Abstract:
1. An expandable medical device deployable at least partially within a tissue structure and adjacent a atrium of a heart, the expandable medical device comprising: a multi-cellular central frame portion configured to self expand from a first, non-tubular orientation to a second, non-tubular orientation, the first orientation being configured to fit within a catheter, the second orientation being configured to be deployed and operable within the tissue structure and adjacent the left atrium, said central frame portion comprising a plurality of interconnecting central frame support segments defining four cells, at least one of said central frame support segments having a length and a width, the width varying along at least a portion of the length; and at least one anchor linked to said multi-cellular central frame portion; wherein said plurality of interconnecting central frame support segments each include an arcuate portion extending along the length thereof, and each cell of said multi-cellular central frame portion is defined beat least four of said plurality of interconnecting central frame support segments such that each cell includes a common central frame support segment of an adjacent cell; and wherein said multi-cellular central frame portion, including said plurality of interconnecting central frame support segments and said at least one anchor, is a seamless, monolithic structure; and wherein said seamless, monolithic structure is substantially planar in the second non-tubular orientation.
