Abstract: A catheter with tactile indication of deflection, comprising a shaft, a control handle with a housing configured with an indent, and a deflection lever mounted on the housing over the indent and configured to deflect the shaft with rotation of the deflection lever. The deflection lever includes a ball bearing and a spring screw configured to mobilize the ball bearing into elastic contact with the indent when the deflection lever is rotated into a neutral position, where the engagement between the ball bearing and the indent provides a tactile indication of shaft deflection detected by an operator holding the deflection lever.

Abstract: A method for displaying information includes receiving measurements, with respect to an invasive probe inside a body of a subject, of probe parameters consisting of a force exerted by the probe on tissue of the subject and temperatures measured by sensors of the probe; and responsively to the measurements, displaying in a single map on a display screen a graphical representation of a distribution of the temperatures in a vicinity of the probe and superimposing thereon a vector representation of the force, wherein the single map includes a color map based on an auto-adjust color scale. In some embodiments, the auto-adjust color scale includes a selected color that represents a maximum temperature equal to a maximum measured temperature increased by a predetermined number of degrees. In some embodiments, the auto-adjust color scale includes a selected color that represents a minimum temperature equal to a measured tissue temperature before ablation.
