Between 1982-87, shape memory @entity702 alloy clips were employed for female sterilization by minilaparotomy in 1002 cases. This clip was noncorrosive and had high histocompatibility. The clip was designed to open in ice water between 0 degrees-4 degrees Celsius and close a t between 30 degrees-40 degrees Celsius spontaneously. It was placed vertically over the isthmus 3 cm away from the uterine cornus to avoid blood vessels in the mesosalpinx. Clip application was @entity532 . On followup, only 6.3% had mild @entity1866 . The failure rate was 0.89%. Midluteal @entity1420 (P) and @entity53 (E2) were determined in 91 clip @entity1 ; 21 normal worn and 27 tubal ligation cases served as controls. The serum P levels were similar in cases and normal controls. There were significant differences in serum P between clip and tubal ligation groups, scanning electron microscopy examination of @entity95 tube with clip showed limited destruction of the tubal mucosa with normal cilia and cells at the border. The clip produced little disturbances in the ovarian blood supply and the least destruction of the tubal mucosa. (author's modified)
