Obstruction device

An obstruction device comprising:

• an obstruction disc mounted on a proximal portion of a shaft, said obstruction disc being convexly shaped so as to taper to a smaller diameter towards a distal end of said shaft, a center of said obstruction disc being located at a junction of said obstruction disc and said shaft and a longitudinal axis extends along said shaft passes through said center;
• anchoring members disposed on said shaft on a proximal side of said obstruction disc,
• wherein said anchoring members comprise a pair of loops which are orthogonal to each other, one being a longitudinal member and the other a latitudinal member, and
• one or more support struts disposed on a distal side of said obstruction disc, said one or more support struts comprising one or more loops, each of said one or more loops comprising a first V-shaped portion that is located at the distal side of said obstruction disc, wherein an apex of said first V-shaped portion is located on said longitudinal axis and said first V-shaped portion extends from said center of said obstruction disc to two radially opposing points located at the distal side of said obstruction disc, said first portion curving distally into a second V-shaped portion that is located more distally from the distal side of said obstruction disc than said first V-shaped portion and wherein an apex of said second V-shaped portion is located on said longitudinal axis.
