Thank you, Marshall. During the first quarter, we sold 120 da Vinci Systems, 89 in the United States, 15 in Europe and 16 in rest of the world markets. As part of the 120 system sales, 13 standard da Vinci Systems were traded in for credit against sales for new da Vinci Si Systems and 19 S systems were traded in for Si Systems. We had a net 88 system additions to the installed base during the quarter, which brings to 1,840, the cumulative number of da Vinci Systems worldwide, 1,344 in the U.S., 330 in Europe and 166 in rest of world markets. 51 of the 120 systems installed represented repeat system sales to existing customers. In total, 110 of the 120 systems sold during the quarter represented da Vinci Si Systems, which included 15 dual console systems. The 31 system sales internationally included five da Vinci systems into Japan, four into Australia and three into the countries of Germany, France and Turkey. Clinically, we had a solid quarter, achieving overall year-over-year procedure growth of approximately 30%. Neurology and thoracic showed particularly solid sequential strength. On a year-over-year basis, the categories of thoracic, head and neck, GYN, colorectal and general surgery displayed the strongest growth. As we previously discussed, Q1 is a seasonally challenged quarter for surgeries that could be classified as discretionary, which causes some early year lumpiness within benign gynecologic procedures. Consistent with Q1 2010 procedure trends, malignant dVH showed greater sequential strength than benign dVH during the quarter. However, on a year-over-year basis, benign dVH is growing at a faster rate than malignant dVH. The overall category of da Vinci GYN surgery grew approximately 40% on a year-over-year basis. We would expect to see normal dVH cycles resume for the remainder of the year. Within urology, our dVP business remains strong and particularly so outside the United States, specifically within Europe. France and Germany are coming up the curb nicely, and Italy remains strong. We described our U.S. dVP business as relatively flat over the past several quarters. However, on a sequential basis, it can fluctuate a bit, and in Q1, it showed sequential strength. Having said that, we believe the greatest opportunity for growth will continue to be fueled from the OUS markets. At last year's European Association of Urology Conference, da Vinci related presentations, abstracts and postgraduate courses dominated the agenda, and the live surgery presentations were projected into standing-room only audiences. And at next month's AUA Conference, over 200 da Vinci-related abstracts have already been accepted. In addition, 16 AUA postgraduate courses will include da Vinci. dVP growth and urology in general remains strong and is certainly a catalyst for many of our OUS system placements. Regarding Japan, as you can imagine, the catastrophic earthquake and subsequent tsunami have caused significant disruptions to the healthcare system and has placed a tremendous burden on all Japanese government resources. The five da Vinci sales in Japan had occurred prior to these tragic events. We would expect uncertainty within Japan to prevail for some time to come and we will share more as it becomes known. During the quarter, over 200 clinical papers were presented at various conferences and/or within peer review journals. But I'll take a moment to highlight just a few. In the recent edition of the journal Gynecologic Oncology, Doctors Lim and Kang et al, published a paper entitled a Comparative Detailed Analysis of the Learning Curve and Surgical Outcome for Robotic Hysterectomy with Lymphadenectomy versus Laparoscopic Hysterectomy with Lymphadenectomy in Treatment of Endometrial Cancer: A Case-Matched Controlled Study of the first 122 Patients. The goal was to determine the learning curve and surgical outcome for the first 122 robotic hysterectomy with lymphadenectomy patients in comparison to the first 122 patients who underwent the same procedure laparoscopically. The learning curve of the surgical procedure was determined by measuring operative time with respect to chronological order of each patient who had undergone their respective procedure. Number of lymph nodes, estimated blood loss, days of hospitalization and complications of all patients were also analyzed and compared. Data were analyzed by mean age, body mass index, operative time, estimated blood loss, lymph node retrieval and complications for both surgical procedures. In their results, they reported the mean operated time was approximately 40 minutes shorter for the dVH cohort as compared to the traditional laparoscopic cohort. The mean estimated blood loss was statistically significant at 81 milliliters for da Vinci hysterectomy compared to 207 milliliters for the laparoscopic approach. The days of hospitalization for the dVH patients was 1.5 days compared to 3.2 days for the laparoscopic group. The number of intraoperative complications in the dVH group was one as compared to seven within the lap group. The authors concluded by saying, and I quote, "Robotic hysterectomy with lymphadenectomy has a faster learning curve in comparison to laparoscopic hysterectomy with lymphadenectomy. The adequacy of the surgical staging was comparable between the two surgical methods. Robotic hysterectomy is associated with shorter hospitalization, less blood loss and less intraoperative and major complications, and lower rate of conversion to open procedure." The interest in da Vinci from the thoracic community is increasing rapidly. In addition to lobectomies, we're seeing interest in thoracic pull-through procedures such as mediastinal mass resections. While the procedure numbers may be relatively small, the patient value is potentially very high. In a recent edition of the European Journal of Cardio-thoracic Surgery, a paper out of the University of Antwerp in Belgium authored by Doctors Balduyck and Hendriks et al entitled, Quality of Life After Anterior Mediastinal Mass Resection: A Prospective Study Comparing Open with Robotic-Assisted Thoracoscopic Resection, was published. The objective was to prospectively evaluate quality of life evolution after robotic-assisted thoracoscopic resection as compared to open anterior mediastinal tumor resection. The authors used a validated European quality of life questionnaire. Quality of life was prospect of all patients undergoing surgery for mediastinal tumors. A total of 36 patients underwent thoracoscopic resection using either the da Vinci robotic system or a sternotomy-based open resection. Questionnaires were administered before surgery and at one, three, six and 12 months, postoperatively, with response rates of 100%, 86%, 94% and 75% respectively. The results were as follows: Both approaches had comparable preoperative patient characteristics and quality of life subscales. Open resection by sternotomy was characterized by a significant decrease in general functioning one month after surgery, both physical and social. Patients also complained of increased thoracic pain in the first three months post-surgery. Following a da Vinci robotic resection, quality of life scores approximated the baseline preoperative scores one month after surgery. In other words, there were no reduction in patient function scores at the first postoperative quality of life measurement. The authors' conclusion, and I quote, "Numerous techniques have been published with different degrees of invasiveness, generating the existing controversy as to which is the best surgical approach for anterior mediastinal tumors. The high burden of decreased physical functioning reported after sternotomy is not seen after the da Vinci robotic-assisted thoracoscopic resection. The initial experience and postoperative quality of life data are excellent and, therefore, the da Vinci robot will stay our future technique of choice for the treatment of resectable mediastinal tumors measuring less than 4 centimeters." The patient value of replacing large thoracotomies and/or sternotomies with a small, minimally invasive incision is significant, which is one of the reasons why thoracic surgery has become one of our fastest-growing specialties. In closing, I'll remind you that the second quarter marks the peak of our busy global conference season, with the AUA, ACOG, AATS and the American Society of Colorectal Surgery Conference is taking place, to name a few. We will provide you with the clinical highlights from some of these conferences during next quarter's call. That concludes my remarks, so I'll turn the time over the Calvin.
