Urinary incontinence (UI) affects twice as many women as men, primarily between the ages of 30-60, due to complications of childbirth, pregnancy and the configuration of the female urinary system. Despite the large number of women who suffer from UI, the current treatments are far from optimal, and no solution provides the control and convenience that patients need. Pharmacological therapies, pelvic muscle rehabilitation and surgery are most frequently used to treat UI. However, the non-invasive treatments (e.g., diapers) are stigmatized and uncomfortable. Surgical procedures are often ineffective, with failure rates as high at 50% for some treatments.

This E-Team, calling itself Medici Medical Technology, is developing two devices to treat stress UI in women. (The project started at an NCIIA funded program at Stanford). Stress UI is characterized by leakage that occurs during a quick (approximately one second) increase in pressure on the bladder during coughing, sneezing, hiking, sports or climbing stairs. The team’s time-delayed valve system addresses this issue by ensuring that such a short pulse of high pressure will not be sufficient to open the valves. However, when the patient does want to void, she can essentially do so normally by controlling the pressure in the abdomen for approximately three seconds, allowing each of the valves to open in series, one after another. Once all valves are open and urine is flowing, the patient will no longer need to bear down, as the pressure of the flow will keep the valves open. This device allows patients to regain their freedom and lifestyle by giving them back control of their own bodily functions while also providing convenience, requiring device changes only at each semi-annual checkup.
