摘要： A medical delivery system for delivering a fluid to a desired location within a body that includes a first member having an aperture, and a second member adapted to be positioned over the first member. The fluid to be delivered is contained within a fluid storage device, formed by at least one of the first member and the second member. The medical delivery system includes means for repositioning the first member relative to the second member between a first state preventing passage of the fluid through the aperture and a second state enabling passage of the fluid outward from the fluid storage device through the aperture.

摘要： A catheter body of a catheter assembly includes a proximal portion, an intermediate portion extending from the proximal portion, a distal portion extending from the intermediate portion, and a locating device including a distal tip extending from the distal portion of the catheter body. The intermediate portion defines a longitudinal axis and the distal portion forms a loop including one or more loop segments formed around a central loop axis. The central loop axis is substantially parallel with the longitudinal axis and the one or more loop segments include at least one ablation electrode coupled thereto and adapted to create a lesion, the lesion electrically isolating a vessel from a chamber for treatment of a cardiac arrhythmia. The distal tip of the locating device is substantially parallel with the central loop axis.

摘要： A method and apparatus for treating atrial tachyarrhythmias, particularly atrial fibrillation. High energy pulses are delivered between electrodes located in the right atrium/SVC, the left pectoral region and the coronary sinus/great vein, with the left pectoral and coronary sinus/great vein electrodes connected in common. Optionally a ventricular electrode may also be employed in conjunction with one or more of the other listed electrodes to accomplish ventricular cardioversion or defibrillation.

摘要： In an implantable pacemaker/cardioverter/defibrillator, a system for correlating the delivery of a cardioversion therapy to an optimum point or phase of the respiratory cycle of the patient to effect delivery of the therapy when the impedance between the cardioversion electrodes is minimized. In a first application for use with cardioversion electrodes located substantially in contact with the heart chamber, the optimum point or phase is at the end of inspiration. In a second application for use with at least one cardioversion electrode located remotely from the heart chamber, the optimum point or phase is at end expiration or beginning of inspiration. The cardioversion therapy is delivered in synchrony with a ventricular sense event, if present. If the optimum point or phase of the respiratory cycle cannot be determined during a therapy time, a pre-shock may be delivered to elicit a respiration cycle through a stimulated contraction of the diaphragm.

摘要： A catheter assembly and method for treatment of cardiac arrhythmia, for example, atrial fibrillation, by electrically isolating a vessel, such as a pulmonary vein, from a chamber, such as the left atrium. The catheter assembly includes a catheter body and at least one electrode. The catheter body includes a proximal portion, an intermediate portion and a distal portion. The intermediate portion extends from the proximal portion and defines a longitudinal axis. The distal portion extends from the intermediate portion and forms a substantially closed loop transverse to the longitudinal axis. The at least one electrode is disposed along the loop. With this configuration, the loop is axially directed into contact with the chamber wall about the vessel ostium. Upon energization, the electrode ablates a continuous lesion pattern about the vessel ostium, thereby electrically isolating the vessel from the chamber.
