| abstract |
This invention is an implantable device that is attached to the exterior of an aneurysm, or to the exterior of some other portion of a blood vessel wall, wherein this device elutes, or otherwise emits, an emitted substance to prevent or treat vasospasm. This device may be embodied as a magnesium-eluting aneurysm clip. A magnesium-eluting aneurysm clip not only stops blood from escaping out of the aneurysm, but it also helps to prevent vasospasm from any blood that has already escaped. |
