Thank you, Marshall. During the third quarter, we sold 91 da Vinci systems, 71 in the United States, 12 in Europe and eight into rest of world markets. A total of five system sales were part of trade-off transactions. The net 86 new installations brings to 1032, the cumulative number of da Vinci systems worldwide, 776 in the United States, 171 in Europe and 85 in rest of world markets. 15 of the 86 net systems installed during the quarter represented repeats system sales to existing customers, which brings to 122, the total number of customers which own two or more da Vinci systems. Also, as of Q3, we have placed at least one da Vinci into all 50 states. International sales included two more than da Vinci placements into the countries of Korea, China, The Czech Republic and Greece. Clinically, we had another good quarter. In what is a seasonally slow quarter, we delivered solid procedure growth within several of our targeted surgical specialties. Procedure growth was led by da Vinci Hysterectomy both for benign and malignant conditions but most notably within dVH for benign conditions. Sacral colpopexy and myomectomy also showed excellent growth. Within our urology business, notably our kidney and bladder business, da Vinci Nephrectomy, and partial nephrectomy and da Vinci Cystectomy, showed excellent growth. Our U.S. dVP growth was steady, while our international dVP business was seasonally slower and lagged behind. Our cardiothoracic business remains steady. In Q3, there were over 180 da Vinci related clinical papers published within various peer-reviewed journals throughout several surgical specialties. And within limited Q3 medical conferences that took place during the quarter, several scientific abstracts, clinical posters and podium presentations highlighted da Vinci's clinical benefit. There were a number of favorable highlights from these various sources but I'll limit my review to a few. In the September edition of the Journal of Clinical Oncology, Dr. Ash Towori, Professor of Urology of Kernel University Medical Center provided a rebuttal to a comparative analysis of various surgical approaches to radical prostatectomy that was published in an earlier edition. Dr. Towori took issue with previous studies design and lack of clarity between traditional laparoscopic prostatectomy and dVP results, which for this particular study, were blended into a single minimally invasive radical prostatectomy category. To address this misleading results, Dr. Towori published his data on 1,170 dVP patients collected between 2005 and 2008. The results provided absolute transparency between the previously reported results for open prostatectomy minimally invasive radical prostatectomy and dVP. The comparison was striking. Comparing perioperative complications between the three cohorts showed open prostatectomy with a rate of 36.4% minimally invasive radical prostatectomy, 29.8% and dVP 1.64%. Hospital length of stay was 4.35 days for open, 1.42 days for minimally invasive radical prostatectomy compared to 1. 3 days for dVP. And finally, for asthmatic scriptures where the open prostatectomy rate was 12%, minimally invasive radical prostatectomy 15.2% compared to 0.54% with dVP, the significant of which has direct implications to desired urinary function. The two takeaways for me, from this study are as follows. First, the addition of the recently issued robotic specific DRG code will help to erase the misleading element of blending and reporting laparoscopic and robotic outcomes as similar. And second, the clinical outcomes between open prostatectomy and dVP are perhaps greater than we previously thought. The second study appeared in the August edition of Gynecologic Oncology and was offered... authored by Doctors Gary and Vagus, University of North Carolina, Chapel Hill. The authors' aim was to assess the most effective minimally invasive surgical treatment for endometrial cancer operations for obese and morbidly obese patients. Within this cohort, they compared traditional laparoscopic outcomes performed by laparoscopically skilled surgeons to their da Vinci outcomes. Obese and morbidly obese women are at a much higher risk of developing endometrial cancer and, according to this study, represents 33% of all U.S. women. The results of the study were as follows. For both the obese and morbidly obese patient, robotic surgery was associated with shorter operative times, 189 versus 215 minutes, less blood loss, 50 versus 150 milliliters, increased lymph node retrieval 31.4 versus 24 and shorter hospitalization. The authors' conclusion and I quote, Robotic surgery is a useful tool for comprehensive surgical staging for obese and morbidly obese women with endometrial cancer. As this patient population is at increased risk of death from all causes, including post-operative complications, all efforts should be made to improve their outcomes. The same University of North Carolina Group also published a comparative 322 patients study on endometrial cancer treatments which appeared in the October edition of the American Journal of Obstetrics and Gynecology. The purpose of this study was to compare total abdominal hysterectomy or TAH, total laparoscopic hysterectomy or TLH and da Vinci Hysterectomy or dVH within all clinical areas. When comparing para-aortic node retrieval between the three groups, they reported an average yield of three nodes within their TAH as their total abdominal hysterectomies. 6.3 nodes within their TLHs compared to 12 para-aortic lymph nodes within their da Vinci patients. When they compare total lymph node retrievals, they reported 14.9 within their TAHs, 23.1 within their TLHs and 32.9 within their da Vinci hysterectomies. Estimated blood loss between the three groups was as follows. 266 milliliters for their TAH patients, 145 for their TLH patients compared to 74 milliliters for their da Vinci hysterectomy patients. Length of hospitalization was reduced from an average of 4.4 days for their TAH patients to 1.2 days for their TLH patients to 1.0 days for the da Vinci hysterectomy patients, which led to the authors' conclusion, and I quote Total robotic hysterectomy with staging is feasible and preferable over total abdominal hysterectomy and may be preferable over total laparoscopic hysterectomy. This is a very strong endorsement especially so when you consider that the overwhelming majority of these procedures are performed through open incisions. My final reference is also specific to da Vinci's value within GYN Oncology and was authored by Dr. Limbandu and Harvingale [ph] from the Institute of Peritectomy [ph] in Marcey, France. And it appeared in the August edition of Surgical Endoscopy. The aim of this prospective study was to evaluate the feasibility and outcomes of GYN cancer surgery with the da Vinci S System. The patients underwent procedures consisting of total hysterectomy, bilateral inpherectomy [ph] and/or lumbo-aortic lymphadenectomy for endometrial, cervical or ovary cancer. Following the analysis of their data, the authors concluded by saying in a quote as suggested in the literature, the use of robotic laparoscopy leads to less blood loss, less post-operative pain and shorter hospitalizations days compared with those treated by more traditional surgical approaches. Despite the need for extensive studies robotic-assisted surgery seems to represent a similar technological evolution as the laparoscopic approach 50 years ago. All of these studies discussed da Vinci hysterectomy cancer outcomes. And I think it's important to reiterate that our fastest growing GYN procedure both in terms of absolute growth as well as percentage growth is dVH for benign conditions. That concludes my update and I'll now turn the time over to Ben.
