Abstract

A device for occluding a perforation in a blood vessel includes a catheter shaft that has a first lumen and a second lumen. The first lumen is adapted to receive at least one of a guidewire and an implanted cardiac lead, and the second lumen is adapted to receive an inflation fluid. The device further includes an inflatable balloon that is carried by the catheter shaft. The inflatable balloon is adapted to receive the inflation fluid from the second lumen. The inflatable balloon has a working length of about 65 mm to about 80 mm and an inflated diameter of about 20 mm to about 25 mm.

Claims

1. A device for occluding a perforation in a blood vessel, the device comprising:

a catheter shaft having a first lumen and a second lumen, the first lumen being adapted to receive at least one of a guidewire and an implanted cardiac lead, and the second lumen being adapted to receive an inflation fluid, wherein the second lumen includes a cross-sectional area at a location along a length of the catheter shaft between 0.65 mm² and 1.90 mm²; and

an inflatable balloon carried by the catheter shaft and adapted to receive the inflation fluid from the second lumen, the inflatable balloon having a working length of about 65 mm to about 80 mm, and the inflatable balloon having an inflated diameter of about 20 mm to about 25 mm.

2. The device according to claim 1, wherein the inflatable balloon comprises polyurethane.

3. The device according to claim 1, wherein the inflatable balloon comprises a proximal tapered portion, a distal tapered portion, and a working portion disposed between the proximal tapered portion and the distal tapered portion, the working portion having the inflated diameter of about 20 mm to about 25 mm.

4. The device according to claim 1, wherein the first lumen and the second lumen are non-concentrically disposed within the catheter shaft.

5. The device according to claim 4, wherein the cross-sectional area of the second lumen includes a crescent shape.

6. The device according to claim 5, wherein the cross-section area of the second lumen is about 1 mm².

7. The device according to claim 5, wherein the crescent-like cross-sectional shape has a radius of about between 0.50 mm to 1.50 mm.

8. The device according to claim 7, wherein the radius of the crescent-like cross-sectional shape is about 1 mm.

9. The device according to claim 1, further comprising at least one radiopaque marker at least a first radiopaque marker carried by the catheter shaft and a second radiopaque marker carried by the catheter shaft.

10. The device according to claim 9, wherein the at least one radiopaque marker further comprises at least a third radiopaque marker.

11. The device according to claim 10, wherein the inflatable balloon comprises a proximal portion, a distal portion, and an intermediate portion disposed between the proximal and distal portions, wherein the first, second, and third radiopaque markers are carried within the inflatable balloon, and wherein the first radiopaque marker is axially aligned with the proximal portion, the second radiopaque marker is axially aligned with the intermediate portion, and the third radiopaque marker is axially aligned with the distal portion.

15. The device according to claim 1, further comprising an occlusion patch detachably carried by the inflatable balloon, the occlusion patch being deployable from the inflatable balloon to occlude the perforation.

16. The device according to claim 15, wherein the occlusion patch includes at least one adhesive adapted to maintain a position of the occlusion patch within the blood vessel.

17. The device according to claim 16, wherein the at least one adhesive is adapted to be activated by application of at least one of heat, pH, and light.

18. The device according to claim 15, wherein the occlusion patch includes a scaffold structure adapted to facilitate tissue growth therein.

19. The device according to claim 15, wherein the occlusion patch includes stem cells to facilitate bioabsorption of the occlusion patch.

20. The device according to claim 15, wherein the occlusion patch includes at least one hormonal agent adapted to promote wound healing.
