Duggan was a founding shareholder of Computer Motion (now Intuitive Surgical), which develops the technology used in robot-assisted surgery, aimed at improving patients' experiences by reducing the degree of invasion during surgery. The company worked to accomplish "patient and physician-friendly" robotic surgery - a term coined by Duggan who led the company as Chairman from 1990 to 2003. On 7 Sept 2001 Computer Motion conducted the "Lindbergh Operation" - the first transatlantic telesurgical operation. It was performed by surgeons in New York on a patient in France.
