Last month, the team at Activ Surgical achieved a critical milestone as we announced our first peer-reviewed study and publication in Surgical Endoscopy using our ActivSight™ Intelligent Light Visualization System. Today, we are pleased to be sharing the news that a second peer-reviewed study and paper has been published in another leading medical journal–Current Urology. The study brought together one of the most well-respected names in urologic robotic-assisted surgery, Dr. Vipul Patel, as well as his then-fellow, Dr. Jonathan Noel, to investigate how Intelligent Light signals for kidney perfusion can be utilized in partial nephrectomy.
The team used our FDA-cleared ActivSight Intelligent Light System during a minimally-invasive procedure of an anesthetized porcine kidney model, allowing the team of surgeons to explore multimodal advanced visualization. Our patented ActivPerfusion™ mode, which integrates laser speckle contrast imaging to detect real-time blood flow and perfusion, was employed together with ActivICG™ mode, providing traditional near infrared visualization of indocyanine green dye (ICG). ActivICG and dye-free ActivPerfusion displayed visual concordance of regional perfusion in response to clamping of the upper segmental artery. Furthermore, it was observed that ActivPerfusion avoids dye-related latency and potential false-positive results from dye retention.
Dr. Patel and Dr. Noel, along with their team of colleagues, were thrilled with the results of this study, which support potential ActivSight utility for renal parenchymal perfusion assessment. Of equal importance, they agree that ActivSight multimodal enhanced visualization may allow for the rapid advancement of digital surgery.
All of us at Activ Surgical express our appreciation to Dr. Patel and Dr. Noel for leading this study and the subsequent paper publication in Current Urology. We are also grateful to Dr. Moschavas, Dr. Liu, Dr. Mehrota, Dr. Nwaiwu, Anya Mascarenhas and Activ Surgical founder and CSMSO Dr. Peter Kim for their involvement and efforts in completing this study. These studies and the publication of their findings play an important role as we continue to work towards global commercialization of ActivSight Intelligent Light Visualization System later this year.
