Interseptal occluder device

An occluder device comprising:

• a supporting structure, said supporting structure comprising a central portion having a distal end and a proximal end;
• said supporting structure comprising distal branches extending away from said distal end of the central portion;
• said supporting structure comprising proximal branches extending away from said proximal end of the central portion;
• said proximal branches and distal branches being bendable to anchor the occluder device in a septum of a heart;
• said occluder device further comprising at least one membrane;
• said at least one membrane comprises a membrane body connected to at least one of the distal branches or the proximal branches;
• when the distal branches and the proximal branches are in an unfolded or lying position, said at least one membrane has a closed position where the at least one membrane is in a configuration which provides maximum occlusion to the supporting structure;
• and
• said at least one membrane comprising at least one slit, which, when actively engaged by an external device the at least one membrane deforms the at least one slit which extends elastically, creating a passage lumen for said external device, wherein the at least one slit is spaced from the central portion and is located between a pair of adjacent branches of the proximal branches or the distal branches of which the at least one membrane is connected to, such that, when actively engaged by said external device, the external device crosses the at least one membrane outside the central portion.
