Abstract
The present invention generally provides an implantable medical lead having markings. The lead is easier to implant and improves the accurate localization of lead electrodes at a specific point of the brain for neurostimulation. Also provided is an implantable medical lead having a removable extension that advantageously provides a minimal length of excess lead protruding from the lead insertion site. The improved lead and method of implantation facilitates use of a neurostimulator device that is implanted directly in a patient'"'"'s cranium.
