WORCESTER BUSINESS JOURNAL - Allurion said it plans to use the funding to continue growing internationally and, if it receives U.S. Food and Drug Administration approval, launch in the United States. Allurion already sells the Elipse Balloon in Europe, the Middle East, and South America. In three years, the company has sold 15,000 balloons, Allurion CEO and co-founder Shantanu Gaur said last September when Allurion moved into a new 10,000-square-foot office and lab on Erie Drive in Natick.
