Abstract
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.
