The choice in materials used for stenting plays a significant role in achieving increased strength especially where shape retention and surgical handling are major factors. Customized PTFE and expanded PTFE fibers are offered for use in manufacturing medical stents. Using PTFE fibers in stent fabrication provides desired properties such as natural lubricity for ease of handling, with the increased strength required for suturability and retention of shape. Applications for use of ePTFE stents center on vascular grafting. This company offers low denier ePTFE and PTFE thread available in custom lengths and widths.
