Abstract
A new manufacturing method for vascular grafts, based on a filament winding technique, is unveiled. The concept that pilots this method is presented and analysed in detail alongside the experimental results. A basic feature of filament winding is its ability to produce a two-phase structure built of a continuous fibre-reinforced polymeric matrix, shaped according to the shape of a mandrel. This structure offers a number of advantages over common vascular graft designs, e.g. better control of the mechanical properties and closer match with anisotropic properties of native arteries, and more degrees of design freedom with respect to pore size, biodegradability and biocompatibility. The experimental section offers a range of potential constituent materials, and presents an example of a Lycra fibre lPellethane matrix prototypical prosthesis.
