Abstract
A collapsible medical device and associated methods for occluding an abnormal opening in, for example, a body organ, wherein the medical device is shaped from a heat treatable metal fabric. The metal fabric is formed from a plurality of metal strands and is heat treated within a mold in order to substantially set a desired shape of the device. The medical device includes a fastener for attaching to the end of a guide wire or delivery catheter, wherein the shape of the medical device is formed such that the fastener is attached to the metal fabric within a recess formed in the shape of the medical device. A medical device having a preselected shape is delivered through a catheter or the like for deployment in a desired channel or opening in a patient's body. The medical device may be shaped, for example, to occlude an ASD, PDA, or a VSD.
