A template for a valve construct for replacement of at least one of a mitral valve and a tricuspid valve includes at least an anterior leaflet portion and at least a posterior leaflet portion, each leaflet portion having a proximal edge, a distal edge, and side edges extending between the proximal edge and the distal edge. The template further includes a plurality of substantially straight elongated chordae portions each having a proximal end connected to the distal edge of one of the at least two leaflet portions and a distal end extending therefrom and one or more papillary muscle head portions formed at a commissure between distal ends of at least two of the plurality of chordae portions. A total width of the leaflet portions of the template is substantially equal to a circumference of a native annulus of a heart valve.

According to one aspect of the invention, a mandrel-less electrodeposition system for use in preparing a filament is provided. The system comprises: two or more static or rotating target electrodes having opposing, spaced-apart tips electrically-connected to an electrical power source, the opposing tips of the electrodes defining a deposition target axis; a nozzle electrically-connected to a second electrical power source and spaced apart from the target electrodes and the deposition target axis; and a reservoir configured to deliver a polymer composition through the nozzle and to the deposition target axis.

Methods, systems and devices are provided herein for preparing fiber matrices with differing degrees of anisotropy within a single matrix and controllable physical parameters, suhs as porosity.

A method of making a valve structure includes a step of rotating a mandrel and an electrodeposition target attached to the mandrel about a rotational axis of the mandrel.
