Abstract
A method includes, while an operator of an elongated probe, having proximal and distal ends, manipulates the proximal end so as to move the distal end within a body of a patient, automatically measuring a cumulative angle of rotation that is applied by the operator to the proximal end. An indication of the cumulative angle of rotation is presented to the operator.

A method for assisting an operator of a probe in correcting, reducing or preventing over-rotation and entanglement of the probe, comprising:
- using an elongated probe having a body and a distal end and a proximal end, and a position sensor, which is coupled to the body of the elongated probe and is configured to generate signals used for determining location and orientation coordinates of the probe that are indicative of the rotation applied to the proximal end of the probe by an operator;
- manipulating the proximal end of the probe so as to move the distal end within a body of a patient, automatically measuring a cumulative angle of rotation that is applied by the operator to the proximal end based on the location and orientation coordinates of the probe;
- and
- presenting an indication of the cumulative angle of rotation of the probe on a display to the operator in order to assist the operator in correcting, reducing or preventing over-rotation of the probe.
Apparatus for assisting an operator of a probe in correcting, reducing or preventing over-rotation and entanglement of the probe, comprising:
- the probe, comprising:
- an elongated body having a distal end and a proximal end wherein the proximal end is capable of rotation by the operator;
- and
- a position sensor, which is coupled to the body and is configured to generate signals used for determining location and orientation coordinates of the probe that are indicative of the rotation applied to the proximal end by an operator;
- a display;
- and
- a processor, which receives the signals from the position sensor and determines location and orientation coordinates of the probe wherein the processor is configured to estimate a cumulative angle of rotation responsively to the signals from the position sensor, and to present an indication of the cumulative angle of rotation to the operator based on the location and orientation coordinates of the probe to assist the operator in correcting, reducing or preventing over-rotation of the probe.
