Abstract
A spray system and method of using such spray system to fabricate a polymer membrane structure for use as a vascular graft or tissue engineered scaffold is provided. Generally, this spray system includes the use of at least two spray apparatus to apply different polymer and solvent mixtures to the outer surface of a mandrel to form a blended layer. Upon curing of the blended layer, phase separation occurs leading to the formation of a polymer membrane structure having variable properties along at least a portion of its longitudinal axis.
