Abstract
A medical device, system and method for modifying a left atrial appendage (“LAA”). The medical device system includes a tether anchored within the LAA and one or more tissue growth members or occluders configured to be slid over the tether and lodged within the LAA. With this arrangement, a physician may close-off the LAA with a selective number of tissue growth members to meet the varying LAA sizes as determined from imaging information while conducting the procedure.
