An apparatus and method for human female sterilization. The apparatus includes an occlusive device configured from an elongate tubular member having a central lumen and a flange formed at the proximal end. The occlusive device is formed with a plurality of flexible ribs configured to provide a plurality of seals within the interstitial portion of a Fallopian tube. A valve member is preferably disposed within the lumen of the tubular member. The occlusive device may further include a plurality of copper rings disposed between the ribs of the tubular member, or ribs may be coated with a material containing copper. The method includes placing the occlusive device within a delivery catheter having a lumen and placing the distal end of the delivery catheter within the uterus. After the occlusive device and distal end of the delivery catheter are placed in the Fallopian tube, the occlusive device is removed from the delivery catheter and ejected into the Fallopian tube. In addition, a guide wire may be inserted through the vagina and into a Fallopian tube of the uterus such that the occlusive device and the delivery catheter are threaded over the guide wire.
