Patent ID: 8914132

Claim:
A method to manufacture an implantable medical lead having a lead body with a distal end, a proximal end, and a hollow interior proceeding between the distal end and the proximal end, the method comprising: manufacturing a connector pin with a configuration to mechanically and electrically attach the proximal end of the lead body to an electronic device, and with an inner bore proceeding through the connector pin; attaching the connector pin to the proximal end of the lead body; introducing an inner coil from the distal end of the lead body through the inner bore of the connector pin, and leaving the inner coil so that the inner coil protrudes a distance beyond a proximal end of the connector pin; the method further comprising: forming a first sub-assembly by attaching a header, containing a fixation arrangement to the inner coil; assembling a second sub-assembly comprising an outer casing of the lead body and a connector; assembling the first and second sub-assemblies by introducing the proximal end of the inner coil into a distal end of the outer casing to cause the proximal end of the inner coil to project from the proximal end of the connector pin; cutting the inner coil to a selected length at the proximal end of the connector pin; and attaching the proximal end of the inner coil to the proximal end of the connector pin.
