DEEP BRAIN STIMULATION THERAPY: IMPORTANT INFORMATION REGARDING ENS CHARGE DENSITY WARNING

Models Affected: DBS Clinician Programmers using the A610 application

Description:

This notification provides important information regarding an issue wherein the charge density warning on the A610 software application does not appear at the expected time during test stimulation.  The A610 software includes a Charge Density Warning to alert clinicians during the test stimulation process of settings that may possibly damage nervous tissue.  Medtronic has identified during internal testing that under specific system configurations, the charge density warning will not display when expected; specifically, when the External Neurostimulator (ENS) is used during test stimulation with a twistlock cable and neurostimulation lead model 3387 or 3389.  In this configuration, the charge density warning on the A610 application will first appear at 60 mC/cm2/phase vs the expected 30mC/cm2/phase.

DEEP BRAIN STIMULATION THERAPY: IMPORTANT INFORMATION REGARDING THE DEEP BRAIN STIMULATION (DBS) LEAD DEPTH STOP

Models Affected: Models 3387/3387S, 3389/3389S, and 3391/3391S DBS Lead Kits

Description:

This notification provides you important safety information regarding the use of the depth stop accessory provided in all Medtronic Deep Brain Stimulation (DBS) lead kits. The Medtronic DBS depth stop, otherwise referred to as the lead holder, is used to establish the implant depth. The depth stop interfaces with parts of the stereotactic system used during surgery to control placement of the DBS lead tip to the target location. Medtronic has received complaints from physicians reporting that the DBS depth stop did not adequately secure to the lead. This letter provides information regarding this product performance issue, potential risk to patients, and actions to take regarding use of the Medtronic depth stop.

If you do not use the Medtronic depth stop (for example, if you only use the FHC, Alpha Omega, or Nexdrive depth stop), you are not affected and no actions are needed.

Urgent Medical Device Safety Notification – May 2016

Deep Brain Stimulation Therapy: Reported Events Related to Loss of Coordination

Models Affected: 37612, 37601, 37602, 7428, 7426

Description:

This physician notification provides important information on adverse events for DBS Therapy identified through Medtronic’s ongoing surveillance of reported events and published literature. One report has been identified of an inability to swim following DBS implantation and initiation of DBS therapy for Parkinson’s disease in a patient who was an experienced swimmer. Physicians and patients should be aware that loss of coordination is identified in labeling as a potential side effect of DBS therapy, and may result in, for example, the inability to swim. Patients should be made aware that participating in any activities requiring coordination that they were previously able to perform may place them in an unsafe situation; therefore these activities should be performed under supervision after DBS therapy is first turned on and after programming changes until any effects of their DBS therapy on coordination are understood.
