Stent retrievers
Solitaire 2
A non-bioabsorbable tubular device typically intended to be implanted into the base or parent artery of an intracranial aneurysm (e.g., wide-neck aneurysm situated at the base of a bifurcation) to facilitate the delivery of embolics to fill the aneurysm, facilitate clotting within the aneurysm by slowing blood flow into it, and/or to provide support for a neurovascular embolization coil placed inside the aneurysm. It is made of uncoated metal [e.g., nickel-titanium alloy (Nitinol)] and self-expands after it is delivered to the site of implantation and released (e.g., from a dedicated delivery instrument). Disposable devices associated with implantation may be included.
