Abstract:
1. A multi-mode surgical tool comprising: an electrosurgical electrode and a thermal element comprising a conductor and a ferromagnetic layer covering at least a portion of the conductor, the ferromagnetic layer forming a ferromagnetic region disposed along the conductor, the conductor extending from a position prior to the ferromagnetic layer, through the ferromagnetic region and to a position beyond the ferromagnetic layer, the ferromagnetic layer being sufficiently thin that the ferromagnetic layer will not fracture when the ferromagnetic layer is heated in air and then immersed in liquid while the ferromagnetic layer is heated; wherein passage of electrical energy from a conductor location prior to the ferromagnetic region to a conductor location beyond the ferromagnetic region causes heating of the ferromagnetic layer.
