Patent number: 9011549Abstract: A trial device and a method for using the device in surgery are disclosed. The device includes a body including a proximal portion and a distal portion. The proximal portion has a post or trunion projecting therefrom. The distal portion extends from the proximal portion and includes a first arm and a second arm, the first and second arms being movable with respect to one another. The body further includes a cavity formed therein so as to extend through the proximal portion and into the distal portion. The device further includes a driver adapted for sliding engagement within the internal cavity of the body such that movement of the driver, preferably in a distal direction, causes movement of a portion of the first arm away from a portion of the second arm.Type: GrantFiled: June 18, 2012Date of Patent: April 21, 2015Assignee: Howmedica Osteonics Corp.Inventors: Roy Philip Splieth, Shawn Michael Kroll

Patent number: 8876907Abstract: A prosthetic glenoid component has a body having a concave bearing surface and a convex glenoid contacting surface. First and second pegs extend outwardly from adjacent respective first and second ends of the bone contacting surface of the body, the first and second pegs have portions with a first diameter at the bone contacting surface extending for a first length and a second diameter extending from the first diameter for a second length, the first diameter larger than the second diameter. A third peg extends outwardly from the bone contacting surface intermediate the first and second pegs. The third peg has a third diameter greater than the second diameter portion of the first and second pegs and a third length greater than the first length of the first diameter portion of the first and second pegs. The third length is less than the sum of the first and second lengths.Type: GrantFiled: July 26, 2012Date of Patent: November 4, 2014Assignee: Howmedica Osteonics Corp.Inventors: Alexandre A. N. Baptista, Jeffrey Duncan Sander, Shawn Michael Kroll, Gerald Rosenberg

Patent number: 6554127Abstract: The invention relates to a power & free conveyor which comprises a free rail (3) and a power chain (1) that follows said free rail (3), to a large extent, in a parallel manner. A transport carriage (4) provided with a front runner (5) and a rear runner (6) are arranged on the free rail (3). The front runner (5) and the rear runner (6) each comprise a carrier (11, 14) that can pivot between two positions. In an area of the movement path of the transport carriage (4), the course of the power chain (1) deviates from that of the free rail (3) so that the transport carriages (4) can no longer be moved via the front runner carrier (1) thereof. Instead, the transport carriage is pushed by the interaction between a chain carrier (2) and the rear runner carrier (14) that is swung out into a carrying position. The rear runner carrier (14) comprises two stabile positions which can be changed by overcoming a resistance.Type: GrantFiled: December 7, 2001Date of Patent: April 29, 2003Assignee: Eisenmann Maschinenbau KGInventor: Michael Kroll
