FILE - In this Nov. 1, 2006 file photo, doctors replace a kidney at a public hospital in Caracas, Venezuela. Thousands of companies suffer under currency controls that all but deny them the U.S. dollars they need to import vital items into this oil-rich country, from food to cars to spare parts, even gasoline. The Venezuelan Association of Medical, Dental and Laboratory Equipment says its members collectively owe $300 million for past imports, which were suspended in November because they couldn't pay. "There are no test tubes to collect blood samples. There are no colostomy bags. No electrocardiogram paper. No X-ray plates," said Anerlin Garcia, the group's executive director.
