Warp knitted carotid patch having finished selvedged edges

摘要

A warp knitted vascular patch material, made in specific widths, the selvedges of the material are specially finished on the knitting machine without the introduction of additional threads to give a strong edge which will not fray and give firm support for the sutures. The specially knitted edges enables small neat sutures to be made without the risk of pulling out. This prevents all the problems of fraying edges and bulky seams found when unsized material is cut to the required width. This patch material is designed specifically for arterial closure following a carotid endorectomy.
