Document Summary

Osteolysis: degradation of bone tissue, usually the result of an inflammatory process, can be triggered by wear particles. Aneurysm: ballooning in a blood vessel due to localized weakness in the vessel wall, can lead to rupture of the vessel. Hydrophobic: water hating surface, one with a surface tension that causes water to bead up rather than spread on the material. Tunica media: the middle layer of an artery, composed primarily of smooth muscle cells. Neointimal hyperplasia: tissue overgrowth that occurs in the wall of an artery when endothelial cell damage stimulates smooth muscle cell proliferation and migration within the intimal layer and towards the lumen of the vessel. Endothelial cells: the cells that line the blood-contacting surface of vessels. Woven dacron: fabric used in vascular graft applications and formed by weaving yarns of polyethylene terephthalate. Suture retention : the degree to which sutures are held in place at the junction of a vascular graft and a native blood vessel.
