Thank you, Greg. Our focus for the last several quarters has been centered on preparing for advisory committee or panel meeting with the FDA, as part of a larger goal of achieving regulatory approval in the U.S. of the Maestro System as a treatment for obesity with the June 17th date now scheduled and published in the federal register we are closer than ever to achieving this goal. The obesity epidemic is one widely described by the medical community and regulators as a serious and urgent threat to the public health. Among existing options for treating this disease, there exists a significant gap in the treatment spectrum as evidenced by the lack of progress in reducing the rates of obesity. We believe that VBLOC Therapy may fit in this gap as a unique alternative to options that are either ineffective or fail quickly, or which patients avoid for fear of adverse safety and lifestyle effects. VBLOC is a safe, effective and patient-friendly option for those seeking a long-term solution to achieve their health and weight loss goals. It works by controlling, both hunger fullness while promoting healthy weight loss without punitive dietary or other long-term side effects. EnteroMedics has built significant experience with VBLOC Therapy. More than 600 patients having done implanted with the Maestro System to-date, some received their devices over five years ago. The cornerstone of our regulatory effort is the five year ReCharge Pivotal Trial for which we have announced safety and efficacy results at 12 and 18 months. At 12 months the trial demonstrated statistically significant, durable and medically meaningful weight loss of 24.4% excess weight loss compared to a sham control group weight loss of 15.9%, a superior record of safety was also demonstrated with a 3.7% related serious adverse event rate, well below the pre-specified threshold of 15%. At 18 months, patients maintained their weight loss at about 25% with a very similar safety profile and a 4.3% related serious adverse event rate. Under a variety of analysis including as observed or completed data and various modeling methods such as last observation carry forward, mixed effect models, regression and multiple amputation, all of which have been presented to the FDA, these data remain robust, ranging from 24% to 28% excess weight loss at 12 months and 21% to 26% at 18 months. Significantly in addition to maintaining their clinically important weight loss at 18 months, the VBLOC group widened the difference in weight loss over the sham from 8.5% to over 13%. The sham group gained back 40% of the weight loss they had achieved during this time with the majority of the weight gain occurring under blinded study conditions, underscoring the unfortunate reality of most people with obesity and their attempts to lose weight. These 12 and 18 month results demonstrate the attractive benefit risk profile of VBLOC Therapy. While ReCharge did not meet its pre-defined efficacy endpoints, we believe that this was an effect of the study design rather than a reflection on the benefit of this revolutionary technology. Given the strong safety profile and significant medically meaningful weight loss we anticipate a productive discussion with the panel this June and look forward to continued open dialog with the FDA leading into their approval decision anticipated for this year. While the regulatory pathway continues to be our priority moving forward, we have also begun to prepare for U.S. commercialization in the areas of sales, marketing and reimbursement. We continue to explore all potential strategic partnering relationships on a geographic and indication basis, while simultaneously planning for the initial commercial rollout of the Maestro System in the United States. As we have highlighted in the past, we believe this rollout can be achieved with a limited sales and field support staff targeting our current clinical centers. As part of the future commercial team, we announced earlier this month that we appointed Mark Bullivant as our Vice President of Marketing. His extensive marketing experience, both in and outside of the United States, will be important as we translate our experience into a successful U.S. commercialization effort. Another part of this effort is moving forward in establishing third-party reimbursement. To-date we have received six new Category III CPT codes from the American Medical Association, which we anticipate will support Category I CPT payment codes in the future following FDA approval of VBLOC Therapy. The Category III CPT codes are important because they have allowed us to begin preliminary discussions with private insurers about our technology and the benefits of our approach to treating obesity and its comorbidities such as diabetes and hypertension. While our efforts in the U.S. currently consume the majority of our resources and attention, we continue to work on several ex-U.S. initiatives. In Australia, we are focused on reimbursement for the implantation procedure and our device in parallel. Reimbursement of the hospital and surgeon is reliant upon obtaining an item number code while listing on the Prostheses List secures reimbursement for our device. Covering a greater breadth of markets, our team is also working to enhance our Maestro System CE Mark for obesity to include two new indications, one for diabetes and one for hypertension. Once our pathway in the U.S. is clear we expect to accelerate our activities in these territories, as well as exploring new geographies where the Maestro System holds meaningful commercial potential. With that, I will now turn the call back over to Greg to cover our financials for the quarter.
