A tissue compression cuff comprises a first fastening portion defining one or more openings and at least one band. The at least one band comprises a first end extending from the first fastening portion at a first end, and an opposing second end, the at least one band defining a first diameter at the first end and a second diameter at the second end. The first diameter is larger than the second diameter. A second fastening portion is positioned at the opposing second end of the at least one band. The second end of the at least one band is configured to be inserted through the one or more openings of the first fastening portion. The tissue compression cuff is sized and configured to reduce blood flow through an arteriovenous fistula and made from an electrospun textile made up of biocompatible nanofibers.

Tuning surface properties of melt blown polyester fibers by hydrolysis and solution grafting

Described herein is a continuous process for modifying the properties of polyester and polyester based fibers, such as a poly(butylene terephthalate) (PBT) fiber, comprising subjecting the PBT fiber to alkaline hydrolysis, and optionally further comprising functionalizing the PBT fiber by solution grafting such as fluorination. The alkaline hydrolysis and optionally subsequent functionalization such as fluorination process can be continuous, following the melt blowing/spinning or spun-bonding process. Also described is a nonwoven PBT fiber mat obtained by the surface modification process. Further described is a filtration device comprising the nonwoven PBT fiber mat.
