Abstract:
1. An occluder device for closing two overlapping layers of septum primum and septum secundum dividing a left atrium and a right atrium in a mammalian heart, comprising: first and second opposed closure members configured to be disposed on opposite sides of the septum, each of said closure members generally defining a plane with a periphery, wherein the planes are configured to be generally parallel to each of septum primum and septum secundum; and a center joint connecting the first and second opposed closure members, the center joint comprising pairs of parallel wire paths and at least two collars having first and second opposing ends, wherein each wire path begins at the first end of a first collar and terminates at a first end of a second collar, wherein further each wire path forms a center vertex between the collars; wherein the center joint is configured so the center vertex of each wire path extends between the overlapping layers of septum primum and septum secundum leaving the collars and closure members outside the layers, wherein further at least one of said closure members has a generally heart shape and includes two lobes that come together at the center joint, the lobes having contact points at adjacent corners to provide a compressive force to the overlapping layers of septum primum and septum secundum wherein said closure members are configured to prevent the device from moving along a longitudinal axis formed by the passage between septum primum and septum secundum when the device is deployed.
