Penta Neurostimulator Approved by FDA

Karen Lee Richards Health Guide
  • A new five-column neurostimulation lead called the Penta, developed by St. Jude Medical, Inc., received FDA approval this month.  The Penta lead is the first of its kind, featuring the smallest electrodes in the market, which are arranged in five columns.

    According to St. Jude Medical, “This innovative surgical lead provides the broadest lateral electrode span of any neurostimulation lead on the market – yet the paddle configuration is only 10.9 mm wide. The Penta lead’s unique design is made possible by a proprietary micro-texturing process which enables greater amounts of current to be delivered via the small electrodes. The result is a lead that can more specifically focus current over a greater lateral area of the spinal cord, which may provide better coverage for managing hard to control chronic pain.“

    Neurostimulation therapy is used for managing chronic pain of the trunk and limbs and pain from back surgeries that have failed.  Neurostiumlators are small (about the size of a pacemaker) implanted devices that send little electrical impulses through a lead to electrodes which are implanted – usually in the epidural space near the spinal cord.  They work by blocking the transmission of pain signals to the brain.  The electrodes on the lead can be programmed to meet each individual patient’s needs.
