A method of treating a tumor includes providing a tissue biopsy and treatment apparatus that includes an elongated delivery device that has a lumen and is maneuverable in tissue. A sensor array having a plurality of resilient members is deployable from the elongated delivery device. At least one of the plurality of resilient members is 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 includes at least one of a sensor, a tissue piercing distal end or a lumen. The sensor array has a geometric configuration adapted to volumetrically sample tissue at a tissue site to differentiate or identify tissue at the tissue site. At least one energy delivery device is coupled to one of the sensor array, at least one of the plurality of resilient members or the elongated delivery device. The apparatus is then introduced into a target tissue site. The sensor array is then utilized to distinguish a tissue type. The tissue type information derived from the sensor array is utilized to position the energy delivery device to ablate a tumor volume. Energy is then delivered from the energy delivery device to ablate or necrose at least a portion of the tumor volume. The sensor array is then utilized to determine an amount of tumor volume ablation.

The present invention relates to a method of fabricating a microstructure having an inside cavity comprising the steps of: depositing a first layer or a first stack of layers in a substantially closed geometric configuration on a first substrate; performing an indent on the first layer or on the top layer of said first stack of layers; depositing a second layer or a second stack of layers substantially with said substantially closed geometric configuration on a second substrate; aligning and bonding said first substrate on said second substrate such that a microstructure having a cavity is formed according to said closed geometry configuration.
