    摘要: Apparatus and methods for performing cryogenic ablation of tissue and adjusting the size and/or location of a cryogenic cooling region. A cooling assembly may include tubes for dispensing and exhausting a coolant or refrigerant. One or both of the tubes may be moved, e.g., slidably adjusted, in order to adjust the location or size of a cryogenic ablation region. The cooling assembly may be integrated into cryogenic ablation devices including a cryogenic balloon device that includes an inner inflatable balloon and another balloon that is at least partially wrapped around the inner balloon and carries refrigerant for performing cryo-ablation. Electrodes permit electrical mapping of tissue before or after cryo-ablation to verify success of the procedure.

    摘要: The present inventions provide assemblies, probes, and methods for creating circumferential lesions in tissue, e.g., the tissue within or around the ostium of a vessel. An ablation probe with an ablative structure can be placed in contact within or around the ostium of the vessel. A diagnostic probe can be introduced through a lumen within the ablation probe and inserted into the vessel. The energy can be provided to the ablative structure to create a circumferential lesion within or around the ostium of the vessel, and the diagnostic structure can be used to diagnose the tissue to determine whether the circumferential lesion can be properly created.

    摘要: A deflectable catheter for ablating tissue in the heart of a patient comprising: an axially elongated catheter shaft sized and constructed to be advanced through the vasculature of a patient into the patient's heart; a deflection wire; and an ablation electrode having first and second opposed electrically conductive surfaces exposable for contact with a selected area of tissue within the patient's heart and movable with respect to each other to apply gripping force to the contacted area of heart tissue for stabilizing the position of the electrically conductive surfaces of the ablation electrode relative to the selected area of heart tissue. The ablation electrode has a first rigid surface exposed for contact with the vasculature of the patient during advancement of the catheter therethrough and has an electrically conductive second rigid surface exposable for contact with a selected area of tissue within the patient's heart, wherein the axially transverse area circumscribed by the first surface of the ablation electrode is less than the tissue-contacting area exposable by the second rigid surface. Therapeutic treatments of the heart of a patient are also disclosed.
