Well, I would just comment at a high level, I think Neuro Critical Care and Tissue Ablation both globally had some strong performances. We've spent a lot of time within that organization, both domestically and internationally, on sales process and scale. And we continue to do well, I think, on the critical care side. We do have an installed base that we've been working through and still have had some pretty good performance of converting some older technologies out. I think on Tissue Ablation, the market continues to be reasonably robust. We've got a leadership product within that space, the CU.S.A brand and really a very strong sales force that's developed its skills, I'd say, to kind of really figure out how to not just sell the technology, but we've increased the capabilities of the device in added indications, such as liver on top of neurosurgery. And so that's added to the ROI for a given customer. And I think the organization has done a nice job of selling that value. As far as regenerative, look, we had a, I think, we thought, a very good in-line performances as we had expected. As Glenn commented on, TEI year-over-year was down, but it was up sequentially, as we had hoped, in line with some of the investments and changes that were made. Very bullish about the future of the TEI capabilities. Again, it's quite complementary. And we actually have some new products lined up to come out in 2017 into 2018. But we've made some good progress there. Our core business is doing very well. I would say, from our original platform the Company is founded on which is the larger IDRT templates, we're starting to see, in many cases, even on the inpatient side, where certain surgeons would use lower-tech products in the past, are now stepping up to use products such as our IDRT as a first-line product. And with that, we're starting to see some good growth. And we've been seeing that throughout the year. And those are the kind of trends that we think are going to continue. And so if you look at the quarter, it was really a broad-based consistent strength that we've had. And again, a little bit more weaknesses in TEI, as we had foreseen.
