Publication number: 20070099548Abstract: Iron and steel rolls are ground to production quality requirements with a grinding wheel that requires minimal wheel wear compensation, profile error compensation or taper error compensation during the grinding process. The grinding wheel consists essentially of a superabrasive material selected from the group of natural diamond, synthetic diamond, cubic boron nitride, and mixtures thereof, in a bond system, for a grinding wheel with extended wheel life, and which removes minimum amount of stock off the roll to achieve desired roll geometry.Type: ApplicationFiled: March 8, 2004Publication date: May 3, 2007Inventors: Kris Kumar, Biju Varghese

Publication number: 20070055243Abstract: A fastener assembly for a spinal fixation system that is particularly useful in treatment of pediatric and small-statured patients includes a fastener, an attachment member, and a locking member. The fastener has a lower portion for contacting a bone and an upper portion integral with the lower portion. The upper portion has two open channels. Each channel is configured and dimensioned to receive a portion of a longitudinal or connecting member along its circumference. The attachment member is positionable on the fastener and at least partially covers the channel that receives the longitudinal or connecting member. The locking member is operatively associated with the upper portion of the fastener and secures the attachment member and the longitudinal or connecting member to the fastener.Type: ApplicationFiled: August 25, 2006Publication date: March 8, 2007Inventors: Kris Kumar, Balaji Ramamurti, Barclay Davis, Thomas Runco

Patent number: 7137986Abstract: The present invention is directed to a transconnector for coupling first and second spinal fixation rods or other elongate fixation elements. The transconnector includes a male member, a female member, and a locking member. The male member has a body with a linking element (such as a hook) associated with the lateral end for receiving one of the fixation elements, and a projection on the medial end. The projection includes a recess defined by lateral and medial walls. The female member has a body with a linking element associated with the lateral end for receiving the other fixation element, and a cavity with an opening on the medial end for receiving a portion of the male member projection. The locking member secures the position and orientation of the male member projection portion in the cavity in order to accommodate different separation distances and orientations between the first and second fixation elements.Type: GrantFiled: March 15, 2004Date of Patent: November 21, 2006Assignee: Synthes (U.S.A.)Inventors: Thomas N. Troxell, G. Kris Kumar, Barclay R. Davis, Thomas J. Runco

Patent number: 5702485Abstract: A prosthetic device for the human hip having elongated fins or other like protrusions which are provided on the lower surface of a collar and which extend into previously formed slots or grooves in the bone. Either a plurality of fins, or a single fin having a non-rectilinear shape is provided. In one embodiment, previously formed fins are secured to a lower surface of the collar after formation of the collar. In this embodiment, pegs disposed on the fins preferably reside in correspondingly formed holes in the collar, or reside within slots extending inwardly from outer surfaces of the collar. Alternatively, the fins may be welded or otherwise bonded to the lower surface of the collar.Type: GrantFiled: February 16, 1996Date of Patent: December 30, 1997Inventors: Dennis W. Burke, G.
