  • Publication number: 20140276771
    Abstract: The invention describes methods for safely delivering ablation energy to a tissue, e.g., thrombus, in need of ablation therapy. The method uses a catheter adapted for IVUS imaging, ablation, and impedance measurements to monitor the impedance of a tissue receiving ablation energy. In an embodiment, a user may view an IVUS image of the tissue with impedance measurements to determine if it is safe to deliver additional energy. In another embodiment, a processor is configured to determine if it is safe to deliver additional ablation energy based upon the impedance measurement.

  • Publication number: 20130231558
    Abstract: A system and method are provided for significantly reducing or substantially eliminating angular geometric distortions in devices designed for imaging and/or inspection of an interior portion or surface of a cavity. A series of processing steps or methods may be employed to eliminate Non-Uniform Rotational Distortion (NURD) in such devices, for example, unidirectional and bi-directional intravascular ultrasonic (IVUS) imaging systems. The system may include a processor and an electronic module which control operation of a transducer assembly provided at a distal end of a catheter assembly. The system invokes a first processing step or method to collect and store raw angle and line data, as well as one or more of second and third processing steps or methods which adjust for NURD experienced during backlash of a bi-directional imaging system and a fourth processing step or method which performs a line-to-line correlation function.

  • Publication number: 20040249264
    Abstract: A trigger generator for supplying a trigger signal to a medical device. The generator includes a respiratory signal device associated with the subject that generates a respiratory signal representing the flow of gas into and out of the subject's lungs during the subject's breathing cycle. A trigger generator integrates the respiratory signal and generates a trigger signal when the integrated respiratory signal has a value representing a selected point in the subject's breathing cycle.

  • Patent number: 6552796
    Abstract: Methods and apparatuses are provided for performing optical imaging on a sample. The method and apparatuses continually adjust the path-length of a reference arm or data acquisition in a manner such that imaging information is obtained only from a longitudinal range that contains a selective portion of a sample from which imaging information is to be obtained. The apparatuses include a starting point adjustment device that determines a point with respect to a sample at which imaging information collection is to be started. A controller then controls a second scanning mechanism, in addition to a first scanning mechanism, such that imaging information is obtained only from a longitudinal range that contains a selective portion of a sample from which imaging information is to be obtained. In this way, the amount of data collected can be reduced to that within the area of interest.
