Described here are devices, systems and methods for forming a fistula between two blood vessels. Generally, the systems may comprise a first catheter which may comprise a fistula-forming element. The fistula-forming element may comprise one or more electrodes, mechanical cutting elements, laser sources, or combinations thereof, and may be used to assist in fistula formation. In some instances, a system may comprise a second catheter, which may comprise a fistula-forming element. One or more of the catheters may comprise one or more markers, magnetic alignment elements, and/or one shape-changing elements.

Devices and methods for forming a fistula

Described here are devices for closing one or more tissues, and handles for controlling these devices. Generally, the devices described here comprise a snare loop assembly, wherein the snare loop assembly comprises a snare and a suture loop, and a handle for controlling the snare loop assembly. In some variations the snare loop assembly may comprise a retention member that may releasably connect the suture loop to the snare. In other variations the devices comprise one or more force-reducing suture locks to help prevent the suture loop from inadvertently disengaging from the snare loop assembly. In still other variations, the excess-suture management features. The handles described here may be configured to remove excess suture from a suture loop, and may also be configured to release the suture loop from the snare loop assembly.

Tissue ligation devices and controls therefor

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 therethrough.
