Abstract
An ablation catheter and a method of performing cardiac ablation using alcohol or other ablating agents. The catheter is provided with a helical hollow needle, which is screwed into heart tissue, after which the ablating agent is delivered through the needle. Prior to ablation, the catheter may be employed to locate an appropriate ablation site or to assess the suitability of an identified ablation site by injection of a exitability reducing agent such as lidocaine, through the hollow needle, followed by a determination of whether the arrhythmia intended to be treated as temporarily terminated.
