A coil for the treatment of vascular aneurysms is disclosed. The coil is formed from filamentary members interlaced to form a three-dimensional substrate. The substrate is deformable between a collapsed state wherein it fits within a catheter, and an expanded state, which it assumes once deployed from the catheter into the vascular aneurysm. The three-dimensional shapes of the substrate include flat sheets biased into a helix or a tubular forms biased into figure eight loops, helical loops or a sinusoid. Bioactive characteristics may be imparted to the coil through the use of coatings or materials that provoke a healing response in living tissue.
