The present invention relates to an implant made of a porous non-toxic material with a total open porosity larger than 5 percent by volume but not larger than 80 percent by volume within at least a portion of the implant. The implant is characterized in that: communicating pores with a pore size within the interval of 0.1-10 mu m occupy 10-80 percent of the total pore volume in said at least one portion of the implant; pores with a pore size within the interval of 10-50 mu m occupy not more than 5 % of the total pore volume in said at least one portion of the implant; and 5-40 % of at least one portion of the surface of the implant is covered by mainly evenly distributed pores having a pore size within the interval of 50-500 mu m. |
