Abstract
A drive mechanism for a robotic catheter system including a first engagement surface and a second engagement surface is provided. The first engagement surface and second engagement surface are configured to engage a catheter device to allow the drive mechanism to impart motion to the catheter device. The first engagement surface is textured to facilitate gripping between the first engagement surface and the catheter device.
Claims22
A drive mechanism for a robotic catheter system which imparts both axial and rotational motion comprising:
- a tire of a drive wheel and a tire of an idler wheel which interact with each other, each of which has an engagement surface which interacts with a catheter device to cause it to move along its axis and which is free of any gripping features which run perpendicular to the axis of the catheter device;
- and
- a set of rotational drive assembly wheel tires each of which has an engagement surface which interacts with a catheter device to cause it to rotate about its axis and which has a gripping feature which runs perpendicular to the axis of the catheter device.
A drive mechanism for a robotic catheter system which imparts both axial and rotational motion comprising:
- a drive wheel tire and an idler wheel tire which interact with each other, each of which has an engagement surface which interacts with a catheter device to cause it to move along its axis;
- and
- a set of rotational drive assembly wheel tires each of which has an engagement surface which interacts with a catheter device to cause it to rotate about its axis;
- wherein one or more of the tires has a composite structure in which a material or structure of higher resilience is interposed between its engagement surface and the hub on which it is mounted.
