Abstract
A heart valve with reinforced leaflets is provided. The free edge of the leaflet and/or the leaflet belly area of the leaflet has a circumferentially aligned band of aligned electrospun fibers with non-aligned fibers. The aligned and/or the non-aligned fibers are bioabsorbable polymer fibers, and are capable of being replaced over time with newly formed tissue. A method is provided to make these heart valve leaflets using two sources of electrospinning which electrospun simultaneously to either form distinct layers or intermixed layers of aligned and non-aligned fibers.
