20110009900 | METAL VASCULAR APERTURE CLOSURE DEVICE - A closure device to be inserted at least partially through a blood vessel wall aperture in a blood vessel wall, having at least two metal petals that can be inserted through the blood vessel wall aperture and into the lumen of the blood vessel. The petals are structured to prevent withdrawal through the blood vessel wall aperture when the length of the petal is generally aligned with the blood vessel wall. The metal petals have alignment features that tend to urge them into alignment relative to each other. The closure device includes a metal expansion member that is alterable from an unexpanded state to an expanded state. A bioabsorbable tensioning member interconnects the petals and the metal expansion member and is securable to the metal expansion member. | 01-13-2011 |
20110009901 | METAL VASCULAR APERTURE CLOSURE DEVICE - 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. | 01-13-2011 |
