Abstract

A system for electrospinning a fiber matrix on a tubular member includes at least one nozzle, a tubular member in a spaced relationship to the at least one nozzle, and a fluid source for pressurizing a lumen of the tubular member. An electrical potential is applied between the at least one nozzle and either the tubular member or fluid from the fluid source. The electrical potential draws at least one fiber from the at least one nozzle to the tubular member.
