1. A device for occluding an appendage inside a living body forming an elongate passage and having an open entrance and a hollow interior, comprising:
at least one elongate resilient tube formed of a mesh of shape memory alloy, the at least one tube compressible to be delivered to the appendage within a catheter, the at least one tube self-expanding as the at least one tube is released from the catheter to contiguously form, sequentially:
an outer perimeter structure
that is elongate on a side portion of the outer perimeter structure to be sized and dimensioned to flexibly conform to a longitudinal anatomy of an interior surface of the appendage extending along a longitudinal axis of the appendage when the device is deployed within the appendage;
an inner perimeter structure
sized and dimensioned along an elongate contact area to flexibly and conformingly contact and abut an interior of the outer perimeter structure along the longitudinal anatomy to thereby mutually conform to interior surface of the appendage together with the outer perimeter structure when the device is deployed within the appendage,
the inner perimeter structure thereby frictionally engaging the outer perimeter structure along the elongate contact area to thereby resist displacement of the outer perimeter structure along the longitudinal axis of the appendage, the inner perimeter structure and the outer perimeter structure thereby together forming a single double-walled perimeter structure defining a hollow interior;
a double-walled plate-shaped structure connected to the double-walled structure to be positioned outside of the hollow interior and formed contiguously from the material of the double-walled perimeter, the plate-shaped structure sized and dimensioned to completely occlude the entrance to the appendage while the double-walled perimeter is positioned inside the appendage; and
a plurality of hooks each
affixed to the outer perimeter structure
to extend away from the outer perimeter structure,
forming a barb having a J-shape, and
forming a sharp free end profile at an end of the barb.
