A left atrial appendage occlusion device comprising: a deformable wire; and at least one anchor adapted to attach the device to left atrial appendage tissue; a sheet is attached to the wire; the deformable wire forms a first predetermined expanded shape and a second predetermined relaxed shape; the first predetermined expanded shape is substantially linear; the second predetermined relaxed shape is a substantially coiled shape, the substantially coiled shape comprising a plurality of wire orbits; characterized in that a length of the sheet is substantially greater than a width of the sheet when the wire forms the first predetermined expanded shape, the sheet extends along the wire in a flagged manner such that the length of the sheet extends in approximately the same direction as a longitudinal direction of the wire and the width of the sheet extends in about a normal direction from the longitudinal direction of the wire, when the deformable wire forms the second predetermined relaxed shape, overlapping sections of the sheet substantially eclipse an interior cross-section of the substantially coiled shape when viewing the substantially coiled shape along the shape's longitudinal axis. a deformable wire; and at least one anchor adapted to attach the device to left atrial appendage tissue; a sheet is attached to the wire; the deformable wire forms a first predetermined expanded shape and a second predetermined relaxed shape; the first predetermined expanded shape is substantially linear; the second predetermined relaxed shape is a substantially coiled shape, the substantially coiled shape comprising a plurality of wire orbits; a sheet is attached to the wire; the deformable wire forms a first predetermined expanded shape and a second predetermined relaxed shape; the first predetermined expanded shape is substantially linear; the second predetermined relaxed shape is a substantially coiled shape, the substantially coiled shape comprising a plurality of wire orbits; a length of the sheet is substantially greater than a width of the sheet when the wire forms the first predetermined expanded shape, the sheet extends along the wire in a flagged manner such that the length of the sheet extends in approximately the same direction as a longitudinal direction of the wire and the width of the sheet extends in about a normal direction from the longitudinal direction of the wire, when the deformable wire forms the second predetermined relaxed shape, overlapping sections of the sheet substantially eclipse an interior cross-section of the substantially coiled shape when viewing the substantially coiled shape along the shape's longitudinal axis. when the wire forms the first predetermined expanded shape, the sheet extends along the wire in a flagged manner such that the length of the sheet extends in approximately the same direction as a longitudinal direction of the wire and the width of the sheet extends in about a normal direction from the longitudinal direction of the wire, when the deformable wire forms the second predetermined relaxed shape, overlapping sections of the sheet substantially eclipse an interior cross-section of the substantially coiled shape when viewing the substantially coiled shape along the shape's longitudinal axis.
