A new neurovascular stent system for treatment of brain aneurysms has been launched in Europe and the US.

The Neuroform EZ Stent System from Boston Scientific is a fourth-generation product intended for use with endovascular coiling to treat wide-necked aneurysms.

The new stent is designed to provide flexibility and conformability, especially in tortuous cranial blood vessels. It employs the Segmental Expansion technology, which is designed to improve stent anchoring.

The product features the hybrid cell design of prior-generation Neuroform stents, but incorporates a simplified, single-operator delivery system intended to facilitate the stent's delivery and positioning.

The first implantation of the Neuroform EZ Stent was carried out by Demetrius Lopes of the Rush University Medical Center in Chicago, and the first European procedure was performed by Professor Laurent Spelle of Foundation Rothschild Hospital in Paris.

"The Neuroform EZ Stent System performed well in a very challenging first procedure," said Dr. Lopes. "The smooth transfer of the stent into the catheter, combined with excellent support, stability and visibility, facilitated accurate stent placement."

"The improved delivery system of the Neuroform EZ Stent helped me to place the stent exactly where I planned," said Professor Spelle. "In my experience, Boston Scientific's new system is easier to use compared to its previous microdelivery system and should offer benefits for both physicians and patients."

"Boston Scientific is pleased to offer this new technology, which is designed to help physicians simplify these complex neurovascular procedures," said Mark Paul, President of Boston Scientific's Neurovascular Division.

Boston Scientific is a leading global supplier of interventional medical devices.
