Abstract

A thermal surgical tool comprising a conductor having a ferromagnetic material attached thereto is provided. The conductor may include a support of sufficiently high Young's modulus to resist bending when the surgical tool is being used to treat tissue. One or more intervening layers may be disposed between the support and the ferromagnetic material. Each of the intervening layers may be selected for a property that facilitates construction of the surgical tool and/or enhances a functionality of the surgical tool. The thermal surgical tool can be used for separating tissue, coagulation, tissue destruction or achieving other desired tissue effects in numerous surgical procedures.
