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 the occlusive material into the body cavity by way of the occlusion port to occlude the body cavity;
wherein a first removable film is attached to a distal part of the proximal balloon and a second removable film is attached to a proximal part of the distal balloon, the removable films being configured to inflate with the balloons, attach to the occlusive material following introduction of the occlusive material into the body cavity, and detach from the balloons upon deflation of the balloons.

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.
