Abstract
The disclosed subject matter describes systems and methods of electrospinning a fiber for a variety of applications. An exemplary embodiment includes a medical device application for delivering a therapeutic agent, such as a sclerosing agent, to the walls of a blood vessel to perform sclerotherapy. A method of fabricating a medical balloon comprises charging a polymer material with an electric voltage, dispensing the charged polymeric material through a nozzle, collecting the charged polymeric material on a grounded mandrel, wherein the mandrel includes a tubular body having a plurality of openings extending through the tubular body, and forming an electrospun medical balloon defined by a body having a varied thickness.
