First Claim
1. A computer implemented method comprising:
- activating a control mechanism on a catheter handle in a first direction with respect to a user to steer a distal end of a catheter within a body in a second direction while the catheter handle is in a first rotational position, the control mechanism including a first indicator associated with the first direction;
obtaining an image from the distal end of the catheter of a tissue region of interest within the body;
calibrating a first rotational motion of the catheter handle with a rotational motion of the image; and
with the catheter handle in a second rotational position that is different than the first rotational position, activating the control mechanism in the first direction with respect to the user to move the distal end of the catheter in the second direction.

Abstract
A computer implemented method comprises activating a control mechanism on a catheter handle in a first direction with respect to a user to steer a distal end of a catheter within a body in a second direction while the catheter handle is in a first rotational position. The control mechanism includes a first indicator associated with the first direction. The computer implemented method also includes obtaining an image from the distal end of the catheter of a tissue region of interest within the body and calibrating a first rotational motion of the catheter handle with a rotational motion of the image. With the catheter handle in a second rotational position that is different than the first rotational position, the control mechanism activated in the first direction with respect to the user moves the distal end of the catheter in the second direction.
