1. A collapsible medical device comprising:
a tubular metal fabric including a plurality of braided metal strands and defining a proximal end and a distal end, the tubular metal fabric having a collapsed configuration for delivery through a channel in a patient's body and an expanded configuration for substantially creating an occlusion of an opening in the patient's body,
wherein, in the expanded configuration, the tubular metal fabric defines a first portion having a first diameter proximate the proximal end, a second portion having a second diameter proximate the distal end, and a third portion having a third diameter extending between the first portion and the second portion, wherein the third diameter is less than the second diameter and the second diameter is less than the first diameter,
wherein the first portion has a preset disk shape,
wherein the second portion has a preset shape that is configured to be deployed within the opening to be occluded and to maintain a tension between the first portion and the second portion when the medical device is positioned within the patient's body, the preset shape of the second portion including (i) a proximal end portion defining a recess in which the third portion is at least partially received, (ii) a cylindrical portion extending distally from the proximal end portion, and (iii) a tapering portion extending distally from the cylindrical portion,
wherein the second portion includes a plurality of hooks configured to engage tissue proximate the opening in the patient's body when the medical device is in place,
wherein each of the plurality of hooks is formed of a wire having a hook shape at each end of the wire and a bend of about 180 degrees in a mid-length segment of the wire to create two interconnected hooks.
