Abstract
An electrosurgical instrument is manufactured by presenting an electrode (1), and attaching a sacrificial portion (6) to the electrode (1) to form a first electrode assembly. An insulating material (9) is moulded over the first electrode assembly to form a second electrode assembly, and the second electrode assembly is subjected to a further process which is capable of removing the sacrificial portion (6) without removing the insulating material (9). The sacrificial portion (6) is removed to form at least one cavity within the electrosurgical instrument.
