Patent attributes
A medical device having at least one expandable stent, and at least three removable slat members carried by the stent. The removable slat members provide a substantially continuous cover for the medical device, and thus impede the flow of blood through the peripheral walls of the medical device. When deployed within a blood vessel, some of the slat members may serve to cover an aneurysm and restrict the blood flow into the aneurysm. In addition, one or more of the slat members may be selectively removed to provide blood flow into a branching blood vessel. In an alternative embodiment, an inner expandable stent is coaxially disposed within the outer expandable stent, and three removable slat members are carried by the inner expandable stent.
