    摘要: An apparatus and method for treating a cardiac condition with visual inspection of a tissue treatment site includes the step of delivering an expanding member formed on a distal end of a catheter to a position adjacent a tissue treatment area within a patient's heart. The expandable member has an elastic portion configured to conform to the tissue treatment area. The method further includes the steps of expanding the expandable member thereby allowing the elastic portion of the expandable member to conform to the tissue treatment area and positioning an energy emitter at a first location within an inner lumen of the catheter. A visible aiming beam is projected during positioning of the energy emitter and ablative energy is delivered from the energy emitter to the tissue treatment area thereby resulting in a first spot lesion. The ablative energy is coincident with the aiming beam and the aiming beam is in the form of pulsed visible light to allow intermittent visual inspection of the first spot lesion at times when the aiming beam is not projected onto the tissue treatment area, thereby allowing visual inspection of the ablative characteristics and sufficiency of the first spot lesion.

    摘要: Various types of body heating or cooling devices are described in the present disclosure. Such devices, and associated methods, can utilize two separated thermal transfer fluids to promote heating or cooling of a body part. For example, a cooling cap can include a rigid shell and a flexible seal that form a fluid containment space with a patient's head. The rigid shell can include a fluid circulation apparatus disposed within the fluid containment space, and be coupled to a console pump to form a closed loop circulation system. A volume of fluid can be introduced into the fluid containment space to contact the patient's scalp. The console pump can then circulate a thermal transfer fluid through the fluid circulation apparatus to reduce the temperature of a fluid held within the fluid containment space.

    摘要: An elongate tubular body is disclosed, such as for use in medical applications. The body comprises a spring coil having at least one central lumen extending axially therethrough, for receiving medical implements, fiber optics, suction or transmission of fluids such as for irrigation or drug delivery. An elastomeric outer layer on the spring coil provides a substantially water impermeable seal. A distal tip may be integrally formed with the elastomeric outer layer.

    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.
