摘要： Described here are devices, systems and methods for closing the left atrial appendage. Some of the methods described here utilize one or more guide members having alignment members to aid in positioning of a closure device. In general, these methods include advancing a first guide having a first alignment member into the left atrial appendage, advancing a second guide, having a second alignment member, into the pericardial space, aligning the first and second alignment members, advancing a left atrial appendage closure device into the pericardial space and adjacent to the left atrial appendage, and closing the left atrial appendage with the closure device. In these variations, the closure device typically has an elongate body having a proximal end and a distal end, and a closure element at least partially housed within the elongate body. The closure element comprises a loop defining a continuous aperture.

摘要： A catheter having expandable electrodes for applying energy to a hollow anatomical structure such as a vein. When used on a vein, the catheter is useful for a minimally invasive treatment of venous insufficiency. The catheter includes conductive end rings to which the electrodes are attached, for mechanically connecting and electrically tying electrodes together to provide for a single wire electrical connection points, for transmitting energy while more evenly spacing the electrodes. Expandable arms are formed of electrically conductive material and insulated along their length except for an intermediate section that functions as the electrode. The arms are tapered to allow more room for wiring and to reduce the possibility of shorting between the ends of the arms. The catheter further includes thermocouples in the electrodes for measuring temperatures on the outer surface of the electrode. Slots are formed in the arms for mounting the thermocouples. The temperature at the hollow anatomical structure is monitored and if a rapid, large temperature decrease of short duration is noted, the power is maintained constant as a fluid flush has been detected.

摘要： A test system and method for evaluating the efficiency of the venous pump in leg muscles and for identifying incompetent venous valves. The test system comprises a legging having inflatable bladders, a manifold and a system controller. A pressurized inflation source is provided which is in fluid communication with the manifold and the legging. The controller sequences valves within the manifold to inflate and deflate the bladders of the legging. The test system further includes a Doppler blood flow sensor interfaced to the controller. The sensor is configured with a housing which contains a rotatable disk, upon which two pairs of crystals are disposed. The sensor housing is secured a leg of a patient proximate a blood vessel in which blood flow is to be measured. The patient is positioned on a reclinable test station, upon which the controller and manifold may be mounted. The maximum volume of venous blood output from the leg is measured and the venous output flow is subsequently measured after the bladders are sequentially inflated above a first location on the leg of the patient. Reduced venous output flow from the maximum volume output indicates reflux and identifies the location of an incompetent valve.
