Abstract: An implantable composition of a biocompatible porous metal for enhanced tissue in-growth and fixation in the body. The metal has a porosity greater than 80% and up to about 95% which allows good cell population, yet it also provides structural integrity and stability allowing its use as a weight-bearing implant. In various embodiments, the metal may be titanium, which includes titanium alloys, or may be a cobalt-chromium-molybdenum alloy. The high porosity desirably facilitates in-growth of cells and/or tissues, which in turn facilitates biological fixation and biocompatibility. This is beneficial, for example, in an orthopedic implant such as a hip replacement, for facilitating in-growth of connective tissue and bone cells. The porous composition is structurally stable.

Abstract: This invention is directed to an electronic lottery game system utilizing multiple player-activated video terminals that are linked to computers performing centralized game draw and accounting functions. Each player places a wager and selects his lottery draw choices. The system enrolls the player in a future lottery game after the player makes his choices. The system automatically draws the lottery numbers. The result of the selected game is displayed at the player's terminal in such a manner as to provide the excitement of a real time game.
