Thank you, Marshall. During the third quarter, we sold 133 da Vinci Systems: 99 in the United States, 18 into Europe and 16 into rest of world markets. As part of the 133 system sales, 14 standard da Vinci Systems and 21 da Vinci S Systems were traded in for credit against sales for new da Vinci Si Systems. We had a net 98 system additions to the installed base during the quarter, which brings to 2,031, the cumulative number of da Vinci Systems worldwide: 1,478 in the U.S., 357 in Europe and 196 in rest of world markets. 60 of the 133 systems installed during the quarter represented repeat system sales to existing customers. In total, 117 of the 133 systems sold represented da Vinci Si Systems, which included 29 dual console systems. The 34 system sales internationally included 6 da Vinci Systems into Japan, 6 into Germany, 4 into India and 3 into Spain. Clinically, we had a strong quarter, achieving overall year-over-year procedure growth of approximately 30%. Colorectal and thoracic surgery growth was particularly strong, while gynecology displayed solid sequential growth, specifically, benign hysterectomy and myomectomy. As mentioned in the past, Q3 represents certain seasonal challenges specifically in Europe. The months of July and August are particularly slow. Our European system sales growth for the quarter was less affected than our EU procedure business during these months. Our systems sales performance in Europe continues to be fueled by urology. Q3 represents a quieter quarter for clinical trade shows and surgical conferences. However, it represented a very productive quarter for clinical publications within the medical journal. This quarter alone, nearly 400 papers and abstracts appeared within various peer-reviewed journals. Gynecology, urology, general and colorectal, head/neck, cardiac and thoracic surgery were well represented. The British Journal of Urology, which is considered to be among the more conservative and most respected peer-reviewed urology journals in circulation, dedicated their entire September edition to papers reporting on da Vinci's role within their field. The edition contained 15 papers covering a wide range of da Vinci studies, including dVP, da Vinci Nephrectomy, da Vinci Cystectomy and da Vinci Pyeloplasty. In addition to the market clinical reports in comparisons, there were also procedure technique and economic cost reviews. A few reports offered neutral or even clinical analysis of robotic surgery, but the majority were positive. Rather than taking time to review each of these papers in detail, I'll take a moment to highlight some of the written observations and conclusions. With regard to da Vinci Cystectomy, Dr. Lee and his team from Cornell concluded that despite an increased materials cost, robotic radical cystectomy can be more cost-efficient than open radical cystectomy as a treatment for bladder cancer when the impact of complications is considered. With respect to da Vinci Partial Nephrectomy, Doctors Abreu and Gill from USC reported that within their study, 0 ischemia robotic partial nephrectomy was successful in all cases without any higher eclamping and the warm ischemia time was 0 in all cases. They also stated that the elimination of warm ischemia may ultimately preserve renal function. Doctors Cha and Lee wrote, "Robotic partial nephrectomy appears to be a viable minimally invasive option for nephron-sparing surgery. Robotic partial nephrectomy may reduce some of the technical challenges associated with lap partial nephrectomy, and thus, extend the potential benefits of minimally invasive nephron-sparing surgery to a larger population." [Audio Gap], simply, that da Vinci has become an integral tool in urologic cancer surgery, and its presence in the global urologic community has become widespread. The dedication of an entire British Journal of Urology edition to robotic surgery is just further evidence of this phenomenon. A very large observational study comprised of over 19,000 prostate cancer surgery patients appeared in the British Journal of Urology a month earlier. The study analyzed the substitution that took place between open prostatectomy and minimally invasive prostatectomy over a 4-year period beginning in 2003. These patients had their prostatectomy between 2003 and 2006. However, the reported trends should certainly apply to subsequent years. The study emanated out of Brigham and Women's Hospital in Boston and was a collaboration between the Division of Urology and the Center for Surgery and Public Health. The aim of the study was to determine differences in surgical outcomes by surgical approach during a period of rapid adoption for the minimally invasive surgical approach to radical prostatectomy. The study noted that minimally invasive radical