Abstract
A closure device to be inserted at least partially through a blood vessel wall aperture in a blood vessel wall. The closure device includes at least two parts, an internal part and an external part. The internal part is adapted to be extended at least partially through the blood vessel wall aperture and into the lumen to at least partially block the blood vessel wall aperture. Each of the internal part and the external part consists essentially of a metal that biodegrades within a living being in a period of time that permits biological repair of the blood vessel wall in and around the blood vessel aperture.
