Abstract: The disclosure provides example shunt apparatus and methods for deploying the apparatus. The apparatus includes (a) an inner catheter having first and second ends, where the inner catheter has a plurality of fenestrations extending along a portion of the inner catheter, (b) an outer catheter, where the inner catheter is positioned at least partially within a lumen of the outer catheter, (c) a deployment wire moveably arranged in a lumen of a conduit that is coupled to the outer catheter, and (d) a mesh arranged surrounding at least the first end of the inner catheter, where the mesh has a first end coupled to the inner catheter and the mesh has a second end coupled to the deployment wire, where the mesh is configured to move between a first position in an unexpanded condition having the form of a sheath to a second position in an expanded condition.
