Claim:
1. A sterilizing device implantable into a patient's reproductive lumen, comprising: an expandable occluding component that is self-expandable upon deployment from a catheter within a patient's reproductive lumen; a first barrier component comprising a first membrane that is configured to expand across the reproductive lumen upon self-expansion of the expandable occluding component within the patient's reproductive lumen such that the first membrane is immediately impermeable to the passage of human sperm cells upon deployment of the expandable occluding component; a second barrier component comprising a second membrane that is configured to expand across the reproductive lumen upon self-expansion of the expandable occluding component within the patient's reproductive lumen such that the second membrane is immediately impermeable to the passage of human sperm cells upon deployment of the expandable occluding component; and at least one fibrous mass that is disposed within one end of the expandable occluding component such that the fibrous mass is permeable and facilitates tissue growth into the expandable occluding component, wherein the fibrous mass is positioned parallel to the first membrane and configured to expand with a wall of the expandable occluding component, and wherein the fibrous mass is made of a foam material; wherein the expandable occluding component has an elongated tubular shape with first and second ends and an inner lumen extending between the first and second ends, the first membrane is disposed over the first end, and the second membrane is disposed over the second end.
