Amelioration of urinary incontinence in females

A surgical method and complementary apparatus for limiting the amount of food digestion. Accordingly, parts of the small intestine are used for forming alternative routes to the ingested food to decrease the interaction withdigestive tissue. One or more constrictors are used to divert or stop the digested food flow in a certain length of the small intestine. The constricting mechanism for diverting ingested food into alternative routes of the digestive system, uses two blocks that can be pressed together over the small intestine, while a mechanical barrier is inserted over the main blood vessel at the site of constriction, to limit pressure over said vessels
