NATURAL TISSUE HEART VALVE FIXATION

摘要

A natural tissue heart valve includes a tubular wall (13) having an outflow section (19) and valve leaflets (15) which allow flow into the outflow section (19). A heart valve (11) of this type is subjected to a fixative fluid to provide a first differential fluid pressure across the tubular wall (13) of the outflow section (19) and a second differential fluid pressure across the valve leaflets (15). The first differential fluid pressure acts outwardly on the tubular wall (13), and the differential pressures are unequal.
