PROBLEM TO BE SOLVED: To provide a vasoocclusive embolic device deployment system to be used in placing an embolic coil at an affected region within a vessel. SOLUTION: The embolic coil (32) has a strip of stretch resistant fiber (40) whose distal end (46) is connected with the distal end part (38) of the coil. The stretch resistant fiber forms periodic wave portions (52) divided by straight portions. The stretch resistant fiber penetrates a lumen (16) of the embolic coil and the other end (48) is connected with the proximal end (42) of the embolic coil. The stretch resistant fiber may be attached to the embolic coil at an extra place between the distal end and the proximal end of the embolic coil. A head piece (44) attached to the proximal end of the embolic coil is helpful in connecting the embolic coil to a deployment catheter (14). COPYRIGHT: (C)2008,JPO&INPIT |
