METHOD OF BIOMEDICAL MATERIAL PRODUCTION AND MATERIAL PRODUCED THEREUNDER Russian patent published in 2008 - IPC A61L27/04 A61L27/06 A61L27/24 A61F2/28 

FIELD: medicine.

SUBSTANCE: method of biomedical material production based on titanium and cobalt alloy in mode CBC includes as follows. Exothermal mixture of raw reagents made of powdered titanium and cobalt is prepared, added with max. 4 wt % titanium hydride and max. 15 wt % amorphous nanodisperse powdered calcium hydroxyapatite (CHA) or nanocomposite calcium hydroxyapatite with biopolymers. This powdered raw mixture is pressed to preparation blanks placed to reactor CBC. Preparation blank is preheated to temperature 350-580°C. Combustion action is initiated in inert atmosphere with following release of end product. Produced biomedical material represents mushy alloy of formula TiCo of total porosity 55-70% at open porosity portion 90-98% with prolate pores sized 200-800 mcm. Pore partitions are also porous with prevailing round pores of diameter ca 100 microns. Surface of mushy alloy is coated with calcium, phosphor and oxygen compounds which are hydroxyapatite decomposition products with prevailing content of calcium perovskite.

EFFECT: material is noncytotoxic, cells are characteristically split and actively migrate inside of mushy space.
