Gary Guthart, president and CEO of Intuitive Surgical, said in the company's Oct. 18 earnings release that he is pleased with the strong third-quarter procedure growth and da Vinci system placements. Worldwide, da Vinci procedures grew about 20% compared to the third quarter of 2017, based on growth in U.S. general surgery procedures and worldwide urologic procedures. Instrument and accessories revenue increased year over year about 21% to $486 million, compared to $401 million in 2017, stemming from an increase in da Vinci procedure volume. Sunnyvale, Calif.-based Intuitive Surgical shipped 231 da Vinci surgical systems during the quarter, an increase from 169 in the same period in 2017.

Intuitive Surgical ended the third quarter with $4.6 billion in cash, cash equivalents and investments, recording a $311 million increase during the quarter, driven mainly through cash generated from operations.
