Patent ID: 8292907

Claim:
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 occlusive material configured to permanently occlude the body cavity disposed within the occlusion lumen, the occlusive material including extracellular matrix (ECM); 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 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.
