Claims
- 1. A collapsible medical device, comprising a plurality of metal strands woven into a tubular woven metal fabric having a proximal end and a distal end, each end having a means for securing each end attached to said tubular woven metal fabric, thereby gathering said strands and inhibiting unraveling of the strands, said tubular woven metal fabric having an expanded preset configuration shaped to create an occlusion of an abnormal opening in a body organ, said expanded preset configuration being in a shape of a bell 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.
- 2. The medical device as recited in claim 1, wherein said means for securing each end has a threaded bore for rotational attachment to a delivery device.
- 3. The medical device as recited in claim 2, further including an occluding fiber retained within a hollow central portion formed by said tubular woven fabric.
- 4. The medical device as recited in claim 1, wherein the metal fabric is manufactured from an alloy selected from the group consisting of stainless steel, nickel-titanium, and cobalt-chromium-nickel.
- 5. The medical device as recited in claim 4, further including an occluding fiber retained within a hollow central portion formed by said tubular woven fabric.
- 6. The medical device as recited in claim 1, further including an occluding fiber retained within a hollow central portion formed by said tubular woven fabric.
- 7. A collapsible medical device, comprising: a tubular woven metal fabric including a plurality of braided strands and having a proximal end and a distal end, each end having a clamp attached to said metal fabric to thereby gather said strands together and inhibit unraveling of the strands, said metal fabric having a collapsed configuration for delivery through a channel in a patient's body and a generally dumbbell shaped expanded preset configuration for substantially creating an occlusion of an abnormal opening in a body organ, the metal fabric in its expanded configuration having two expanded diameter portions and a reduced diameter portion disposed between the two expanded diameter portions, each expanded diameter portion having an inner and outer wall, wherein the inner wall of at least one of the expanded diameter portions is generally concave.
- 8. The medical device as recited in claim 7, further including an occluding fiber retained within a hollow central portion formed by said generally dumbbell shaped expanded configuration.
- 9. A collapsible medical device, comprising a tubular woven metal fabric including a plurality of braided strands and having a proximal end and a distal end, each end having a clamp attached to said tubular woven metal fabric to thereby gather said strands together and inhibit the strands from unraveling, said tubular woven metal fabric having an expanded preset configuration shaped to create an occlusion of an abnormal opening in a body organ, said expanded preset configuration being deformable to a lesser cross-sectional dimension for delivery through a channel in a patient's body, wherein the expanded preset configuration comprises two expanded diameter portions and a reduced diameter portion, said reduced diameter portion having a length approximating a thickness of a patient's atrial septum, the woven metal fabric having a memory property whereby the medical device tends to return to said expanded preset configuration when unconstrained.
- 10. The medical device as recited in claim 9, wherein said clamp has a threaded bore adapted for rotationally receiving a delivery device.
- 11. The medical device as recited in claim 9, further including an occluding fiber contained within a hollow center portion formed by said tubular woven metal fabric.
- 12. The medical device as recited in claim 9, wherein the metal fabric is manufactured from an alloy selected from the group consisting of stainless steel, nickel-titanium, and cobalt-chromium-nickel.
