摘要： A cardiac ablation instrument capable of removing blood from a treatment area is provided. The instrument includes a catheter configured to deliver a distal end thereof to a patient's heart. The instrument can also include an expandable element coupled to the distal end of the catheter wherein the expandable member is configured to be positioned adjacent a target area thereby defining a treatment area between the expandable member and the target area. Further, the instrument can include an irrigation mechanism configured to dispense an irrigation fluid from the catheter thereby displacing blood from the treatment area. Additionally, the instrument includes an energy emitter configured to deliver energy to tissue within the treatment area. The instrument can also include a contact sensor configured to determine the presence of such blood within the treatment area. Methods for ablating tissue are also provided.

摘要： An apparatus and method for phototherapy are described in which laser light or other radiation is projected from within a catheter, through a balloon member, and toward the surface of tissue. The light reflected from body fluids or the tissue surface is captured by a collecting device located within the catheter, e.g., within the balloon member, and the intensity of the reflected light is ascertained. The apparatus and method provides for accurately positioning the apparatus against the tissue treatment site.

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 to form a series of lesions on the target tissue.

摘要： Methods and apparatus are disclosed for forming annular lesions in tissue. The methods include introduction of an optical apparatus proximate to a tissue site, via, for example, a catheter. The optical apparatus includes a pattern-forming optical wave guide in communication with a light transmitting optical fiber. Energy is transmitted through the optical fiber, such that radiation is propagated through the optical fiber and the wave guide projects an annular light pattern, e.g., a circle or a halo.
