History

The research that eventually led to the development of the da Vinci Surgical System was performed in the late 1980s at non-profit research institute SRI International.^[5] In 1990, SRI received funding from the National Institutes of Health. SRI developed a prototype robotic surgical system that caught the interest of the Defense Advanced Research Projects Agency (DARPA), which was interested in the system for its potential to allow surgeons to operate remotely on soldiers wounded on the battlefield.

In 1994, Dr. Frederic Moll became interested in the SRI System, as the device was known at the time. At the time, Moll was employed by Guidant. He tried to interest Guidant in backing it, to no avail. In 1995, Moll was introduced to John Freund, who had recently left Acuson Corporation. Freund negotiated an option to acquire SRI's intellectual property and incorporated a new company that he named Intuitive Surgical Devices, Inc. At that point Freund, Moll, and Robert Younge (also from Acuson) wrote the business plan for the company and raised its initial venture capital. Early investors included the Mayfield Fund, Sierra Ventures, and Morgan Stanley.{{citation needed|date=April 2014}}

The company refined the SRI System into a prototype known originally as "Lenny" (after the young Leonardo da Vinci), which was ready for testing in 1997. As the company's prototypes became more advanced, they were named using da Vinci themes. One was named "Leonardo", and another was "Mona". The final version of the prototype was nicknamed the da Vinci Surgical System, and the name stuck when the system was eventually commercialized. After further testing, Intuitive Surgical began marketing this system in Europe in 1999, while awaiting FDA approval in the United States.{{citation needed|date=April 2014}}

The company raised $46 million in an initial public offering in 2000. That same year, the FDA approved use of the da Vinci Surgical System for general laparoscopic surgery, which can be used to address gallbladder disease and gastroesophageal disease. In 2001, the FDA approved use of the system for prostate surgery. The FDA has subsequently approved the system for thoracoscopic surgery, cardiac procedures performed with adjunctive incisions, and gynecologic procedures.^[6]

Shortly before going public, Intuitive Surgical was sued for patent infringement by Computer Motion, Inc, its chief rival. Computer Motion had actually gotten into the robotic surgery field earlier than Intuitive Surgical, with its own system, the ZEUS Robotic Surgical System. Although the ZEUS system was approved in Europe, the U.S. Food and Drug Administration had not yet approved it for any procedure at the time that the FDA first approved the da Vinci system. The uncertainty created by the litigation between the companies was a drag on each company's growth. In 2003, Intuitive Surgical and Computer Motion agreed to merge, thus ending the litigation between them.^[7] The ZEUS system was ultimately phased out in favor of the da Vinci system.

Before the buyout of Computer Motion, the stock of Intuitive was selling at around $14 per share, adjusted for stock splits. After the merger, the stock price rose significantly (and by 2015 it was at about $500),^[8] primarily because of the growth in systems sold (60 in 2002 compared with 431 in 2014) and the number of surgical procedures performed (less than 1,000 in 2002 compared with 540,000 in 2014).

Finances

For the fiscal year 2017, Intuitive Surgical reported earnings of US$660 million, with an annual revenue of US$3.129 billion, an increase of 15.7% over the previous fiscal cycle. Intuitive Surgical's shares traded at over $307 per share, and its market capitalization was valued at over US$58 billion in November 2018.^[9]

da Vinci Surgical System

The da Vinci Surgical System is a robotic surgical system. The system is controlled by a surgeon from a console.

It is commonly used for prostatectomies and increasingly for cardiac valve repair and gynecologic surgical procedures.^[10][11]

Overview

The da Vinci System has been designed to improve upon conventional laparoscopy, in which the surgeon operates while standing, using hand-held, long-shafted instruments, which have no wrists. The da Vinci System consists of a surgeon's console that is typically in the same room as the patient and a patient-side cart with four interactive robotic arms controlled from the console.

Three of the arms are for tools that hold objects, act as a scalpel, scissors, bovie, or unipolar or bipolar electrocautery instruments. The fourth arm is for an endoscopic camera with two lenses that gives the surgeon full stereoscopic vision from the console. The surgeon sits at the console and looks through two eye holes at a 3-D image of the procedure, meanwhile maneuvering the arms with two hand controllers. Right sided foot controls operate the energy supplied to the instruments to cauterize, coagulate, or cut the tissue. Left sided foot controls help to move the endoscopic camera in or out and therefore bring the surgical image closer or further away. The da Vinci System scales, filters and translates the surgeon's hand movements into more precise micro-movements of the instruments, which operate through small incisions in the body.

By providing surgeons with superior visualization, enhanced dexterity, greater precision and ergonomic comfort, the da Vinci Surgical System makes it possible for more surgeons to perform minimally invasive procedures involving complex dissection or reconstruction. For the patient, a da Vinci procedure can offer all the potential benefits of a minimally invasive procedure, including less pain, less blood loss and less need for blood transfusions. Moreover, the da Vinci System can enable a shorter hospital stay, a quicker recovery and faster return to normal daily activities.^[12]

A da Vinci Surgical System costs approximately $1.5 million.^[13]

The new da Vinci SI released in April 2009 cost about $1.75 million. In addition, there are maintenance contracts plus expenditures for instruments used during surgery. Surgical procedures performed with the robot take longer than traditional ones. Critics have pointed out that hospitals have a hard time recovering the cost and that most clinical data does not support the claim of improved patient outcomes.^[11]

Efficacy

While the use of robotic surgery has become an item in the advertisement of medical services, early on critics voiced concern over the lack of studies that indicated long-term results are superior to results following laparoscopic surgery.^[14]

Lawsuit

In June 2018, Intuitive Surgical settled class action lawsuits against it for a payment of $43 million.^[15][16]
