Problems solved by technology

[0006] Likewise, if AF occurs, simple remodeling or dilation of the LAA is ineffective in preventing flow stagnation, since the lack of atrial contraction still limits the amount of blood flow through the LAA

Abstract

The invention relates to a device and method for increasing flow through the left atrial appendage. 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.

Description

[0001] This application is a divisional application, the filing date of the original application is March 21, 2014, the application number is 2014800170710 (PCT / US2014 / 031505), and the title of the invention is "equipment and method for increasing flow through the left atrial appendage". [0002] This application claims the benefit of U.S. Patent Application No. 61 / 804,518, filed March 22, 2013, and U.S. Patent Application No. 14 / 220,929, filed March 20, 2014, both of which are hereby incorporated by reference in their entirety This article. technical field [0003] The present invention relates to devices and methods for increasing flow through the left atrial appendage of the human heart, thereby helping to prevent flow stagnation in the left atrial appendage. Background technique [0004] Cardiac arrhythmias are abnormal heart rhythms that make the heart pump blood more efficiently. Atrial fibrillation (AF) is one of the most common cardiac arrhythmia conditions. AF mak...
