Tissue Ablation System With Internal And External Radiation Sources

A microwave ablation system, comprising:

• a plurality of energy sources adapted to generate microwave energy;
• and
• a plurality of energy delivery devices each of which is coupled to a corresponding one of the plurality of energy sources, the plurality of energy delivery devices including:
• at least one first energy delivery device configured to be inserted into tissue and to generate a non-directional ablation volume;
• at least one second energy delivery device configured to be positioned relative to the tissue and to generate a directional ablation volume.

A method for providing energy to a target tissue, comprising the steps of:

• coupling a plurality of energy delivery devices including at least one non-directional energy delivery device and at least one directional energy delivery device to a power dividing device having an input adapted to connect to an energy source;
• inserting the at least one non-directional energy delivery device into a portion of the target tissue;
• positioning the at least one directional energy device at a surface of the target tissue;
• selectively dividing energy on a plurality of channels to the plurality of the energy delivery devices;
• and
• applying energy from the plurality of energy delivery devices to the target tissue.
