Abstract:
An artificial occlusion kit for implanting and retaining an artificial occlusion device in a body space to be occluded adjacent to and extending from a body lumen in a mammal, comprising:at least one occlusion device adapted for filling at least a portion of the body space; anda retaining device assembly having a retaining device adapted to be delivered at a retaining site in the body lumen adjacent to the body space, said retaining device being removed from the body lumen after said at least one occlusion device is deployed, said retaining device having two opposite ends and forming a first shape with a first outer diameter, said retaining device being expandable to a second shape having a second outer diameter larger than said first outer diameter and sufficient to engage a body lumen wall at the retaining site such that a barrier is formed against migration of said at least one occlusion device out of the body space and into the body lumen, said second shape also defining at least one semi-penetrable space between the body space to be occluded and the adjacent body lumen wherein said at least one occlusion device forms a first occlusion device shape that is advanceable through said semi-penetrable space, and said at least one occlusion device is also expandable to a second occlusion device shape that is not advanceable through said semi-penetrable space, said second shape also forming a lumen along a longitudinal axis sufficient to allow flow of fluids therethrough.
