Stimulation of the Anterior Nucleus of the Thalamus for Epilepsy - Recruitment Stimulation of the Anterior Nucleus of the Thalamus for Epilepsy - Recruitment Rhythm

Completed

• Conditions: Epilepsy

• Registration Number: NCT00772421
• Lead Sponsor: MedtronicNeuro

Brief Summary

The primary objective is to demonstrate that a higher proportion of responders to deep brain stimulation (DBS) in the anterior nucleus (AN) of the thalamus in refractory epilepsy patients in the SANTE study exhibit a recruitment rhythm relative to non-responders.

Primary Outcome Measures

Name	Time	Method
To demonstrate that a higher proportion of DBS responders exhibit a RR relative to non-responders, using maximum tolerated voltage settings, at activated electrode contacts used for DBS stimulation in the SANTE study.	Study testing to occur during the long-term follow-up phase of the SANTE trial.

Secondary Outcome Measures

Name	Time	Method
For patients without a RR at their activated DBS electrode contacts used in the SANTE study, demonstrate that activating other electrode contacts generates a RR.	Study testing to occur during the long-term follow-up phase of the SANTE trial.
