April 10 (Reuters) - St. Jude Medical Inc said on Wednesday it received European regulatory approval for a brain implant used to treat primary and secondary Dystonia, a neurological movement disorder.
The maker of heart pacemakers, valves and other medical devices said European regulators approved its Brio, Kibra and LibraXP deep brain stimulation systems for managing symptoms of the incurable disease.
Dystonia causes a person's muscles to involuntarily contract and spasm, and can leave its victims wheelchair-bound.
For those who do not respond to medication, deep brain stimulation may help manage symptoms.
The device works by delivering electrical pulses to specific areas of the brain involved in controlling movement.
Dystonia is thought to affect more than 500,000 people in Europe.
Primary dystonia may be genetically inherited; the origin of the disorder is unknown. Secondary dystonia is considered environmental or symptomatic. It may result from a condition such as a stroke, or be a response to certain medications.
