Abstract
A contraceptive device is provided including an occluding component for deployment in a tubal lumen of a reproductive organ. The device includes an expandable frame reversibly expandable from a collapsed state to an expanded state and a barrier supported by the expandable frame. In the expanded state the barrier is disposed between the expandable frame and walls of the lumen to inhibit in-growth of cellular material into and onto the occluding component, and additionally the barrier is urged against walls of the tubal lumen to define at least two tube lumen sealing areas, disposed perpendicular to a longitudinal axis of the walls of the tube lumen such that (i) the expandable frame is disposed between the two tubal lumen sealing surface, and (ii) passage of reproductive cells through the expandable frame, and through the tube lumen is blocked, therefore, creating a the complete blockage for liquids from a first part of the tube to a second part of the tube, downstream the first part. Other applications are also described.
