1. A shunt apparatus, comprising:
an inner catheter having a first end and a second end, wherein the inner catheter has a plurality of fenestrations extending along a portion of the first end of the inner catheter and in fluid communication with a lumen of the inner catheter;
an outer catheter, wherein the inner catheter is positioned at least partially within a lumen of the outer catheter;
a deployment wire moveably arranged in a lumen of a conduit that is coupled to the outer catheter, wherein the lumen of the conduit is in communication with the lumen of the outer catheter such that a portion of the deployment wire is moveable within the outer catheter; and
a mesh arranged surrounding at least the first end of the inner catheter, wherein the mesh has a first end fixedly coupled to a proximal tip of the first end of the inner catheter and the mesh has a second end housed in the outer catheter and coupled to a first end of the deployment wire, wherein, in response to movement of the deployment wire, the second end of the mesh is configured to advance through the outer catheter and 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.
