The results are presented for 12 patients with the AS721 sphincter, 10 with the AS761 and 8 with the AS742. While followup of patients receiving the AS742 device is short it is anticipated that the improved design of this model will result in a low incidence of mechanical problems.
结果呈现了12例使用AS721括约肌的患者、10例使用AS761的患者以及8例使用AS742的患者的情况。虽然接受AS742装置的患者随访时间较短，但预计该型号的改进设计将导致机械问题的发生率较低。
