## Summary

Elad Einav, Co-Founder and CEO of Medibrane, a medical device CDMO specializing in polymer covers for stents, explains the engineering challenges of attaching membranes to metal scaffolds. He details the tradeoffs between traditional sewing, ePTFE sintering, and adhesive-assisted lamination, emphasizing that the covering process must be treated as a composite material design input from day one rather than a downstream manufacturing step. Einav shares examples of field failures, such as stent fractures where the covering remained intact, to illustrate why early integration of material selection, manufacturing processes, and regulatory strategy is critical for clinical success.
