Patent ID: 8083766

Claim:
A device for closing a septal defect of a patient having a first side and a second side, the device comprising: a fluid blocking covering patch having a proximal surface and a distal surface and a first non-expanded configuration for delivery and a second larger expanded configuration for placement on the first side of the defect, the covering patch composed of a first material having a dimension at least equal to a size of the defect to cover the defect and block fluid flow, the proximal surface of the patch engaging tissue on the first side of the defect the distal surface of the patch out of engagement with tissue; a support unattached to the covering patch and advanceable into the covering patch at the proximal end of the covering patch, the covering patch movable from the first configuration to the expanded configuration in response to receipt of the support therein; and first and second retaining legs extending proximally of the proximal surface of the patch to contact tissue on the second side of the defect to retain the covering patch, the first and second legs composed of a second material different than the first material and having a first reduced profile configuration for delivery and a second configuration for placement on the second side of the defect, the first and second retaining legs having free ends uncovered to directly engage tissue.
