Abstract

Elastomeric fibrous constructs are formed from multicomponent, non-woven nano-/microfibers having a core and sheath configuration made primarily of an absorbable polymer and preferably a water-soluble one, respectively. Most preferably, the nano-/microfibers are produced by electrostatic spinning. Depending on clinical use of these constructs, suitable bioactive agents can be incorporated into the construct.
