Japanese Ministry of Health, Labor and Welfare has approved St Jude Medicals' Penta surgical lead, designed for neurostimulation therapy to treat chronic pain.
The Penta surgical lead selectively stimulates nerve fibres associated with the patient's area of pain without affecting other areas.
It incorporates a proprietary micro-texturing process that enables greater amounts of current to be delivered via the small electrodes.
The Penta surgical lead can be used with the St Jude Medical Eon Mini spinal cord stimulator, which is the size of a man's watch, that makes it well suited for those patients whose body type requires a small device.
In addition to Japan, the Penta lead is also available in the US, Europe, Australia and Canada.
