Between 1921 and 1923 she visited many clinics in Europe, including facilities in Austria, Belgium, England, France, Germany and Italy.[12] She assisted in the clinic of Marie Curie in Paris as well as in the Columbia Hospital for Women and Lying-In Asylum in Washington, DC.[8] The Faculty of Medicine of Paris awarded her the first diploma ever given to a woman for studies in urinary tract monitoring. In 1924, she designed a vaginoscope, which was much easier to sterilize and was more adaptable to multiple specula than previous models.[13] The device significantly improved services which were available to women in Brazil, and was featured in the articles of the Journal of Gynecology and Obstetrics of Rio de Janeiro. The innovation won the Grand Prize at the 1924 Congreso Hispano Lusitano Americano de Ciencias Médicas held in Seville, Spain.[14]
