Thank you, Marshall. During the second quarter, we sold 150 da Vinci systems: 124 in the United States, 13 into Europe and 13 into rest of world markets. As part of the 150 system sales, 12 standard da Vinci systems and 23 da Vinci S Systems were traded in for credit against sales for new da Vinci Si Systems. We had a net 115 system additions to the installed base during the quarter, which brings to 2,341 the cumulative number of da Vinci Systems worldwide: 1,707 in the U.S., 389 in Europe and 245 in rest of world markets. 79 of the 150 systems installed during the quarter represented repeat system sales to existing customers. In total, 142 of the 150 systems sold represented da Vinci Si Systems, which included 28 dual console systems. The 26 system sales internationally included 7 into Japan, 4 into France and 3 into the U.K. Clinically, we had a solid quarter, achieving year-over-year procedure growth of approximately 26%. Gynecology, general surgery, along with the emerging categories of thoracic and head and neck surgery, accounted for a large part of this growth. Da Vinci Hysterectomy, Cholecystectomy, Colon and Rectal Resections, Lobectomy, Endometriosis Resections, Myomectomy and Partial Nephrectomy exhibited strong quarter-over-quarter growth, which was partially offset by dVP softness in the United States. The recent pressure from nonsurgical disease management, namely active surveillance, as well as an apparent decline in PSA screening has caused some pull back in the U.S. dVP number. As the incumbent leader in the surgical treatment of prostate cancer, it's difficult, perhaps impossible to remain unaffected by this larger trend, at least in the short term. Recently released new products continue to do well, most notably Single-Site. Early customer feedback has been positive and our initial sales have been strong. Within the first 2 quarters, post-launch, we've sold Single-Site kits to over 200 U.S. customers, while demand for training remains strong. We initiated our phased rollout of the vessel sealer product in February and its use within the segments of general, colorectal and GYN surgery has begun. The product is performing well and the feature set, specifically the articulated risk design, appears to be satisfying a strong market need. Operationally, we continue to make progress toward optimizing the manufacturing process while reducing product costs. Regarding system attachments, namely da Vinci Simulator and da Vinci Firefly. Both attachment rates remained high in the second quarter. Strong market acceptance for these products has helped buoy our da Vinci system ASP to an all-time high. During the quarter, over 350 robotic abstracts and papers representing a variety of surgical specialties were published within various peer-reviewed journals, and the clinical conferences were abundant with live da Vinci procedure transmissions, postgraduate robotic courses and podium presentations and clinical poster sessions. The adoption of our international dVH business has lagged behind the United States for both malignant and benign conditions, not surprising. We believe that dVH for the treatment of malignant conditions will likely pace the international GYN business. In a recent edition of the International Journal of Gynecologic Cancer, doctors Mark and Yang [ph] from the National University in Singapore, published a study describing the conversion of their open hysterectomy practice to a da Vinci Hysterectomy practice in treating endometrial cancer. Open surgery is the standard of care for endometrial cancer staging in Singapore, as it is in many other countries. This study compared the results of open hysterectomy to dVH in 124 consecutive endometrial cancer patients. The patients in each cohort were of similar age, BMI and pre-existing health condition. The authors reported that their operating time was longer during their initial 20 dVH procedures but had dropped significantly thereafter and were subsequently on par with the comparator. Lymph node harvests were also slightly lower within the initial 20 cases, but were similar thereafter. However, dVH was associated with 56% less blood loss than open surgery; had a lower rate of postoperative complications, 8.8% versus 26.8%; and a lower wound complication rate, 0% versus 9.9%. In addition, the requirement for postoperative parenteral analgesia was only 5.9% for the dVH patients as compared with 51.1% for the open laparotomy patients. And hospitalization was reduced to 2 days for the dVH patients as compared to 5.9 days for the open laparotomy group. They concluded their paper by stating and I quote, "Our series shows that outcomes traditionally associated with laparoscopic endometrial cancer staging are achievable by laparoscopically naive gynecologic cancer surgeons moving from laparotomy to robotic-assisted endometrial cancer staging after a relatively small number of cases." Early data for da Vinci Single-Sites choles is being collected at various sites within the U.S. and abroad, while the initial EU publications begin to appear in the literature. In a recent edition of the Archives of Surgery, a consortium made up of 5 leading Italian robotic centers published initial results of their first 100 Single-Site cholecystectomy procedures. The paper entitled Overcoming the Challenges of Single Incision Cholecystectomy with Robotic Single-Site Technology, described the contribution of traditional single incision laparoscopy as an important development step in moving from multiple site laparoscopy to single incision interventions. However, single incision laparoscopic cholecystectomies has not gained wide spread use due in large part to the physical limitations of the technology, which compromises optimal triangulation, the overall ergonomics of the procedure and quality of view, this, according to the authors. They also reported that the combination of these factors provides challenges for optimal tissue exposure and that traditional instruments platforms have significant limitation when used for SILS. They went on to say and I quote, "Da Vinci Single-Site Cholecystectomy was regarded as a safe procedure by all surgeons involved in this study and as safe as standard four-port laparoscopic operation." They also reported that 4 out of the 5 surgeons participating in this trial claimed to be considering the extension of da Vinci Single-Site Technology toward treating other conditions. In their conclusion, they wrote and I quote, "The robotic technology is a compensatory technique that can overcome the constraints and the ergonomic limitations of SILS and is potentially capable of realizing the full potential of single-access approach. We showed that it allows for the quick overcoming of the learning curve that is typical to most new procedures, particularly of laparoscopic single incision approach. This is likely to increase the safety of single-incision surgery, and in turn, expand adoption to a wider number of general surgeons and surgical procedures." In a recent edition of the British Journal of Urology, an interesting paper out of Asia authored by Dr. Shin Dong Chung [ph] and others from National University Hospital in Taiwan studied the readmission rates for patients who have undergone open prostatectomy, lap prostatectomy and robotic prostatectomy. The nationwide Taiwanese study included 2,741 patients, studied over a 5-year period with the objective of determining the sub 90-day readmission rate associated with each of the 3 techniques. The reduction of readmission rates is a goal shared by all economies since the associated costs can be quite significant for payers and patients. In total, 257 or 9.4% of the 2,741 patients studied required a readmission to a hospital within 90 days post surgery. The diagnosis for readmission included intestinal infections, UTIs, hernias, pneumonia, prostatic hypertrophy, retention of urine and postoperative infection. The authors reported that the readmission rate for traditional laparoscopic prostatectomy patients was more than twice as common than for patients undergoing a dVP. 8.2% for lap versus 3.6% for dVP. When comparing the readmission rate for open prostatectomy to dVP, the frequency of readmission was nearly 3x as great, 10.7% versus 3.6%. In a written discussion, the author stated and I quote, "In the present study, we clearly showed that patients undergoing robotic-assisted laparoscopic prostatectomy had a lower risk of 90-day readmission than the patients undergoing open prostatectomy. We think that the present study is an important step in helping to define the relative efficacy of robotic prostatectomy, laparoscopic prostatectomy and open prostatectomy as a treatment option for localized prostate cancer. Moreover, the present findings may prove valuable to patients trying to make an objective decision about the various treatment options. Because the present study used nationwide population-based data sets, its robust findings can be generalized to a population as a whole." This concludes my remarks. And I'll now turn the time over to Calvin.
