Welcome everyone to today's webinar. Intravascular Robotics: Reshaping Vascular Intervention. Today's event is being presented by Hansen Medical, the global leader in Intravascular Robotics. Here is our agenda for today. We have two presenters. Dr. Bismuth will provides an introduction to intravascular robotics and then Dr. Lumsden will describe the clinical experiences with intravascular robotics at Houston Methodist Hospital. Our first presenter is Dr. Jean Bismuth. Dr. Bismuth is a vascular surgeon and an assistant professor at the Methodist Debakey Heart and Vascular Center at the Houston Methodist Hospital in Houston, Texas. Dr. Bismuth and our second speaker Dr. Lumsden have been closely involved in the development if intravascular robotics technology from the beginning. Dr. Bismuth has focused his research interests on vascular surgery robotics as well as vascular surgery training and simulation development. He led and published a pivotal 20 patient first-in-man trial of a general robotics system that led to FDA 510k clearance in 2012 and he is currently a principal investigator on the ROVER registry which is a post market multicenter study of the first 500 cases being performed globally with the Magellan robotics system. Thank you for joining us today Dr. Bismuth and I'll now be turning it over to you.
Dr. Jean Bismuth:
Thank you Brian, and thanks for tuning in and listening to this webinar which is hopefully going to be informative for those of you who are interested in intravascular robotics. As Brian mentioned, we have been involved in this for some years now, about five to six years. And so, I think we have determined what the need for robotics is along the way. One of the things we see in a lot of our cases is they can be long, complex and somewhat unpredictable. We think that potentially, the robotics have a way of making this a more predictable procedure. There are some discrepancies in training and skill sets. We see that when we train our residents and fellows. This could potentially bridge that gap. Physicians are, as we know, suffering radiation and orthopedic injuries. I'll go into the radiation bit in just a little bit. And then complex cases, as you know, can be difficult, sometimes leading to complications that potentially could be avoided.
If you look at radiation injuries, as you know they're cumulative and they're permanent. And so, we start talking about more complex procedures, well potentially if you can remove the whole component of driving to the site of interest, you can potentially also reduce the amount of radiation you're exposed to. This is just an image from a publication in 2009. We are looking at skin injury and again looking at the fatal risk cancer, predict fatal risk cancer. If you look at the robotic system itself, we are talking about The Magellan Robotic System. There are two main components to the driving. One is the Remote Catheter Manipulator which has essentially has two attachments for the two catheters, which I'll go in and explain a little bit more carefully in a second, and then is had the Remote Wire Manipulator which is on the back end, essentially consisting of two belts which can drive the robot, pull it back and also torque it. This is the physician work station. Now this is not the only component from which you can drive. There is also a pendant, which is at bedside, which allows you to do everything you see here except for the 3D controller. So primarily, I personally navigate with the buttons but we do use the 3D controller as well. The foot pedal allows you to shift between the leader, which is the equivalent of your diagnostic catheter and the sheath which would be the equivalent of which you would sheath of any case.
This is a video of just going through the details of the mechanism. You saw there the workstation, here is the RCM and the catheter being loaded onto it. You can then see from the workstation how you can control the guide wire, driving it and retracting it. Also here you can see how you can torque it.
