Abstract
Abstract A gynaecological surgical device to avoid Fallopian tubes becoming blocked again during cicatrisation following a tuboplasty operation, such device comprising a hollow cone of flexible sheet material and a cord firmly fixed to the apex of the cone. In use after performing a salpingostomy of the blocked portion of a patient''s Fallopian tube, the device is placed with the apex extending into the cut end of the tube with the cord extending to the abdominal wall. The base edge of the cone is folded around the end of the tube and secured to the tube exterior to prevent blockage during cicatrisation of the tube. When this is completed, the device can be removed simply by pulling the cord.
