The invention relates to a surgical instrument (Figs 1-3) and a method (Figs 4- 11) for treating female urinary incontinence. The instrument comprises a handle mechanism (11) and one or two curved needle-like elements (21) which are connected at opposite ends of the tape (26), which is implanted into the body. These elements can be connected one at a time with the handle and are intended to pass into the body via the vagina (28), each needle-like element being dimensioned to extend from the inside of the vaginal wall, under the pubic bone (31) and to the outside of the abdominal wall. When practicing the method, the tape is passed into the body via the vagina first at one end and then at the other end at one side and the other, respectively, of the urethra (30) to form a loop around urethra, located between urethra and the vaginal wall. The tape is extended under the pubis and through the abdominal wall and adjusted. The tape ends are cut at the abdominal wall, and the tape is left implanted in the body.

L'invention concerne un instrument chirurgical et une méthode permettant de traiter l'incontinence d'urine chez la femme. Cet instrument comporte un mécanisme de manche, ainsi qu'un ou deux éléments courbés de type aiguille reliés aux extrémités opposées de la bande, qui est mise en place dans le corps. Ces éléments, qui peuvent être reliés individuellement au manche, sont prévus pour passer dans le corps à travers le vagin. Les dimensions des éléments de type aiguille permettent à ces derniers de s'étendre depuis l'intérieur de la paroi vaginale, en passant sous l'os pubien, jusqu'à l'extérieur de la paroi abdominale. Lors de l'application de cette méthode, la bande est insérée dans le corps en passant par le vagin, par une extrémité d'abord, puis par l'autre extrémité, d'un côté et de l'autre côté de l'urètre, respectivement, afin de former une boucle autour de l'urètre, laquelle boucle est située entre l'urètre et la paroi vaginale. La bande est étendue sous le pubis et à travers la paroi abdominale, puis ajustée. Les extrémités de la bande sont coupées au niveau de la paroi abdominale, et la bande reste en place à l'intérieur du corps.
