The FDA has given MicroVention, a division of Terumo, approval for the company’s Low-Profile Visualized Intraluminal Support Device (LVIS and LVIS Jr.). The self-expanding nitinol stent, which comes with its own delivery mechanism, is used to repair brain aneurysms.
The stent is placed across the neck of the aneurysm and provides support for the blood vessel affected. Then soft platinum coils are pushed into the aneurysm, bunching together and blocking blood flow into the dilated space. The stent prevents the coils from exiting the aneurysm and maintains the pressure on the coils necessary to keep the aneurysm under control.
The device, which comes in two sizes, features radiopaque markers and flared ends to help with positioning of the stent under fluoroscopy.
