Abstract
Various embodiments of a seal for a stent-valve, and methods of production, are described. In some embodiments, the seal or a skirt comprises a fabric wall portion and a polymeric material fused to the fabric wall portion, the polymeric material having a melting temperature that is lower than that of the fabric wall portion. The fibres of the fabric may remain unmelted at the interface with the polymeric material, the polymeric material being attached to material to the fibres of the fabric wall portion by fusion. The polymeric material may provide a welded joint to another fabric wall portion and/or may reinforce the fabric and/or may occlude pores of the fabric.
