RBC Capital analyst Brandon Henry noted that the FDA issued a safety communication regarding the use of robotics in cancer-related women's health surgeries, which he believes could put some incremental pressure on part of Intuitive Surgical's U.S. business with gynecologists, particularly the cancer-related hysterectomy portion. While he said the potential impact should be manageable, Henry thinks it is prudent to model a decline in Intuitive's U.S. cancer-related hysterectomies business in 2019, the analyst stated. He maintains a Sector Perform rating on Intuitive Surgical shares.
