20100049327 | Method and Apparatus for Removing a Bearing - A system for replacing a portion of a shoulder joint can include a tray having an outer surface and an inner surface. The outer surface can be adapted to engage a humeral stem. A bearing can include an outer bearing surface and an inner articulating surface. The outer bearing surface can be positioned adjacent to the tray. A ring can be selectively disposed between the tray and the bearing. The ring can define an annular body having a slit formed therein. The ring can be movable between a locked position wherein the ring retains the bearing relative to the tray and an unlocked position. A removal tool can define a proximal end and a distal end. The distal end can define a ring engaging surface and a bearing engaging surface. The ring engaging surface can be adapted to engage the ring at the slit such that the ring expands radially from the locked position away from engagement with the bearing to the unlocked position. The bearing engaging surface can be adapted to engage the bearing and urge the bearing away from the tray. | 02-25-2010 |

A central peg fixation mechanism is provided that is configured to couple an optional central fixation peg to the medial surface. | 02-10-2011 |
20110184424 | METHOD AND APPARATUS FOR REMOVING A BEARING - A method for removing a bearing that is coupled to a prosthetic implant by a ring includes advancing a distal end of a removal tool in a first direction and into a slit formed in the ring. The ring can be caused to expand radially from engagement with the bearing. The distal end of the removal tool can be advanced in a second direction such that the removal tool engages the bearing. The distal end of the removal tool can be further advanced in the second direction such that the removal tool urges the bearing away from the prosthetic implant. | 07-28-2011 |
