1. A method, comprising:
- providing an elongated probe having a longitudinal axis and a distal end, and capable of rotation of the distal end about the longitudinal axis in mutually opposite first and second directions, the distal end comprising an end section formed to define an arc that is oriented obliquely to the longitudinal axis;
while an operator manipulates the probe within a body of a patient, automatically sensing the rotation that is applied to the distal end; and
automatically detecting an abnormality in the shape of the distal end of the elongated probe and issuing an alert to the operator upon sensing that the rotation is in the second direction, but not when sensing that the rotation is in the first direction, the alert allowing the operator to prevent the distal end of the elongated probe from engaging onto tissue and preventing damage to the tissue.

Abstract
A method includes providing an elongated probe having a longitudinal axis and a distal end, and capable of rotation of the distal end about the longitudinal axis in mutually opposite first and second directions. While an operator manipulates the probe within a body of a patient, the rotation that is applied to the distal end is sensed automatically. An alert is issued to the operator upon sensing that the rotation is in the second direction, but not when the sensed rotation is in the first direction.

14. An apparatus, comprising:
- a processor, which is connected to an elongated probe that has a longitudinal axis and a distal end and is capable of rotation of the distal end about the longitudinal axis in mutually opposite first and second directions, the distal end comprising an end section formed to define an arc that is oriented obliquely to the longitudinal axis, wherein the processor is configured to automatically sense the rotation that is applied to the distal end while an operator manipulates the probe within a body of a patient, and to automatically detect an abnormality in the shape of the distal end of the elongated probe and to issue an alert upon sensing that the rotation is in the second direction, but not when sensing that the rotation is in the first direction; and
an output device, which is configured to present the alert to the operator, the alert allowing the operator to prevent the distal end of the elongated probe from engaging onto tissue and preventing damage to the tissue. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
