1. A catheter configured to be used in a medical procedure, the catheter comprising:
a shaft for insertion into an anatomical structure of a patient, the shaft extending along a longitudinal axis, the shaft comprising a distal tip;
an expandable distal-end assembly, coupled to the shaft and to an apex of the catheter, and comprises multiple splines, each spline of the multiple splines being formed from an electrically conductive material, at least 60 percent of a length of at least one spline being non-insulated and being configured to make contact with tissue of the anatomical structure and to apply electrical pulses to the tissue; and
a bump stop coupled to the apex of the catheter and configured to contact the distal tip of the shaft to maintain a minimal distance between the apex of the catheter and the distal tip of the shaft when a force is applied to the expandable distal-end assembly.
