Claim Text:
1. A method of implanting an expandable intracardiac cage into a left atrium of a heart, comprising: advancing intravascularly a delivery sheath having a sheath proximal end, a sheath distal end, and a lumen extending therebetween to a right atrium of a heart; advancing the delivery sheath distal end through an opening between the right atrium and the left atrium wherein the sheath distal end contains an expandable cage having a proximal end, a distal end, and a plurality of supports extending therebetween, wherein the expandable cage has a collapsed configuration sized and adapted to be received within the lumen of the sheath distal end, and an expanded configuration for deployment within the heart; delivering the expandable cage to the left atrium through the delivery sheath; and expanding the expandable cage within the left atrium, the expandable cage when expanded positioning one end of the expandable cage at an ostium of the left atrium; positioning the remaining end of the expandable cage at an opposed wall of the left atrium, wherein the cage includes a plurality of tissue engaging anchors proximate at least one of the distal end or the proximal end of the cage such that at least a majority of the plurality of supports has at least one tissue engaging anchor fixedly attached thereto, wherein the cage is sized and adapted to span the distance between opposed walls of the left atrium to maintain a degree of residual compression of the cage while contacting the opposed walls of the left atrium.
