Neurostimulator with AnkerStim lead

A NEW TREATMENT
FOR INTRACTABLE
CHRONIC CLUSTER
HEADACHE PATIENTS

Occipital Nerve Stimulation
(ONS) with AnkerStimTM

ONS: A PROMISING NEW TREATMENT OPTION

For those with intractable Chronic Cluster Headache (iCCH), there is a new treatment option available: Occipital Nerve Stimulation (ONS) using the AnkerStimTM lead. ONS is a promising option for patients with iCCH and may reduce attack frequency and intensity, as well as medication use.

ANKERSTIMTM: AN INNOVATIVE LEAD DESIGNED TO REDUCE COMMON COMPLICATIONS

The AnkerStimTM lead is designed to resist migration and improve comfort.

ANKERSTIM: AN INNOVATIVE LEAD DESIGNED TO REDUCE COMMON COMPLICATIONS
  • Lead tip features a dual-prong tine for lead fixation in the subcutaneous layer. Two additional single-prong tines provide extra fixation between the two proximal electrodes. These tines are designed to resist migration and avoid the use of anchors in the occipital area that were a source of discomfort at the implant site.
  • Flexible spring-coil electrodes adjust to the shape of the skull and are designed to improve comfort at the device site and lower the risk of skin erosion.
  • 14G curved introducer needle adjusts to the curvature of the skull to help facilitate lead implant.
  • 60 cm lead length allows for two strain relief loops along the lead trajectory intended to further resist lead dislodgement.

HOW ONS WORKS

  • Leads are connected to an implanted neurostimulator via an extension.
  • Electrical stimulation targets occipital nerves and may evoke the sensation of paresthesia.
  • Stimulation is thought to work by interfering with pain signals and possibly restoring balance with non-functioning nerves.
  • An external handheld programmer allows physicians to set and adjust patient stimulation parameters in clinic.
  • Patients can adjust stimulation settings and turn their system on and off using their MyStim wireless device.
HOW ONS WORKS

WHAT DO THE EXPERTS THINK?

AnkerStim™ was developed on the initiative of Prof. Jean-Pierre Van Buyten and Dr. Iris Smet. Listen to their thoughts regarding ONS, Cluster Headache and AnkerStimTM, and watch them guide us through an implant procedure.
