Abstract
The present teachings provide a device and methods of making and using thereof. Specifically, one aspect of the present teachings provides a self-expandable device with a braided structure comprising a shunt, a distal retention flange, and a proximal retention flange. Upon the device being deployed at a treatment location, the distal retention flange or the proximal retention flange transitions to have a diameter that is greater than the diameter of the shunt portion. And the shunt portion has a braid angle θ. Another aspect of the present teachings provide that the ratio of flange/shunt diameter equals or greater than 1/sin θ. Yet another aspect of the present teachings provides an axial constraining mechanism to reinforce the shunt portion.
