Abstract
A hub assembly for a robotically driven interventional device can include an interventional device hub having an interventional device and at least one magnet. The hub assembly can be configured to be positioned on a sterile side of a sterile field barrier and magnetically couple to a hub adapter on a non-sterile side of the sterile field barrier so that hub assembly moves axially in response to axial movement of the hub adapter and the at least one magnet of the hub assembly rotates in response to rotation of at least one magnet of the hub adapter.

A hub assembly for a robotically driven interventional device, comprising:
- an interventional device hub having a body and a flexible elongate interventional device extending from the body, the interventional device comprising a longitudinal axis;
- and
- at least one magnet comprising a rotational axis, the at least one magnet being coupled to the body and being rotatable relative to the body,
- wherein the hub assembly is configured to be positioned on a sterile side of a sterile field barrier and magnetically couple to a hub adapter on a non-sterile side of the sterile field barrier so that the hub assembly moves axially in response to axial movement of the hub adapter and the at least one magnet of the hub assembly rotates in response to rotation of at least one magnet of the hub adapter;
- wherein the at least one magnet is operatively coupled to the interventional device so that rotation of the at least one magnet of the hub assembly about the rotational axis causes rotation of the interventional device about the longitudinal axis;
