Adjustable end effector structure for tissue ablation

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.
