METAL VASCULAR APERTURE CLOSURE DEVICE
First Claim
1. A closure device to be inserted at least partially through a blood vessel wall aperture in a blood vessel wall, the blood vessel having a lumen, the closure device comprising:
- at least two metal petals, each petal having a length, a width and a thickness, the width and thickness being such that the at least two metal petals can be inserted through the blood vessel wall aperture and into the lumen of the blood vessel, the length and the width being such that the length and the width prevent withdrawal of the at least two metal petals from the blood vessel through the blood vessel wall aperture when the length of at least one of the two metal petals is generally aligned with the blood vessel wall, the at least two metal petals having alignment features that tend to urge the at least two metal petals into alignment relative to each other;
a metal expansion member that is alterable from an unexpanded state to an expanded state, which, when in the unexpanded state, is advanceable to a location near the blood vessel wall and which when in the expanded state is limited in movement relative to the blood vessel wall; and
a bioabsorbable tensioning member that interconnects the at least two metal petals and the metal expansion member and that draws the petals and the metal expansion member toward each other upon being tensioned and that is securable to the metal expansion member to substantially maintain a relative positional relationship between the at least two metal petals and the metal expansion member upon being secured, whereby the at least two metal petals are positionable in the lumen adjacent to the blood vessel wall and the metal expansion member is limited in movement relative to the at least two metal petals and the at least two metal petals are stabilized in the blood vessel.

Abstract
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.

22. A method of substantially blocking fluid leakage from a blood vessel aperture in a blood vessel wall that exists in a blood vessel having a lumen, the method comprising:
-
inserting a closure device at least partially through the blood vessel wall aperture, advancing a first metal portion of the closure device through the blood vessel aperture into the lumen, the first metal portion having at least two parts and manipulating the at least two parts of the first metal portion such that the first metal portion is oriented against the blood vessel wall within the lumen and the at least two parts resist exiting the blood vessel through the blood vessel aperture; advancing a second metal portion of the closure device until the second metal portion is near the blood vessel;
wall;altering the second metal portion to expand transversely to substantially secure the second metal portion outside the blood vessel wall; pulling the first metal portion with a bioabsorbable tensioning member while shifting the second metal portion to a position closer to the first metal portion and to the blood vessel wall while expanding the second metal portion transversely; and securing the bioabsorbable tensioning member under tension such that the first metal portion and the second metal portion are substantially fixed relative to each other. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31)
