In the first use of these catheters in humans, each catheter was specifically shaped to match the size and shape of the aorta of the subject. His work was documented in 1967, and by 1968 the Judkins catheters were manufactured in a limited number of fixed tip shapes.
Cut of beef. Cuts of beef are first divided into primal cuts, pieces of meat initially separated from the carcass during butchering. These are basic sections from which steaks and other subdivisions are cut. The term primal cut is quite different from prime cut, used to characterize cuts considered to be of higher quality.
Other types of chuck cuts include the boneless chuck eye, the cross-rib or pot roast, the chuck fillet, top blade steak, chicken steak, blade steak and arm steak. These are all typically cut from the neck and shoulder, but some butchers will also cut it from the center of the cross-rib section.
