Abstract:
1. A method of producing a monolithic implant for use in tissue engineering, the implant having a structure comprising channels of 0.5-2 mm width and further comprising at least one porous region each having porosity in the range 100-1000 μm or less than 10 μm, said method comprising the steps of: i) plasticising at least one biocompatible material into a paste in water; ii) extruding the paste through a die being so dimensioned to impart said channel structure to the extruded material; iii) drying the extruded material to eliminate an aqueous and/or non-aqueous component; and iv) firing the dried extruded material to form said monolithic implant, wherein the paste in step (i) is made up from a first biocompatible material having a second biocompatible material dispersed within it.
