Abstract
Various inserts, called shapers and spacers, are provided for controlling tissue engineered heart valve (TEHV) leaflet geometry during culture. These inserts will prevent TEHV leaflet retraction during culture, be able to control the leaflet geometry during culture, enable culturing TEHV leaflets with a larger coaptation area, control the height of the coaptation area, maintain TEHV leaflet curvatures, and/or enable possibilities to culture TEHV leaflets in open configuration.
