1. An exclusion device for excluding fluid contact to an abnormality in a body flow lumen, comprising:
- a body portion having a wall portion and at least opposed first and second open ends;
a first and a second slot, extending through the wall portion of said body portion, adjacent said first open end, each of said slots being positioned in circumferential opposition to one another and separated from each other by portions of the wall portion extending to said first open ends;
a first biasing member received in said body portion and configured to bias said wall portion of said body portion in a radially outward direction;
a second biasing member maintained within said body portion adjacent said first open end and configured to bias said wall portion radially outward to the same, or less, extent as that provided by the first biasing member.
