Abstract
Methods and devices for increasing flow in the left atrial appendage (LAA) include a conduit directing blood flow from a pulmonary artery into the LAA and/or a conduit drawing blood from the LAA by a Bernoulli effect. In one embodiment, a method comprises implanting a conduit in a pulmonary vein, expanding an inlet portion such that the conduit becomes anchored within the vein and directs blood through an outlet portion of the conduit into or toward the left atrial appendage.
Claims15
A prosthetic conduit configured to be implanted into a cardiac structure, comprising:
- a radially collapsible and expandable tubular body defining a lumen, the tubular body including an inlet portion and an outlet portion, the inlet portion configured to be anchored in a pulmonary vein;
- wherein the prosthetic conduit has an elongate shape configured such that the outlet portion is spaced apart from an ostium of the pulmonary vein when the prosthetic conduit is implanted in the pulmonary vein, and wherein the tubular body, when expanded, is biased toward a curved shape such that the prosthetic conduit is adapted to direct a flow of blood from the pulmonary vein through the lumen of the prosthetic conduit and outwardly through the outlet portion in a direction toward a left atrial appendage when the prosthetic conduit is implanted in the pulmonary vein;
- and
- wherein the tubular body is configured such that the lumen of the prosthetic conduit remains in an open configuration throughout its length once implanted in the pulmonary vein.
