20120065739	Method of Making Porous Metal Articles - In one embodiment, the present invention may be a method of making a porous biocompatible metal article by combining a metal powder with a homogenizing aid to form metal granules, including blending the metal granules and an extractable particulate to form a composite, forming the composite into a green article, removing the extractable particulate from the green article to form a metal matrix and pore structure, and sintering the metal matrix and pore structure. Furthermore the present invention may include a second homogenizing aid combined with the extractable particulate. The present invention also includes shaping the metal matrix and pore structure with or without the use of a binder.	03-15-2012
20100180724	Porous Metal Articles Having A Predetermined Pore Character - A porous metal article having a predetermined pore structure. The porosity is provided by the use of an extractable particulate in a powder forming route to create a desired porosity. Extraction of the pore forming particulate prior to sintering of the powder minimizes contamination of the sintered article and allows for the processing of material sensitive to contamination such as titanium. Added functionality can be gained by co-forming the porous material with non-porous material to create an article with layers of differing characteristics. The article is suitable for use as an implant body is porous enough to facilitate tissue in-growth and bony fusion.	07-22-2010
