Abstract

A vascular occlusion device for occluding a body cavity. The device includes an elongate member having an inflation lumen, an occlusion lumen, and a first portion extending distally from a proximal end and a second portion extending distally from the first portion to the distal end. An inflatable proximal balloon is disposed about the first portion and an inflatable distal balloon is disposed about the second portion. The inflation lumen is configured to inflate at least one of the balloons. The occlusion lumen is configured to introduce an occlusive material into the body cavity by way of an occlusion port located between the two balloons to occlude the body cavity. In some examples, the body cavity includes a patent foramen ovale.

Claims

1. A vascular occlusion device for occluding a body cavity defined by cavity walls, the device comprising:

an elongate member extending from a proximal end to a distal end and including a first portion extending distally from the proximal end and a second portion extending distally from the first portion to the distal end, a first inflation lumen and an occlusion lumen being formed longitudinally in the first portion, and a second inflation lumen being formed longitudinally in the second portion;

an inflatable proximal balloon including a proximal balloon wall being disposed about the first portion and defining a proximal balloon interior;

an inflatable distal balloon including a distal balloon wall being disposed about the second portion and defining a distal balloon interior;

the first and second portions respectively having first and second inflation orifices, the first inflation lumen being configured to introduce an inflation fluid into at least one of the balloon interiors by way of the respective inflation orifices; and

the elongate member having an occlusion port defined between the proximal and distal balloons, the occlusion lumen being configured to introduce an occlusive material into the body cavity by way of the occlusion port to occlude the body cavity.

2. The device of claim 1 wherein the second inflation lumen is in fluid communication with the first inflation lumen, the first inflation lumen being configured to introduce the inflation fluid into each of the balloon interiors by way of the respective inflation orifices and the second inflation lumen.

3. The device of claim 1 wherein the elongate member further comprises an inner wall defining an inner lumen extending therethrough.

4. The device of claim 3 wherein the elongate member further comprises an elongate inner element extending from the proximal end to the distal end and including the second portion, the distal balloon, and the second inflation lumen;

the inner element being disposed within the inner lumen for relative axial movement such that the distal balloon may translate axially relative to the proximal balloon;

the second inflation lumen being configured to introduce the inflation fluid into the distal balloon interior by way of the second inflation orifice.

5. The device of claim 4 wherein the second inflation lumen is configured to introduce the inflation fluid into the distal balloon interior independently of the first inflation lumen introducing the inflation fluid into the proximal balloon interior.

6. The device of claim 4 wherein the occlusion lumen and the occlusion port are defined in the first portion of the elongate member.

7. The device of claim 4 wherein the inner element further includes an element wall defining an element lumen extending therethrough.

8. The device of claim 4 wherein a distal segment of the first portion includes an atraumatic taper.

9. The device of claim 1 wherein the occlusive material includes at least one of a polyvinyl alcohol, cyanoacrylate, and small intestine submucosa.

10. The device of claim 1 wherein a removable film is attached to a distal part of the proximal balloon and a proximal part of the distal balloon.

11. The device of claim 1 wherein an occlusion device is disposed about the occlusion port to provide a support structure for the occlusive material.

12. The device of claim 10 wherein the occlusion device includes an embolization coil.

13. The device of claim 1 wherein the balloons are removably attached to the elongate member.

14. A vascular occlusion assembly for occluding a body cavity defined by cavity walls, the assembly comprising:

an outer sheath having a proximal section extending to a distal section and defining a sheath lumen therein, an elongate vascular occlusion device being disposed within the sheath lumen and the outer sheath being configured to translate axially relative to the elongate occlusion device;

the occlusion device comprising an elongate member extending from a proximal end to a distal end and including a first portion extending distally from the proximal end, a second portion extending distally from the first portion to the distal end, a first inflation lumen and an occlusion lumen being formed longitudinally in the first portion, a second inflation lumen being formed longitudinally in the second portion, and an inner wall defining an inner lumen extending longitudinally through the elongate member;

an inflatable proximal balloon including a proximal balloon wall being disposed about the first portion and defining a proximal balloon interior;

an inflatable distal balloon including a distal balloon wall being disposed about the second portion and defining a distal balloon interior;

the first and second portions respectively having first and second inflation orifices, the first inflation lumen being configured to introduce an inflation fluid into at least one of the balloon interiors by way of the respective inflation orifices; and

the elongate member having an occlusion port defined between the proximal and distal balloons, the occlusion lumen being configured to introduce an occlusive material into the body cavity by way of the occlusion port; and

a longitudinally extending wire guide being disposed within the inner lumen and configured such that the elongate occlusion device may translate axially along the wire guide.

15. The device of claim 14 wherein the second inflation lumen is in fluid communication with the first inflation lumen, the first inflation lumen being configured to introduce the inflation fluid into each of the balloon interiors by way of the respective inflation orifices and the second inflation lumen.

16. The device of claim 14 wherein the elongate member further comprises an elongate inner element extending from the proximal end to the distal end and including an element wall defining an element lumen extending longitudinally therethrough;

the inner element including the second portion, the distal balloon, and the second inflation lumen, the inner element being disposed within the inner lumen for relative axial movement therein such that the distal balloon may translate axially relative to the proximal balloon, and the wire guide being disposed within the element lumen;

the second inflation lumen being configured to introduce the inflation fluid into the distal balloon interior by way of the second inflation orifice.

17. The assembly of claim 16 wherein the occlusion port is defined in the first portion, and a distal segment of the first portion includes an atraumatic taper.

18. The device of claim 14 wherein the occlusive material includes at least one of a polyvinyl alcohol, cyanoacrylate, and small intestine submucosa.

19. A method of occluding a body cavity having body walls, the method comprising:
