WHEEL FOR ROBOTIC CATHETER SYSTEM DRIVE MECHANISM

摘要

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.

主权项

1. A drive mechanism for a robotic catheter system, the drive mechanism being configured to impart both axial and rotational motion to a catheter device and 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 is configured to interact with a catheter device to cause it to move along its longitudinal axis and which is free of any slits that each have a centerline configured to run perpendicularly to the longitudinal axis of the catheter device; and a set of rotational drive assembly wheel tires each of which has an engagement surface which is configured to interact with the catheter device to cause it to rotate about its longitudinal axis and which have slits each having a centerline configured to run perpendicularly to the longitudinal axis of the catheter device.
