Abstract
Transluminally implantable cardiac valves configured for use in cardiac valve replacement and/or cardiac valve exclusion that are capable of percutaneous delivery on low-profile catheters having 15 French size or less. The implantable cardiac valves are fabricated of from a unitary metal material to form a lattice frame support having a main body portion and valve leaflet portion, and a plurality of elongate biasing arm members. A polymer coating or covering is disposed on the valve leaflet portion and the elongate biasing arm members and subtends space between adjacent pairs of elongate biasing arm members to form valve leaflet portions in which the elongate biasing arms and the polymer coating operate to share a mechanical load thereupon.
