1. A method comprising:
positioning some or all of an implant comprising an embolic coil and a stretch resistant fiber within an aneurysm;
securing the implant to a delivery system by a key engaged to the stretch resistant fiber;
retracting a first portion of the embolic coil from the aneurysm;
limiting lengthening of the first portion of the embolic coil with the stretch resistant fiber as the first portion of the embolic coil is retracted from the aneurysm; and
releasing the key from the delivery system, thereby releasing the implant from the delivery system,
wherein:
the embolic coil comprises a lumen therethrough, the lumen comprising a first inner diameter in a non-expanded portion of the lumen and a second inner diameter in an expanded portion of the lumen;
the key comprises a proximal portion disposed proximally from the lumen and a distal portion disposed within the lumen;
the proximal portion comprises a first width measuring greater than the first inner diameter of the lumen; and
the distal portion comprises a second width measuring greater than the first inner diameter of the lumen and about equal to the second inner diameter of the lumen.
