Abstract
Valve devices (10) useful in the treatment of various valve-related disorders and/or conditions are described. A valve device includes a leaflet (14) and a means (12) for biasing the leaflet in an open configuration. A method of making a valve device comprises the steps of determining a desired closing pressure; determining a desired opening pressure, selecting one or more valve leaflets; selecting an appropriate means for biasing the leaflet in an open configuration based on the determined closing and opening pressures; and attaching the one or more valve leaflets to the means for biasing the leaflet in an open configuration.
