Abstract:
A collapsible medical device, comprising a plurality of metal strands woven into a woven metal fabric having a proximal end and a distal end, each end having a means for securing each end attached to said woven metal fabric, thereby gathering said strands and inhibiting unraveling of the strands, said woven metal fabric having an expanded preset configuration shaped to create a restriction in a blood vessel, said expanded preset configuration being in a shape of a cylindrical disk of a predetermined thickness having at least one enlarged lumen extending through the thickness dimension of said disk through which blood may flow and deformable to a lesser cross-sectional dimension for delivery through a channel in a patient's body, the woven metal fabric having a memory property whereby the medical device tends to return to said expanded preset configuration when unconstrained.
