Abstract: Disclosed herein is a device adapted for occluding the ovarian pathway of a female body for sterilization purposes. The device delivers RF energy to wound tissue at a desired location within at least one fallopian tube and implants a porous foam plug adjacent to the wounded tissue at said location. Depending on the plug's pore sizes, vascularized tissue may grow into the plug to prevent or discourage the formation of scar tissue around the plug and/or a vascularized capsule may form around the plug, which limits the patient's foreign body response so that the capsule does not constrict around the plug.
