An obstruction device includes an obstruction disc mounted on a proximal portion of a shaft. Anchoring members are disposed on the shaft on a proximal side of the obstruction disc. The anchoring members include a pair of loops which are orthogonal to each other, one being a longitudinal member and the other a latitudinal member. One or more support struts, which include one or more loops, are disposed on a distal side of the obstruction disc.
