    摘要： A system, device, and method for the treatment of cardiac arrhythmia by, specifically, cryolipolysis of non-myocardial tissue and cryoablation of myocardial tissue. A system for treating cardiac arrhythmia may include a first thermal treatment device configured for placement within a heart in contact with myocardial tissue, a second thermal treatment device configured for placement in contact with pericardial tissue, an ablation energy source in communication with the first thermal treatment device, and a cooling energy source in communication with the second thermal treatment device, the cooling energy source causing the second thermal treatment device to reach a temperature insufficient for myocardial ablation when the second thermal treatment device is activated. A method of treating cardiac arrhythmia may include introducing a cooling element into a pericardial space proximate pericardial adipose tissue, and activating the cooling element to reduce the temperature of adjacent pericardial adipose tissue to approximately 0° C.

    摘要： Neuromodulation cryotherapeutic devices and associated systems and methods are disclosed herein. A cryotherapeutic device configured in accordance with a particular embodiment includes an elongated shaft and a cooling assembly at distal portion of the shaft. The shaft can be configured to locate the distal portion intravascularly at a treatment site within or otherwise proximate a renal artery. The cryotherapeutic device can further include a supply lumen configured to carry liquid refrigerant toward the cooling assembly. The cooling assembly can include an applicator in fluid communication with the supply lumen and configured to deliver cryotherapeutic cooling to nerves proximate the target site when in a deployed state.

    摘要： A device and system for thermally affecting tissue that includes a balloon catheter with a reduced distal length for ease of navigation and that also includes a balloon that is more resistant to bursting and delamination. The balloon may include a proximal neck generally attached to an elongate body and a distal neck generally attached to a shaft disposed within the elongate body. The distal neck is turned inward to extend within the balloon chamber and the proximal neck may either extend within the chamber or extend proximally away from the balloon chamber. Alternatively, the device may include an inner balloon and an outer balloon, the distal necks of both being turned inward and extending within the inner balloon chamber. The proximal necks may both also be turned inward to extend within the chamber or the proximal neck of the outer balloon may extend away from the balloon chamber.

    摘要： A surgical cutting tool includes a catheter, a first diametrically expandable member such as an inflatable balloon at a first location on the catheter, a second diametrically expandable member such as an inflatable balloon at a second location on the catheter that is distally spaced from the first expandable member, a cutting tool such as a cauterization tip extending between the first and second expandable members, and expanding structure such as a lumen for enabling the first and second expandable members to be actuated between a reduced diameter state and an expanded diameter state, and thereby move and position the cutting tool radially with respect to the catheter.
