles L. Noblitt

Patent number: 4136405Abstract: A knee joint prosthesis comprises cooperating femoral and tibial components and a coupling which is arranged to make a hinged connection therebetween. Interdisposed hinge knuckles and a cooperating pintle define a lateral-medial pivot axis that is located posteriorly of the intersection between the intermedullary femoral and tibial axes. A pair of transverse confronting plateaus transmit vertical load forces between the elements of the prosthesis. A proximal-distal axle and a cooperating tubular bearing afford rotational motion, and this motion is limited by a stop system, which system is also arranged to permit restricted distraction.Type: GrantFiled: April 29, 1977Date of Patent: January 30, 1979Assignee: Zimmer U.S.A.Inventors: Dan L. Pastrick, John M. McDaniel
