Title: Loop structures for supporting multiple electrode elements

Abstract: A catheter assembly comprises a sheath, which includes a side wall enclosing an interior bore, a distal region, and an opening in the sidewall. The assembly also comprises a bendable catheter tube, which is carried for sliding movement in the interior bore. The catheter tube has a distal portion. The assembly further comprises a coupling, which joins the distal region of the sheath and the distal portion of the catheter tube. The coupling causes bending of the catheter tube outwardly through the opening, in response to sliding movement of the catheter tube within the interior bore toward the distal region of the sheath.
