1. An embolic implant comprising:
an embolic coil comprising a coiled wire;
a detachment feature affixed to the embolic coil approximate a proximal end of the embolic coil, the detachment feature comprising a first engagement surface and a second engagement surface longitudinally offset from each other by a length approximately equal to half of a diameter of the coiled wire; and
a stretch resistant fiber engaged to the detachment feature, extended through a lumen of the embolic coil, and affixed to the embolic coil approximate a distal end of the embolic coil,
wherein the detachment feature comprises a first opening therethrough and a second opening therethrough separated from the first opening,
wherein the stretch resistant fiber passes through the first opening,
wherein at least a portion of the first opening is positioned within the lumen of the embolic coil,
wherein at least a portion of the second opening is positioned proximally from the proximal end of the embolic coil, and
wherein the second opening comprises an approximately polygon shape comprising four sides of approximately equal length and a fifth side of greater length than the four sides, the fifth side being orthogonal to a longitudinal axis of the detachment feature.
