Abstract
Systems, devices and methods for heart valve prostheses are described. An implant is inserted proximate a mitral valve, and has a tubular body and a plurality of piercing members, the tubular body comprising an upper diameter and a lower diameter. Tissue proximate the mitral valve is engaged by the plurality of piercing members and the tubular body transitions from a first structural configuration to a second structural configuration by application of an expansive force to the tubular body proximate the upper diameter, the first structural configuration having the upper diameter smaller than the lower diameter and the second structural configuration having the upper diameter larger than the lower diameter.
