Abstract
A process for setting in a desired shape a product at least a portion of which comprises electrostatically spun fibres is disclosed. The process comprises maintaining the product in the desired shape at a temperature below the melding temperature of the electrostatically spun fibres. The desired shape may be the as-spun shape of the product or a shape obtained by deformation of the product, i.e. the product is reshaped. The fibres preferably comprise a polyurethane and reshaping is preferably effected on a former. The reshaped product may be employed as a vascular prosthesis.
