Systems and method for left atrial appendage obliteration

Abstract

Various aspects and embodiments solve at least some of the problems associated with conventional LAA closure approaches. Example devices and methods are disclosed for closing the LAA that can be used under direct visual guidance and in a short time period. Various embodiments employ a transesophageal barrier to provide a sealable opening through a patient's esophagus. The sealable opening allows surgical devices and in particular LAA closure devices to pass through the patient's esophagus into the patient's thoracic cavity. In one embodiment, an LAA closure device includes a snare wire having engagement members for maintaining and/or decreasing a circumference of a loop of the snare wire. The loop of the snare wire can be used like a noose to strangle the LAA to achieve closure. In other examples, wire traction devices can be used to close or obliterate the LAA.
