Reason for Recall
A safety concern exists regarding the Medtronic Activa Deep Brain Stimulation system instructions for performing MRI (magnetic resonance imaging). Medtronic's instructions have until now recommended a use of a displayed MRI head specific absorption rate (SAR) of not more than 0.4 W/kg. The recommended maximum displayed head SAR is now 0.1 W/kg.
Firm Action
The firm''s recall consists of providing revised instructions for the Activa DBS. The revision modifies the recommended SAR to use during MRI of patients who have an Activa DBS. Use of the Activa DBS is otherwise unaffected by this recall. A Dear Healthcare Provider letter and MRI Radiologist letter were sent on 11/30/05 and 12/05/05 to provide this information.
