    摘要: 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.

    摘要: A transducer subassembly with combined imaging and therapeutic capabilities is disclosed. The subassembly includes heat sinks that are configured to maintain the transducer at a low operating temperature so that the transducer operates at high efficiency and also can handle a wider range of frequencies. The subassembly is also configured to allow cooling fluid to flow past the transducer element. One heat sink in the subassembly also acts as an acoustic matching layer and another heat sink acts as a backing Alternatively, the second heat sink which acts as a backing is optional. The transducer is configured to transmit at one power level for imaging, and at a second power level for ablating. The transducer may comprise sub-elements transmitting at different power levels. The subassembly may be operated at one power level for imaging and a second power level for ablating.

    摘要: A method of mapping tissue includes sensing a first region and a second region of a chamber of body tissue. The sensing includes moving an ultrasound transducer of a catheter over a surface of the region along a sensing pattern, and using the ultrasound transducer to gather a set of echo-anatomical data in an amplitude mode at a plurality of points along the sensing pattern. The set of echo-anatomical data comprises distances between the ultrasound transducer and the surface at the plurality of points. A three-dimensional surface map is generated using the set of echo-anatomical data from each region. The surface maps of the regions are combined to form a combined surface map. Methods also include using a set of echo-anatomical data to generate a three-dimensional surface map of a region, from a detected border of the body tissue and detected motion phases of the region.
