Tissue biopsy and treatment apparatus and method

A tissue biopsy and treatment apparatus for detecting and treating tumors, the apparatus comprising:

• an elongated delivery device including a lumen, the elongated delivery device being maneuverable in tissue;
• a sensor array deployable from the elongated delivery device, the sensor array including a plurality of resilient members each having a tissue piercing distal portion, at least one of the plurality of resilient members being positionable in the elongated delivery device in a compacted state and deployable with curvature into tissue from the elongated delivery device in a deployed state, at least one of the plurality of resilient members including an optical sensor operatively connected to function as an emitter and a detector, the sensor array having a geometric configuration adapted to volumetrically sample and measure a spectral profile of at least one portion of a tissue site to differentiate or identify tissue at the tissue site, and an optical switching device to switch a mode of said optical sensor;
• and
• at least some of said resilient members being electrodes which can be coupled to an RF energy source for ablating tissue when electrical energy is supplied to the electrodes from the sources.
