Welcome to the IV Latin American Congress on Biomedical Engineering, CLAIB2007, Bioengineering solution for Latin America health. This event gathers Biomedical Engineering scientists from the Americas and other continents, presenting their latest research results. This Year CLAIB will take place on Venezuela’s Margarita Island September 24th through 28th. Margarita is “The Pearl of the Caribbean”, an ideal place to enjoy the tropical winds, famous beaches, and Venezuelan hospitality and food. Every third year, worlds and especially Latin-American bio-engineering experts gather at CLAIB to develop a shared - sion to advance human welfare, showing the products of their efforts and creativity. These multidisciplinary specialists form a synergistic team whose results contribute to the development of new technologies. This CLAIB follows the successful meetings held in Joao Pessoa (Brazil, 2004), Habana (Cuba, 2001) and Mazatlán (Mexico, 1998). CLAIB is sponsored primarily by the Regional Council of Biomedical Engineering for Latin America (CORAL), and the International Federation for Medical and Biological Engineering (IFMBE). We will make every effort to make CLAIB 2007 a memorable event and that each participant will contribute to a CLAIB full of good experiences and memories. We look forward to meeting you all in Margarita Island. Professor Carmen Müller-Karger Representing the Organizing Committee President of the Scientific Committee CLAIB2007
