Abstract: Systems and methods for ablating tissue include an ablation device having an energy source and a sensor. The energy source provides a beam of energy directable to target tissue, and the sensor senses energy reflected back from the target tissue. The sensor collects various information from the target tissue in order to facilitate adjustment of ablation operating parameters, such as changing power or position of the energy beam. Gap distance between the energy source and target tissue, energy beam incident angle, tissue motion, tissue type, lesion depth, etc. are examples of some of the information that may be collected during the ablation process and used to help control ablation of the tissue.

This is achieved by locating the coil-locating device on a predetermined landmark on the patient's body. The coil and its signal wires can be incorporated into a stylet, guide wire or a catheter. The coil locating device can be orientated towards the head of the patient and for an axis of the device to be aligned with the mid sagittal plane of the patient.

Abstract: A three dimensional imaging system includes a first laser emitting light at a first wavelength, and a scanner for scanning the laser light in a pattern on the target area. A photo detector receives light reflected from the target area as a contrasted vein image, resulting from differential absorption and reflection therein of the first wavelength of light. The intensity of the first laser is incrementally increased, and the photo detector thereby receives a plurality of contrasted vein images, each being at incrementally distinct depths beneath the target skin surface. Image processing is performed on the plurality of vein images to successively layer the veins in the images according to their depth, to create a single processed vein image. A second laser emitting a second wavelength of light is used in combination with the scanner to project the processed vein image onto the target area to overlay the veins therein.
