    摘要: Methods and devices for occlusion of the fallopian tubes of a women. The method involves thermally damaging the lining of the utero-tubal junction with relatively low power, followed by placement of a reticulated foam plug. In one embodiment, vascularized tissue grows into the plug and prevents or discourages formation of scar tissue around the plug. Another embodiment with a relatively small foam pore size encourages formation of a vascularized capsule around the plug. The presence of this vascularized capsule limits the patient's foreign body response, so that the capsule does not constrict around the plug. Also presented is a catheter designed for wounding the epithelial layer of the utero-tubal junction, and a method of using the catheter to form a long yet shallow lesion in the utero-tubal junction.

    摘要: 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.