prostatectomy had grown from 5.7% of the U.S. prostatectomies in 2003 to approximately 39.2% in 2006. At the same time, open prostatectomy decreased by approximately 33.5%. During this study period, the length of hospital stay for minimally invasive radical prostatectomy decreased from 2 days to 1 day, and the length of stay for [Audio Gap] 3.2 days to 2.9 days. The perioperative complication rate for minimally invasive radical prostatectomy had decreased from 13.8% to 10.7% while at the perioperative complication rate for open prostatectomy had decreased from 18.1% to 14.6%. Said another way, the perioperative complication rate for minimally invasive radical prostatectomy at the end of 2006 was 27% less than it was for open prostatectomy. When comparing the data over the entire 4-year study period, the results were fairly striking. Perioperative complications were 27% less for the minimally invasive group. Blood transfusions were fewer by 83%. Anastomotic strictures were fewer by 51%, and length of stay was shorter by 42%. In their conclusions, the authors stated, and I quote, "The increased use of minimally invasive radical prostatectomy corresponds with a decreasing trend for complications, blood transfusions, length of stay and need for reoperation. Additionally, minimally invasive radical prostatectomy was found to have fewer associated complications compared with men undergoing the open procedure." As we've mentioned in previous calls, da Vinci's role within the specialty of thoracic surgery is on the rise. The desire to reduce or eliminate large, painful intercostal incisions is shared mutually by patients and surgeons. Traditional video-assisted thoracoscopy has provided some relief for patients. However, its adoption has been somewhat limited to smaller, less complex procedures. While da Vinci Lobectomy, wedged and segmental procedures, are relatively new, with instrument sets that have yet to be optimized, it's early adoption has been strong. In a recent edition of the Journal of Thoracic and Cardiovascular Surgery, Dr. Robert Cerfolio and his team from the University of Alabama, Birmingham published a study on their initial 168 consecutive completely portal robotic pulmonary resections. The study took place over a 14-month period and included lobectomies, wedge and segmental resections. The majority, 106 patients, had da Vinci Lobectomies. The results of the da Vinci patients were compared to 318 propensity-matched patients who underwent a rib and nerve-sparing thoracotomy. The metrics that made up the comparison were morbidity, mortality, quality of life, hospitalization and operative time. Dr. Cerfolio reported that the da Vinci group had a morbidity rate of 27% compared to a 38% morbidity rate for the thoracotomy group. Associated mortality was 0 for the da Vinci group and 3.1% for the thoracotomy group. Quality-of-life metrics were defined as the subject's functioning and well-being in the physical, psychological and social domains in relation to their disease and treatment. In this comparison, the da Vinci group scored 53 compared to 40 with the thoracotomy group. Hospitalization was reduced in half, 4 days to 2, when performing these procedures robotically. And finally, technical procedure improvements in their final 106 patients, which included fourth arm retraction and some minor instrument modification, only one was converted to an open thoracotomy. All patients underwent a lymph node dissection, which yielded an average of 17 lymph nodes. As is usually the case with initial series comparisons, the procedure time for the robotics patients was shown to be a bit longer than with the open thoracotomy group. In conclusion, the author states, and I quote, "The newly refined 4-arm robotic lobectomy is safe and yields an R0 resection with complete lymph node removal. It has a lower morbidity, mortality, shorter hospital stay and better quality of life than rib and nerve-sparing thoracotomy. Technical advances are possible to shorten and improve the operation." As many of you have recently read, the U.S. Preventive Services Task Force has published its recommendations against PSA screening for prostate cancer. Their recommendation applies to U.S. men that do not have symptoms that are considered highly suspicious for prostate cancer, regardless of age, race or family history. You may also be aware that the American Urology Association disagrees with the panel's recommendation. Our position on this topic is consistent with the 18,000 physicians that comprise the AUA. It is our belief that the physician members of the AUA are in the best position to appropriately assess the tools and techniques for screening their patients for this serious disease. This concludes my remarks. And I'll turn the time over to Calvin.
