MECHANICALLY EXPANDABLE SHUNT IMPLANT

Abstract:

A shunt comprises a central flow portion configured to fit at least partially within an opening in a tissue wall. The tissue wall is situated between a first anatomical chamber and a second anatomical chamber and the opening represents a blood flow path between the first anatomical chamber to the second anatomical chamber. The central flow portion is further configured to maintain the blood flow path from the first anatomical chamber to the second anatomical chamber, prevent in-growth of tissue within the opening, and expand in response to expansion of the tissue wall.
