摘要：
An apparatus and method for closing an arteriotomy site are disclosed which may employ the use of a delivery sheath within which is provided an anchoring device formed of memory metal wherein the anchoring device can be extended into the blood vessel itself. The memory metal, has a linear insertion configuration and obtains a non-linear or coiled configuration which can then be pulled back against the inner surface of the blood vessel to form a backstop. A biodegradable plug is then introduced into the tissue tract until it engages the backstop thereby ensuring proper positioning of the biodegradable plug. The anchoring device can then be retracted through the biodegradable plug leaving the arteriotomy site substantially closed with hemostasis being formed therearound.
