In a patent infringement lawsuit involving artificial heart valves, Brattle provided consultation and market analysis. The technology in question enabled the replacement of damaged heart valves via transluminal catheter, eliminating the need for invasive open-heart surgery. Brattle’s work addressed the relationship between thoracic surgeons and interventional cardiologists in the commercialization of this technology, identified a series of medical innovations that share important characteristics with it, and discussed some of the specific advantages that the first company to bring an innovative medical device of this nature to market could expect to experience.
