Abstract: A prosthetic hip replacement assembly comprises a femoral stem, a femoral head adapted to be fixedly secured to the femoral stem, an acetabular shell adapted to be inserted into a surgically prepared acetabulum, and a liner fixedly secured within the acetabular shell and within which the femoral head is adapted to fully articulate. The femoral head comprises a ball, a highly porous coating, and a plastic coating formed upon the highly porous coating such that the plastic coating can infiltrate the pores of the highly porous coating whereby the femoral head comprises a monobloc structure comprising the ball, the highly porous coating, and the plastic coating. In an alternative embodiment, the liner can be eliminated.

Abstract: A suction tip and tubing aspirator is disclosed and comprises a first lumen having a first open end adapted to be operatively connected to a source of suction, and a second open end adapted to be inserted into a site from which tissue or debris is to be aspirationally removed, a second lumen integrally connected to the first lumen, and a stylus movably disposed within the second lumen between retracted and extended positions such that when the stylus is moved from the retracted position to the extended position, a distal end portion of the stylus will protrude outwardly from the second end of the first lumen so as to remove any tissue or debris which has clogged, blocked, or occluded the second open end of said first lumen.
