Rafaelo's technique consists of delivering a low-temperature 4 MHz radiofrequency wave current into the haemorrhoidal vascular tissue using a large single-use needle with microfibre electrodes at the end.

"The aim of arterial ligation is to de-arterialise the haemorrhoids by reducing the arterial flow of the haemorrhoidal plexuses while avoiding obstructing the venous return."
