Abstract
An implantable electrode of the type in which an elongated wire coil forms the electrode surface. The electrode coil is mounted around an insulative lead body and is stabilized on the lead body by means of a plastic filler between the individual turns of the electrode coil, extending radially outwardly to approximately one-third of the diameter of the electrode coil wire. The filler is produced by stretching a portion of the lead body which normally displays an outer diameter greater than the inner diameter of the electrode coil sliding the electrode coil over the lead body, inserting an expandable mandrel into the lead body and expanding the mandrel to urge the lead body into contact with the electrode coil. This assembly is then heated to encourage flow of the lead body into the spaces between the electrode coil to stabilize the coil on electrode body and to present fibrotic ingrowth around the electrode coil wire.
