Claim Text:
1. A method for preparing an implantable device, comprising: depositing a modification material onto at least a portion of a surface of an implantable device; post treating the implantable device with the deposited modification material, wherein post treating the implantable device includes annealing the implantable device at an annealing temperature for an annealing duration; and controlling at least one process condition during post treating the implantable device with the deposited modification material based on a target release rate of the deposited modification material into human tissue in an implantation environment, wherein controlling the at least one process condition includes controlling at least one of the annealing temperature or the annealing duration, wherein: the modification material includes silver; the implantable device includes a stainless steel surface; depositing the modification material includes depositing silver onto at least a portion of the stainless steel surface of the implantable device via electrolytic deposition, the deposited silver having a surface area coverage of about 0.1% to about 50%; post treating the implantable device includes annealing the implantable device with the deposited silver without substantially affect a mechanical property of the implantable device with the stainless steel surface, the mechanical property including one of tensile strength, compressive strength, yield strength, Young's modulus, ductility, and toughness, wherein the deposited and post treated silver has an interfacial shear strength of about 1 MPa to about 30 MPa; and the method further includes controlling at least one process condition when depositing the modification material by adjusting at least one of:
