Abstract
A catheter includes a shaft for insertion into an organ of a patient, and an expandable distal-end assembly, which is coupled to the shaft and to an apex of the catheter, and includes multiple splines. In at least a given spline among the multiple splines, at least sixty percent of a length of the given spline is non-insulated and is configured to make contact with tissue of the organ and to apply radiofrequency (RF) pulses to the tissue.
Claims14
A catheter, comprising:
- a shaft for insertion into an organ of a patient, the shaft extending along a longitudinal axis;
- and
- an expandable distal-end assembly, which is coupled to the shaft and to an apex of the catheter, and comprises multiple splines, wherein, in at least a given spline among the multiple splines, at least 60 percent of a length of the given spline is non-insulated and is configured to make contact with tissue of the organ and to apply radiofrequency (RF) pulses to the tissue;
- and
- a bump stop, which is coupled to the apex and is configured to limit a minimal distance along the longitudinal axis between the shaft and the apex, the bump stop being separated from a tip of the shaft with an axial gap between the tip and the bump stop.

A method for producing a catheter, the method comprising:
- receiving multiple splines, wherein, in at least a given spline among the multiple splines, at least 60 percent of a length of the given spline is non-insulated and is configured to make contact with tissue of an organ of a patient and to apply radiofrequency (RF) pulses to the tissue;
- assembling the multiple splines together for producing an expandable distal-end assembly;
- and
- coupling the expandable distal-end assembly to a shaft and to an apex of the catheter with a bump stop disposed between the shaft and the apex to ensure a gap therebetween.
