Classification: CPC A | IPC A

Claim 12:
13. 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 apex of the catheter positioned distal to the distal tip of the shaft;
an expandable distal-end assembly longitudinally interposed between the distal tip of the shaft and the apex of the catheter, the expandable distal-end assembly comprising multiple splines, each spline of the multiple splines being formed from an electrically conductive material and configured to contact tissue of the anatomical structure and to apply electrical energy to the tissue;
a coupling element, the expandable distal-end assembly being coupled to the shaft via the coupling element; and
a bump stop extending proximally from the apex of the catheter, the bump stop being configured to limit a minimal distance along the longitudinal axis between the shaft and the apex of the catheter by contacting the distal tip of the shaft when a force is applied to the expandable distal-end assembly.
