1. A heart valve coaptation system for reducing regurgitation through the valve, comprising:

  • a flexible rail having a ventricular anchor on a distal end thereof adapted to anchor into tissue within a ventricle;

    a delivery catheter having a lumen defining a central axis through which the flexible rail passes and including a locking mechanism for fixing relative axial positions of the delivery catheter and flexible rail; and

    a coaptation member fixed on a distal end of the delivery catheter having an outer cover surrounding a compressible inner filler member and a generally cylindrical shape, the compressible inner filler member being mounted on the delivery catheter so that a majority of the filler member is radially offset from the central axis of the delivery catheter and the delivery catheter lies along one radial side thereof to form an offset spine of the coaptation member, whereinthe compressible inner filler member is an open cell foam that fills the space between the delivery catheter and the outer cover, and whereinthere are two types of open cell foam, with a majority being a first foam and a significantly stiffer second foam positioned in a thin region along the one radial side between the delivery catheter and outer cover.
