Coated implantable medical device |
| abstract |
A medical device (10) includes a structure (12) adapted for introduction int o a patient, the structure (12) being formed of a preferably non-porous base material (14) having a roughened or textured surface (16). The structure (12 ) is conveniently configured as a vascular stent with a base material (14) of stainless steel, nitinol or another suitable material. The medical device (1 0) also includes a layer (18) of a bioactive material posited directly upon the roughened or textured surface (16) of the base material (14) of the structur e (12). The surface (16) of the base material (14) is roughened or textured by etching or by abrasion with sodium bicarbonate or another suitable grit. A preferred roughened or textured surface (16) is thought to have a mean surfa ce roughness of about 10 .mu.in. (about 250 nm) and a surface roughness range between about 1/.mu.in. and about 100 .mu.in. (about 25 nm and about 2.5 .mu.m). The particularly preferred use of sodium bicarbonate as the abrasive to provide roughness or texture to the surface (16) of the base material (14 ) of the structure (12) is additionally advantageous in the low toxicity of th e sodium bicarbonate to production workers, the ease of product and waste cleanup, and the biocompatibility of any residual sodium bicarbonate.</SDOAB > |
