Internalization
Surgical procedure to implant the permanent pulse generator after successful trial stimulation.
Full Definition
Internalization is the second stage of a two-part neuromodulation implantation procedure, following a successful trial period. During internalization, the temporary external trial system is replaced with a permanent implantable pulse generator (IPG) that is surgically placed under the skin, typically in the buttock, abdomen, or chest area depending on the specific application. The previously placed leads remain in position and are connected to the permanent device through extension cables if necessary. This procedure is performed when trial stimulation has demonstrated significant therapeutic benefit, typically defined as 50% or greater improvement in symptoms.
Usage
Usage note: In neuromodulation context, refers specifically to device implantation, not psychological processes.
