The bladder and urethra play a key role in pelvic organ prolapse and stress urinary incontinence. The most frequent cause of SUI is early bladder prolapse.
As we age, the bladder loses support from neighboring fascia, muscles, ligaments and tendons and drops down, folding itself over supporting structures underneath (and over slings or sutures after surgeries). The folding narrows the outlet or urethra. Imagine you are holding a rolled up throw rug under one arm to carry it, it folds over and the hole inside it narrows and flattens.
Mesh illustrations in journal articles, public information handouts, and patent applications are inaccurately show the urethra as a straw-shaped tube through which urine flows. See example in Figure 1. It is really a sideways funnel — “offset” like the photo of the oil funnel in Figure 2. Figure 3. is a healthy bladder.
How in the world did the patent office and the FDA clear this product, a mesh tape with wing-like extensions for treating female urinary incontinence US 8047982 B2, when the illustration clearly shows a tube and the device is designed to fit a straight tube?
