Kinetra for Deep Brain Stimulation

Leads & Extensions

Leads

DBS Leads are 4 thin, insulated, coiled wires bundled within polyurethane insulation. Each lead has 4 electrodes at the tip. These quadripolar leads deliver stimulation using either one electrode or a combination of electrodes.

There are 3 leads available for the Kinetra DBS system:

  • The Model 3387 DBS lead has 4 electrodes spaced 1.5 mm
    apart
  • The Model 3389 DBS lead has 4 electrodes spaced 0.5 mm
    apart
  • The Model 3391 DBS lead* has 4 electrodes spaced 4 mm
    apart

Extensions

Deep brain stimulation (DBS) extensions are insulated wires that run subcutaneously along the head, neck, and shoulder to connect the lead to the implanted neurostimulator.

ACCESSORIES
Stimloc

The Stimloc™ lead anchoring device and burr hole cover offer a complete solution for easy and accurate DBS lead stabilization. Stimloc assures secure lead positioning after implant, while its low profile enhances patient comfort and safety.
Stimloc Accessories

In the unlikely event that any component of the Stimloc is dropped out of the sterile field, the Stimloc accessory kit (Model 3550S-01) offers sterile replacement components. The sterile screwdriver (Model 3550S-02) is also available in an accessory kit as backup when attaching the Nexframe System or Stimloc Device.
Tunneling Tools

The tunneling tool's combination of length and obturator-tip designs provide multiple options for various patient anatomies.
