Abstract

An ablation arrangement (1) for the targeted production of local lesions in living tissue inside the body, particularly inside the heart, comprising at least one energy source (15), a plurality of energy uncoupling elements (11b to 11g) that are attached to a holding element (11a), a plurality of energy transmission lines (19.1) that connect the energy source or the energy sources to the energy uncoupling elements and switching elements (9.3) that are assigned to the energy transmission lines for setting up or interrupting a connection between the energy source and respectively one energy uncoupling element, with program control means (9.1) for a time-sequential actuation of at least some of the switching elements according to an ablation program.
