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.
The cut is also called a top blade steak, in a reference to the region of the cow that it comes from. The steak is cut from the area just behind the shoulder of a cow. Traditionally, the large cut of meat from this region has been called a blade roast.
