The 11th annual Cleveland Clinic Medical Innovation Summit, which wrapped up this past Wednesday at the newly opened Global Center for Healthcare Innovation in the city's downtown, was no exception. Peter Orszag, PhD, vice chairman of corporate and investment banking at Citigroup, discussed the relationship between medical innovation and efforts to control healthcare cost increases during a lunchtime presentation on Tuesday. Orszag's talk was closely followed by a panel of industry and venture capital experts who offered their take on the best investment opportunities in the metabolic disorders marketplace.
