Abstract:
1. A containment device for positioning at a left atrial appendage, comprising: a proximal end, a distal end, an intermediate portion between the proximal and distal ends, and a longitudinal axis extending therethrough; at least three supports extending between the proximal end and the distal end; each support comprising an elongate, flexible element which is movable from a first orientation in which the element extends substantially parallel to the axis at no more than a first distance from the axis, to a second orientation in which at least a portion of the element is inclined toward the intermediate portion with respect to the axis and is separated by at least a second distance from the axis which is greater than the first distance, wherein the intermediate portion in the second orientation is sized and configured to engage a surface at the left atrial appendage and the supports in their second orientation increase radially in dimension from the proximal end to an apex portion and then decrease radially in dimension from the apex portion to the distal end; and an endothelialization membrane carried by the device, for promoting endothelialization across the left atrial appendage, wherein the endothelialization membrane at least in part comprises a first membrane on a first side of the supports, a second membrane on a second side of the supports, and a bonding layer for bonding the first membrane and the second membrane together.
