    摘要： 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.

    摘要： Surgical and percutaneous devices for closing tissue, for example, the left atrial appendage, may have an elongate body with a stiffened proximal portion, a flexible middle portion, a distal portion, a closure element with a loop having a continuous aperture therethrough, and a suture loop. The closure devices may have a malleable member attached to the elongate body that may be configured to retain a curve after a force is applied to the malleable member. System and methods for closing the left atrial appendage may utilize a closure device and a curved guide device, and the closure device and curved guide device may be self-orienting.

    摘要： Tissue stabilizing devices and methods for stabilizing, and optionally closing, a target tissue, such as the left atrial appendage, generally include an elongate body with a first lumen and a second lumen, a suction tip coupled to the elongate body, and an injection tip coupled to the elongate body proximal of the suction tip. The suction tip may define a suction aperture and the suction aperture may be in fluid communication with the first lumen to apply suction to the target tissue. The injection tip may be in fluid communication with the second lumen to dispense a contrast fluid.
