Adding microscopic porosity to the surface of a microcoil to be used for medical implantation

摘要

A vasoocclusive microcoil for therapeutic treatment of a patient's vasculature includes a surface with a plurality of voids or pores therein, and a therapeutic or bioactive material disposed within the plurality of voids or pores. The therapeutic or bioactive material within the plurality of voids or pores operates to accelerate a healing process in the patient's vasculature when the microcoil is introduced into the patient's vasculature.
