Abstract: Devices, systems, and methods for performing ablation therapy on body tissue are disclosed. An example ablation device for treating body tissue includes an ionically conductive balloon and a radio-frequency electrode that delivers RF energy into a distal section of the balloon. The balloon is configured to transmit the RF energy in a direction distally towards a leading end of the ablation device. Multiple ablation electrodes on the device can be used for providing lesions of different size or shape.

Abstract: Various embodiments concern sensing a first signal indicative of a plurality of different phases of a cardiac cycle with a sensor and sensing a second signal with an ultrasound sensor within the heart over different phases, the second signal indicative of the density of a section of cardiac tissue. Each phase can be associated with an indication of the density of the section of cardiac tissue during the phase based on the second signal. It can be determined whether the section of cardiac tissue compressed during the cardiac cycle based on a change in the indication of density of the cardiac tissue over the plurality of different phases. The efficacy of ablation therapy can be evaluated based on the compressibility of the section of cardiac tissue.

Abstract: The present invention relates to a device for the prevention of air embolisms during a catheterization procedure. The device includes a bulb element configured to secure to a sheath assembly. The bulb element includes a flexible wall, including a proximal section and a distal section, and an interior chamber in fluid communication with a pressurized fluid source. The proximal section of the bulb element includes a proximal hub, and the distal section of the bulb element includes a distal hub. The bulb element is collapsible, under the action of an external force, from a first, relaxed state in which the interior chamber has a first volume, to a second, collapsed state in which the interior chamber has a second volume less than the first volume, and wherein the bulb element is configured to assume its first, relaxed state in the absence of the external force.
