    摘要： An ablation catheter that includes a shaft having a distal end and a balloon coupled to the shaft. The balloon has an inner surface and an opposite outer surface. The inner surface has a proximal region including a proximal balloon end, a main center region, and a distal region including a distal balloon end. The ablation catheter also includes an energy emitter disposed inside the balloon and being configured to move both axially and rotationally within the inside of the balloon. The ablation catheter includes a thermally resistant coating disposed along the inner surface of the balloon within at least the main center region of the inner surface of the balloon. The thermally resistant coating is formed of a material selected from a group consisting of: silicone rubber, polyisoprene, polyurethane.

    摘要： Guided ablation instruments are disclosed for creating lesions in tissue, especially cardiac tissue for treatment of arrhythmias, including atrial fibrillation. In one aspect of the invention, a percutaneous catheter is disclosed with an endoscope positionable in the instrument's distal end region to obtain an image. The image allows the clinician to determine whether contact has been achieved (or blood has been cleared from an ablative energy transmission path) before ablation begins or while ablation is occurring. In one embodiment, percutaneous ablation catheters are disclosed having at least one central lumen and one or more balloon structures at the distal end region of the instrument. Also disposed in the distal end region are an illuminating light source and an endoscope capable of collecting sufficient light to relay an image to the user. The instruments can further include an ablation element. The ablation element can be a contact ablation element, or a radiant energy emitter, which is preferably independently positionable within the lumen of the instrument and adapted to project ablative energy through a transmissive region of the instrument body (and/or balloon) to a target tissue site proximate to the pulmonary veins. The energy can delivered without the need for contact between the energy emitter and the target tissue so long as a clear transmission pathway is established. The endoscope element of the instrument allows the clinician to determine the position of the instrument and, if radiant energy is to be employed, see if such a pathway is clear. Moreover, because the position of the radiant energy emitter can be varied, endoscopic guidance permits the clinician to select a desired location and dose for the lesion.

    摘要： The present disclosure relates to ablation instruments and methods of use thereof, in particular to ablation catheters and methods for an automated sweeping ablation element. The automated sweeping ablation element is configured to provide ablative energy to an initial ablation site and move a predetermined number of degrees to one or both sides of the site in an arcuate path using a sweeping motion while still providing the ablative energy. The sweeping movement of the ablation element can be automated via input parameters entered by a user via a graphical user interface or other device (controller).

    摘要： A system is provided for identifying the sufficiency of lesions formed during a tissue ablation procedure. The system and method include administering an ICG composition to the patient and forming one or more lesions at a surgical site. The method further includes applying energy of a type and in an amount sufficient to cause ICG in the patient to fluoresce. An image of the tissue and lesion at the surgical site is obtained while the ICG fluoresces. The lesion is distinguished from surrounding de novo tissue based on areas of fluorescence to allow a user to evaluate the quality of the lesion.

    摘要： Malleable surgical ablation instruments are disclosed for creating lesions in tissue, including cardiac tissue for treatment of arrhythmias and other diseases. The hand held instruments are especially useful in open chest or port access cardiac surgery for rapid and efficient creation of curvilinear lesions to serve as conduction blocks. The malleable instruments disclosed are well adapted for use in or around the intricate structures of the heart. In one example, the distal end of the instrument can have a malleable shape or be in the shape of an open loop so as to allow the loop to be placed around at least one a pulmonary vein or artery. Such instruments can incorporate various ablative elements such as ablative radiation, RF heating, cryogenic cooling, ultrasound, microwave, ablative fluid injection and the like.
