Thank you, Marshall. During the second quarter, we sold 129 da Vinci systems, 99 in the United States, 16 in Europe and 14 in the rest of world markets. As part of the 129 system sales, 15 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 93 system additions to the installed base during the quarter, which brings to 1,933 the cumulative number da Vinci systems worldwide. 1,411 in the United States, 342 in Europe and 180 in the rest of world markets. 62 of the 129 systems installed represented repeat system sales to existing customers. In total, 121 of the 129 systems sold during the quarter represented da Vinci Si Systems, which included 21 dual console systems. The 30 system sales internationally included 4 da Vinci systems into Japan, 4 into Italy and 3 into both Switzerland and India. Clinically, we had a strong quarter, achieving overall year-over-year growth of approximately 30%. Gynecology in the United States was particularly strong, while growth within general surgery, urology, thoracic and head-neck procedures was solid. As mentioned in the past, Q1 is a seasonally challenged quarter for surgeries that could be classified as discretionary, which causes some early lumpiness within benign gynecologic procedures. Consistent with Q2 2010 procedure trends, benign dVH growth during the second quarter of 2011 grew solidly faster than malignant dVH. In addition to strong dVH adoption, sacrocolpopexy, endometrial resection, myomectomy have been key factors to the U.S. GYN expansion. In Europe, dVH growth has begun to emerge within malignant procedures, primarily endometrial and cervical cancer resection. In addition, the category of general surgery has shown signs of early adoption. However, most of our EU growth is still being fueled by urology. In Asia, urology and general surgery were the strongest categories through the first half of the year. All in all, Q2 procedure growth showed global strength across several key categories. Q2 represents our busiest quarter for clinical trade shows and surgical conferences. The volume of clinical data presented, procedure technique reviews and live surgery presentations was impressive. AUA represented 200 or so abstracts and 16 postgraduate courses. WRS was packed with live surgery, robotic panels and podium discussions covering all segments of surgery. Not to mention SAGES, the American Society of Colorectal Surgery, AATS and ACOG, as well as the various international conferences we participated in. We are convinced that the dissemination of peer-reviewed clinical data has been a critical factor in the rapid adoption of da Vinci surgery. And the peer-review exposure we received at these important venues is immeasurable. During the quarter, over 200 clinical papers were published within various peer-review journals representing all of our targeted specialties, but I'll take a moment to highlight just a few, which I believe represent an important theme. The economic impact of reduced complications and hospitalization and their connection toward improving clinical outcomes. In years past, providers would report on the cost effectiveness of robotic surgery in a fairly simple and consistent manner, whereby they consider the purchase price of the capital equipment add to it their operating costs and divide it by the number procedures they've completed. Direct cost comparisons were usually made to open a laparoscopic surgery. However, the cost of hospitalization and the cost of complications were often omitted. Recent published studies have included broader analysis that includes both direct and indirect hospital costs. In a recent edition of the Journal of Obstetrics and Gynecology, a team from Brigham Women's Hospital and Harvard Medical School, comprised of both physician and business professionals, studied and reported on the evolution of the hospitals hysterectomy business in 2006 and compared it to 2009. Specifically, they study how the shift from open and vaginal hysterectomy to laparoscopic and robotic hysterectomy had affected their costs. The paper entitled Increasing Minimally Invasive Hysterectomy, the effects on cost and complications evaluated the overall costs associated with 2,133 hysterectomy patients that underwent the procedure in 2006 and 2009. This study reported and I quote, "A change from majority abdominal hysterectomy to minimally invasive hysterectomy was accompanied by a significant decrease in procedure related complications without an increase in total mean cost." Some of the relevant details. In 2006, approximately 65% of the 1,054 hysterectomies performed at Brigham and Women's were performed abdominally. In 2009, only 35% out of 1,079 were performed abdominally. Lap and robotic approaches comprised 17% of the hysterectomies in 2006, which grew to 46% in 2009. Vaginal hysterectomy remain fairly stable during this period and was typically confined to less complex cases. When evaluating outcomes and costs, the results were quite striking. The deviates cohort was associated with the lowest intraoperative and postoperative complication rates and the lowest estimated blood loss across all cohorts and along with laparoscopy, registered the lowest length of stay data in the group. The differences were considered very significant. When comparing abdominal hysterectomy to dVH, length of stay was reduced from 3.5 days to 1.4 days, estimated blood loss went from 363 millimeters to 75 milliliters. The most telling was the reported complication rate. The rate of major