    Abstract: A robotic catheter control system includes a collision detection logic configured to determine a collision metric indicative of a collision between a medical device that is manipulated by the robotic control system and an object. The object may be an anatomical feature or can be another medical device, including another device being manipulated by the robotic control system. The collision detection logic produces virtual representations of the medical device and the object and uses these representation to determine collision. Geometrical solids, such as spheres, are used to represent the outer surfaces of the devices and the logic determines whether the respective surfaces intersect, thereby indicating collision. Collision avoidance involves estimating future device poses and then computing an alternate path computation so as avoid predicted collision(s).

    Abstract: An embodiment of a handle assembly for an elongate medical device that may reduce the weight and/or expense of traditional handle may include an exterior adjusting knob extending along a longitudinal axis and configured to rotate about the axis, an insert, and a dowel pin. The insert may be configured to engage the adjusting knob and to rotate about the axis responsive to rotation of the adjusting knob. The insert may comprise an annular groove configured to engage a dowel pin, the annular groove comprising a sidewall comprising a chamfer. The dowel pin may be configured to engage the annular groove to resist rotation of the insert. In an embodiment, the insert may comprise plastic or polymer.
