In accordance with certain embodiments of the present disclosure a process of forming a prosthetic device is provided. The process includes forming a dispersion of polymeric nanofibers a fiberizing polymer and a solvent the dispersion having a viscosity of at least about 50 000 cPs. A tubular frame is positioned over a tubular polymeric structure. Nanofibers from the dispersion are electrospun onto the tubular frame to form a prosthetic device. The prosthetic device is heated.
