Using image guidance, a catheter is inserted through the skin into a large vein in the neck or upper leg and advanced to the inferior vena cava in the abdomen. The IVC filter is then placed through the catheter and into the vein.
The Munich Agreement was the agreement signed on 29 Sept 1938 between Chamberlain, Daladier (France), Hitler and Mussolini (Italy). There is a whole section on the website on the Sudeten crisis, which led up to the agreement, on http://www.johndclare.net/RoadtoWWII5.htm.
Although it was not actually signed until 1 am on 30 Sept, the Munich Agreement was dated 29 Sept. It promised that the Czech army would pull back from the German areas of Czechoslovakia by 10 October. On the surface, it was NOT a total climbdown.
