Control of weft yarn or density improves biocompatibility of PET small diameter artificial blood vessels

Polyethylene glycol terephthalate (PET) fabrics with woven structures have proved to be quite effective for use on large diameter artificial blood vessels. However, their use within small‐diameter artificial blood vessels has been associated with poor long‐term patency, a problem resulting from slow endothelialization on PET and an over hyperplasia of smooth muscle cells. Previous research from our laboratory has revealed that ICAM‐1 can be used...
