1. (A medical device comprising:
- a wire frame that includes a plurality of wires that each extends from a proximal end of the wire frame to a distal end of the wire frame and a sealing member attached to the wire frame, the plurality of wires and the sealing member forming;
a proximal eyelet at the proximal end of the wire frame, the proximal eyelet defined by proximal end portions of each of the plurality of wires converging from different locations about a longitudinal axis of the medical device;
a distal eyelet at the distal end of the wire frame, the distal eyelet defined by distal end portions of each of the plurality of wires converging from different locations about the longitudinal axis of the device;
a proximal disk adjacent the proximal eyelet and comprising a plurality of proximal petals;
wherein when viewed in a direction along the longitudinal axis in a deployed configuration of the medical device, each of the proximal petals includes two portions of the sealing member overlapping adjacent petals within the proximal disk and a portion of the sealing member non-overlapping the adjacent petals within the proximal disk to include a portion of each petal arranged toward the distal disk;
wherein the adjacent petals of the proximal disk are not interwoven with one another;
a distal disk adjacent the distal eyelet and comprising a plurality of distal petals;
wherein when viewed in a direction along the longitudinal axis in a deployed configuration of the medical device, each of the distal petals includes two portions of the sealing member overlapping adjacent petals within the distal disk and a portion of the sealing member portion non-overlapping the adjacent petals within the distal disk to include a portion of each petal arranged toward the proximal disk, and each of the plurality of wires form one of the proximal petals and one of the distal petals; and
a waist portion disposed between the proximal disk and the distal disk.

Abstract
The invention relates to a sealing device for repair of cardiac and vascular defects or tissue opening such as a patent foramen ovale (PFO) or shunt in the heart, the vascular system, etc. and particularly provides an occluder device and trans-catheter occluder delivery system. The sealing device would have improved conformity to heart anatomy and be easily deployed, repositioned, and retrieved at the opening site.
