ABSTRACT:
An electrode catheter for temporary use comprises a biocompatible sheath with a distal end and a proximal end connected to means for commanding and controlling sent or recorded electrical signals; on the sheath is provided an ogive element, fitted to close the distal end, made of conductive material and connected with a first conducting wire so as to define a first electrical pole; a flexible reinforcing core integral with the ogive element to guarantee an ergonomic conformation of the sheath; a first metal ring fastened to the exterior of the sheath and connected to a second conducting wire extending inside the sheath so as to define a second pole, and lastly a spiral element, elastically yielding, set coaxially to the first wire and to the core and electrically isolated; this spiral element covers a length equal to the distance between the ogive element and the first ring allowing it to be deformed elastically with the related adaptation of the length both to the conformation, and to the variation in the conformation of a cardiac cavity, to provide a stable contact with a wall of the cardiac cavity itself.
