1. Apparatus, comprising:
a guidewire, comprising a flexible biocompatible tube having a tube distal end configured to be inserted into an orifice of a body of a living subject;
a camera fixed in proximity to the tube distal end;
a pair of biocompatible electrodes, formed on an outer surface of the flexible biocompatible tube at the tube distal end, configured to contact tissue of the body; and
a processor, configured:
to inject a signal via the electrodes, so as to electrically stimulate the contacted tissue; and in response to the stimulation, to provide an indication if the tissue is fibrotic, wherein the indication is provided in response to visible motion of the contacted tissue occurring detected based on images captured by the camera.
