A method of forming an electrospun prosthetic valve includes utilizing a rotatable and angularly adjustable prosthetic valve mold. The prosthetic valve mold is set to a first angle. The prosthetic valve mold is rotated at a first rotational velocity and a first layer of electrospun fibers is deposited on the prosthetic valve mold. The prosthetic valve mold is stopped and a frame is positioned overthe first layer. The prosthetic valve mold is set to a second angle. The prosthetic valve mold is rotated at a second velocity and a second layer of electrospun fibers is deposited on an outer surface of the first layer and an outer surface of the frame. 一种形成电纺人工瓣膜的方法包括使用可旋转且可角度调节的人工瓣膜模具。将所述人工瓣膜模具设定为第一角度。以第一旋转速度旋转所述人工瓣膜模具，并且将电纺纤维的第一层沉积在所述人工瓣膜模具上。停止所述人工瓣膜模具并且将框架定位在所述第一层上。将所述人工瓣膜模具设定为第二角度。以第二速度旋转所述人工瓣膜模具，并且将电纺纤维的第二层沉积在所述第一层的外表面和所述框架的外表面上。
