Abstract: An adjustable, structure providing an ablation apparatus, having a preformed structure made from compliant material such as rubber like material, foam or gel, with particles made of electromagnetic energy absorbing material. An antenna for radiating emitted microwave energy to generate heat and thus cause cavity ablation is located inside of the conformable adjustable structure. When end effector portion is inserted into the body cavity, the compliant adjustable structure is compliant to conform to a profile of the cavity to be ablated, and microwave energy is received to heat the adjustable structure resulting in heat energy that will ablate the cavity tissue in contact with the compliant end effector. Additionally, the shape of the end-effector compliant structure can be differently formed, depending of shape of tissue cavity to be ablated.

Abstract: Disclosed is a working end of a surgical instrument for delivering heat energy to tissue. The working end includes paired first and second jaw members movable between open and closed positions, with each jaw member defining a jaw body and jaw end-effecter for engaging and heating tissue. At least one jaw member contains an electromagnetic-energy emitter coupled to an electromagnetic-energy source, the electromagnetic-energy emitter is located within the jaw end-effecter, and the jaw end-effecter includes an insert made of an electromagnetic-energy absorbing material.

Abstract: Disclosed is a method and an apparatus for ablating biological tissues, in which a cannula is configured to affect biological tissue and a heat transmitting end-effecter is coupled to the cannula. A source of electromagnetic energy is provided via an electro-magnetic energy emitter and a wall of the heat transmitting end-effecter is made of an electromagnetic-energy-absorbing material that absorbs electromagnetic waves.

Abstract: Disclosed is an apparatus for ablating biological tissues, the apparatus is configured with a cannula, a balloon inflatable with a gaseous medium and coupled to the cannula, and an electromagnetic antenna coupled to the balloon operative to emit electromagnetic waves which heat the wall of the balloon. The wall is made from wave penetrating material impregnated with a plurality of wave absorbing particles which are heated to the desired ablation temperature by the absorbed electromagnetic waves.
