Abstract
A vasoocclusive embolic delivery system for use in placement of an embolic coil at a treatment site within a vessel. The embolic coil includes an elongated stretch resistant fiber having its distal end bonded to the distal end of the embolic coil. The stretch resistant fiber extends through a central lumen of the coil and extends beyond the proximal end of the coil. Also included is a generally cylindrical stabilization bead, having a diameter slightly smaller than the diameter of the central lumen of the coil, mounted on the stretch resistant fiber within the lumen of the embolic coil. The stabilization bead serves to keep the stretch resistant fiber centered within the lumen of the embolic coil. Additionally, a headpiece is mounted on the proximal end of the stretch resistant fiber and serves to couple the embolic coil to the delivery system.