intraoperative and postoperative complications associated with abdominal hysterectomy was shown to be approximately 5x greater than with dVH. To quote the authors, "Our data suggest that dedication to the implementation of a minimally invasive technique goals, such as a decreased complications, decreased operative times, decreased conversion rate and decreased estimated blood loss can be realized. A creation of a minimally invasive gynecology service at Brigham and Women's Hospital has benefited not only the trainees and the hospital but first and foremost our patients." In the June edition of the American Journal of Obstetrics & Gynecology, a study out of Seattle authored by Doctors Paley, Veljovich and Shah entitled Surgical outcomes in gynecologic oncology in the era of surgical robotics: an analysis of the first 1,000 cases was published. This study was very comprehensive and it reported on multiple factors and clinical outcomes related to da Vinci cancer surgery. There were, however, 2 comparisons that were central in this paper. First, could the authors increase the complexity of their da Vinci patients without increasing the complication rates? And second, how did their dVH outcomes for endometrial cancer resection compare to open hysterectomy outcomes? The second objective would consist of a subset analysis of their most recent 377 da Vinci Hysterectomies and Endometrial Resection compared to the most recent endometrial resection, open endometrial resection surgeries. From 2006 to 2009, deviate share at the institution had grown from 9% to 36% of the GYN cancer resections. But further penetration was being governed by their unwillingness to accept higher BMI patients at the risk of increasing their complication rates, a concern, which was dispelled by their careful analysis. During the study period, the physicians raised their BMI constraints at 3 intervals, beginning at 26 until reaching at an average BMI of just over 30. Within their first interval, they operated on patient -- excuse me, within their final interval, they operated on patients with BMIs as high as 70. Interestingly, they discovered that neither their conversion rate nor complication rates increased within these more complex cohorts. In fact, they actually decreased. Their overall conversion rate for their entire 1,000 patient analysis was a mere 2.9% and their overall complication rate was 9.9%. 5.7% for majors and 4.2% for minor complications. In a subset analysis of women undergoing endometrial cancer resection, the difference between dVH and open hysterectomy was significant. Major complications associated with open surgery was 20.6%, as compared to 6.4% for dVH. In patients with BMI in excess of 40, major complications dropped from 43.5% for open to 11.3% for dVH. Length of hospitalization was reduced from 5.3 days for open to 1.4 days with dVH. Lymphnode yields were approximately 10% higher within the dVH group. Intensive care unit admissions went from 3.8% for open to 0.5% for dVH. Mortality rates dropped from 1.5% to 0.27%. Their conclusion, and I quote: "Robotic surgery is associated with favorable morbidity and conversion rates in an unselected cohort. Compared to laparotomy, robotic endometrial cancer surgery results in improved outcomes." In a recent edition of the British Journal of Urology, a physician group out of Cornell and Presbyterian Hospital, New York City published their study comparing the overall cost associated with open cystectomy, lymph node dissection and diversions to da Vinci Cystectomy with diversions. This prospective study consisted of 186 consecutive patients and included appropriate sensitivity analysis. The authors collected a myriad of cost data, both direct and indirect and these costs were carefully analyzed. Cost data included, but was not limited to, system and service amortization, disposables, length of stay, complications, surgeon fees and anesthesia cost. In other words, both direct and variable costs were collected and scrutinized. Their study contained 3 approaches to urinary diversion following cystectomy. With the ileal conduit approach being the most commonly performed and the largest subcategory study. Not surprisingly, the authors concluded that the greatest contribution to cost variation between the various cohorts were length of stay and complications. Across the board, the direct cost between the various cohorts was pretty similar plus/minus $1,000 or so. But the difference in variable cost was very significant, in da Vinci's favor. In an overall cost basis, comparing open cystectomy with ileal conduit to a da Vinci cystectomy with ileal conduit, it was reported that the da Vinci Cystectomy saved nearly $5,000 over the open surgical approach. The cost difference between the other 2 diversion techniques was less pronounced, slightly in da Vinci's favor for the continent, cutaneous diversion and slightly in the favor of the open technique for the orthotopic neobladder approach. The least common approach. The authors' conclusion, "Despite the higher cost of materials, robotic cystectomy can be more cost-efficient than open cystectomy for bladder cancers at high-volume tertiary referral center, particularly for ileal conduit." The reduction in hospitalization, blood loss, complications and overall hospital cost has been a consistent theme throughout Intuitive's short history. They are central components in our pursuit to improve patient value. That concludes my remarks. And I'll now turn the panel to Calvin.
