  • Patent number: 7901359
    Abstract: A method and apparatus for improving blood flow to an ischemic region (e.g., myocardial ischemia) a patient is provided. An ultrasonic transducer is positioned proximate to the ischemic region. Ultrasonic energy is applied at a frequency at or above 1 MHz to create one or more thermal lesions in the ischemic region of the myocardium. The thermal lesions can have a gradient of sizes. The ultrasound transducer can have a curved shape so that ultrasound energy emitted by the transducer converges to a site within the myocardium, to create a thermal lesion without injuring the epicardium or endocardium.

  • Publication number: 20070083193
    Abstract: Devices, systems and methods are disclosed for the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be constrained within the lumen of a catheter, and deployed to take on an expanded condition. The carrier assembly includes multiple electrodes that are configured to ablate tissue at low power. Systems include an interface unit with a visual display that provides a visual representation of the geometry of the ablation elements and/or provides selection means for selecting an icon provided on the display.

  • Patent number: 7070594
    Abstract: Systems and methods for assessing the formation of an ice ball during a cryoablation procedure are disclosed. The system includes a reference electrode that is placed in contact with the patient and a cryocatheter having a cryotip. An electronic circuit is connected to both the cryotip and the reference electrode to measure the impedance therebetween which can be used to assess the formation of an ice ball during a cryoablation procedure. An exemplary measurement signal has a frequency of approximately 20 khz and an RMS voltage of approximately 0.5V. With the cryotip positioned proximate the target tissue, a reference impedance is measured. Next, the conductive tip member is placed in contact with the target tissue and cooled to form an ice ball. During cooling, impedance measurement(s) are taken and compared with the reference impedance to assess the formation of the ice ball.

  • Publication number: 20060106375
    Abstract: Devices, systems and methods are disclosed for the ablation of tissue and treatment of cardiac arrhythmia. An ablation system includes an ablation catheter that has an array of ablation elements and a location element, an esophageal probe also including a location element, and an interface unit that provides energy to the ablation catheter. The distance between the location elements, determined by calculating means of the system, can be used by the system to set or modify one or more system parameters.
