1. Description of Business Stereotaxis designs, manufactures and markets an advanced remote robotic navigation system for use in a hospitals interventional surgical suite, or interventional lab, that we believe revolutionizes the treatment of arrhythmias and coronary artery disease by enabling enhanced safety, efficiency, and efficacy for catheter-based, or interventional, procedures. Our products include the Genesis Robotic Magnetic Navigation System ( Genesis system), the Niobe ES Robotic Magnetic Navigation System ( Niobe ES system), Odyssey Information Management Solution ( Odyssey Solution), the Vdrive Robotic Navigation System ( Vdrive system), Stereotaxis Imaging Model S x-ray system, and related devices. The Genesis and Niobe systems are designed to enable physicians to complete more complex interventional procedures by providing image-guided delivery of catheters and guidewires through the blood vessels and chambers of the heart to treatment sites. This is achieved using externally applied magnetic fields that govern the motion of the working tip of the catheter or guidewire, resulting in improved navigation, efficient procedures, and reduced x-ray exposure. As of March 31, 2019, the Company had an installed base of 126 Niobe ES systems. In addition to the robotic magnetic navigation systems and their components, Stereotaxis also has developed the Odyssey Solution, which consolidates all lab information enabling doctors to focus on the patient for optimal procedure efficiency. The system also features a remote viewing and recording capability called Odyssey Cinema , which is an innovative solution delivering synchronized content for optimized workflow, advanced care, and improved productivity. This tool includes an archiving capability that allows clinicians to store and replay entire procedures or segments of procedures. This information can be accessed from locations throughout the hospital local area network and over the global Odyssey Network providing physicians with a tool for clinical collaboration, remote consultation, and training. Our Vdrive system provides navigation and stability for diagnostic and therapeutic devices designed to improve interventional procedures. The Vdrive system complements the robotic magnetic navigation systems control of therapeutic catheters for fully remote procedures and enables single-operator workflow and is sold as two options, the Vdrive system and the Vdrive Duo system. In addition to the Vdrive system and the Vdrive Duo system, we also manufacture and market various disposable components which can be manipulated by these systems. We promote our full suite of products in a typical hospital implementation, subject to regulatory approvals or clearances. This implementation requires a hospital to agree to an upfront capital payment and recurring payments. The upfront capital payment typically includes equipment and installation charges. The recurring payments typically include disposable costs for each procedure, equipment service costs beyond warranty period, and ongoing software updates. In hospitals where our full suite of products has not been implemented, equipment upgrade or expansion can be implemented upon purchasing of the necessary upgrade or expansion. The Niobe System, Odyssey Workstation, Cardiodrive, and various disposable interventional devices have received regulatory clearance in the U.S., Europe, Canada, China, Japan and various other countries. We have received the regulatory clearance, licensing and/or CE Mark approvals that allow us to market the Vdrive and Vdrive Duo systems with the V-CAS , V-Loop and V-Sono devices in the U.S., Canada and Europe. The Genesis system and the V-CAS Deflect catheter advancement system have been CE Marked for sale in the Europe. Stereotaxis Imaging Model S is CE marked and FDA cleared. We have strategic relationships with technology leaders in the global interventional market. Through these strategic relationships we provide compatibility between our robotic magnetic system and digital imaging and 3D catheter location sensing technology, as well as disposable interventional devices, in order to continue to develop new solutions in the interventional lab. The maintenance of these strategic relationships, or the establishment of equivalent alternatives, is critical to our commercialization efforts. The commercial availability of currently compatible digital imaging fluoroscopy systems is unlikely to continue and efforts are being made to ensure the availability of integrated next generation systems and/or equivalent alternatives; however, we cannot provide assurance as to the timeline of the ongoing availability of such compatible systems or our ability to obtain equivalent alternatives on competitive terms or at all.
