The First Bifurcated Aortal Graft – In the late 1950s, Dr. Thomas Edman ’48, alumnus and then-chairman of the knitting department, and his staff at the University worked with Dr. Michael DeBakey, a pioneer cardiologist at Baylor University, to develop a machine that would produce multi-branched seamless tubes that could knit fibers into blood vessels needed for artificial blood vessels called vascular grafts. The team designed a machine that could be produced for $25,000.
