摘要： An enhanced method and device are provided to treat atrial fibrillation or inhibit or reduce restenosis following angioplasty or stent placement. A balloon-tipped catheter is disposed in the area treated or opened through balloon angioplasty immediately following angioplasty. The balloon, which can have a dual balloon structure, may be delivered through a guiding catheter and over a guidewire already in place. A fluid such as a perfluorocarbon flows into the balloon to freeze the tissue adjacent the balloon, this cooling being associated with reduction of restenosis. A similar catheter may be used to reduce atrial fibrillation by inserting and inflating the balloon such that an exterior surface of the balloon contacts at least a partial circumference of the portion of the pulmonary vein adjacent the left atrium. In another embodiment, blood perfusion is performed simultaneously. In another embodiment, tissue contacted by the cryoablation catheter, undesired to be ablated, is protected against damage by a separate heating step.

摘要： Apparatus for sealing vascular penetrations comprise a shaft having an electrode or other energy-applying element at a distal end. The shaft is placed in a tissue tract over a blood vessel penetration and located using a locator which engages an inner wall of the blood vessel. Once in position, an anchor is used to hold the shaft, allowing the locator to be removed. Energy is then applied through a distal tip of the shaft in order to induce desiccation and plug formation in a blood pool formed between the distal end of the shaft and the wall of the blood vessel.

摘要： A high-frequency heating electrode 3 and a temperature sensor 4 are disposed within a balloon 2 attached to a distal end portion of a catheter main body 1. With the balloon 2 being in abutment with a pulmonary vein opening 12a, a heating liquid within the balloon 2 is heated by the electrode 3, whereby the pulmonary vain opening 12a is annularly cauterized. A reservoir 41 is connected to a connector 20 which is connected to a proximal end portion of the catheter main body 1. By reciprocally driving a diaphragm 42 of the reservoir 41 by a motor 43, a heating liquid within the reservoir 41 is vibrated, and the vibrations are transmitted to the heating liquid within the balloon 2 via a heating liquid within the connector 20 and a heating liquid within the catheter main body 1. While the heating liquid heated to a high temperature by the electrode 3 attempts to rise to gather at an upper portion within the balloon 2, since the heating liquid within the balloon 2 is stirred by the vibrations, the balloon 2 is heated uniformly.

摘要： Ablation methods and instruments are disclosed for creating lesions in tissue, especially cardiac tissue for treatment of arrhythmias and the like. Percutaneous ablation instruments in the form of coaxial catheter bodies are disclosed having at least one central lumen therein and having one or more balloon structures at the distal end region of the instrument. The instruments include an energy emitting element which is independently positionable within the lumen of the instrument and adapted to project radiant energy through a transmissive region of a projection balloon to a target tissue site. The instrument can optionally include at least one expandable anchor balloon disposed about, or incorporated into an inner catheter body designed to be slid over a guidewire. This anchor balloon can serve to position the device within a lumen, such as a pulmonary vein. A projection balloon structure is also disclosed that can be slid over the first (anchor balloon) catheter body and inflated within the heart, to define a staging from which to project radiant energy. An ablative fluid can also be employed outside of the instrument (e.g., between the balloon and the target region) to ensure efficient transmission of the radiant energy when the instrument is deployed. In another aspect of the invention, generally applicable to a wide range of cardiac ablation instruments, mechanisms are disclosed for determining whether the instrument has been properly seated within the heart, e.g., whether the device is in contact with a pulmonary vein and/or the atrial surface, in order to form a lesion by heating, cooling or projecting energy. This contact-sensing feature can be implemented by an illumination source situated within the instrument and an optical detector that monitors the level of reflected light. Measurements of the reflected light (or wavelengths of the reflected light) can thus be used to determine whether contact has been achieved and whether such contact is continuous over a desired ablation path.
