Bolton Medical Obtains CE Mark For New Relay NBS With Plus Delivery System

Bolton Medical has obtained CE Mark for its newly improved Relay NBS (Non-Bare Stent) Thoracic Stent-Graft with Plus Delivery System. The new system allows for improved covered-graft apposition in tightly curved aortas and expansion control in larger diameter anatomies during the treatment of complex thoracic aortic aneurysms.

Bolton Medical said that when a covered (or non-bare) stent is used in a tightly curved aorta, it can cause a gap or ‘bird beak’ in which the proximal end of the stent fails to lay flat against the inner curvature of the aortic arch, increasing the incidence of endoleaks and graft complications.

Additionally, in larger diameter anatomies, the graft may ‘retroflex’ or in-fold toward its inner curvature during deployment. The Relay NBS Thoracic Stent-Graft with Plus Delivery System has incorporated key design changes to reduce the potential for both these complications.

The Relay NBS Thoracic Stent-Graft with Plus Delivery System was CE marked in March 2010 and is expected to be available in Europe and all countries that recognise CE mark certification. It will be launched at the International Charing Cross Annual Symposium in London at Bolton Medical Symposium on 12 April, 2010.

Relay and Relay NBS Endovascular Stent-Grafts are indicated for the treatment of main thoracic aortic pathologies such as aneurysms, penetrating ulcers, pseudoaneurysms and intramural hematomas in adult patients. As of today, more than 3000 patients have been treated world-wide with Relay and Relay NBS Stent-Grafts.
