Abstract

Concentric tube robots are comprised of telescoping precurved superelastic tubes. Their shape is controlled by rotating and translating the tubes with respect to each other at their base. With diameters of 1-4mm, they are well suited for minimally invasive medical applications.  Invented by my group just over a decade ago, the theory for designing, modeling and controlling these robots is now well developed and recent work has focused on identifying the best clinical applications for this technology. This talk will cover two applications. The first employs a concentric tube robot as a cardiac catheter for performing heart valve repair. Here, we demonstrate autonomous control of catheter navigation inside the heart through in vivo experiments. The second application explores the use of concentric tube robots as arms for bimanual single-port systems. This application is evaluated in the context of endoscopic neurosurgery where we define a set of bimanual tasks associated with tumor removal and compare standard single-tool endoscopy with the two-armed robot system.
