Description

TECHNICAL FIELD

The present disclosure relates in general to a flexible and non-absorbent vaginal insert device for use in improving symptoms associated with pelvic organ prolapse and urinary incontinence when the device is inserted, and more particularly to a vaginal insert device that is easier to insert and remove.

BACKGROUND

Stress Urinary Incontinence (SUI) and Pelvic Organ Prolapse (POP) are growing problems globally that not only cost health care systems large amounts of money, but severely degrade the quality of life of tens of millions of women in the United States alone. Although surgical solutions can succeed in ameliorating symptoms associated with SUI and POP, surgery is not without risks and complications and may even leave the patient in a worse situation than before treatment. See Huang W, Wang T, Zong H, Zhang Y, Efficacy and Safety of Tension-Free Vaginal Tape-Secure Mini-Sling Versus Standard Midurethral Slings for Female Stress Urinary Incontinence: A Systematic Review and Meta-Analysis, International Neurourology Journal, 2015, 19(4):246-58, which is incorporated herein by reference. See also Ellington D R, Erekson E A, Richter H E, Outcomes of Surgery for Stress Urinary Incontinence in the Older Woman, Clin Geriatr Med., 2015, 31(4):487-505, which is incorporated herein by reference. The FDA has issued several Public Health Notifications regarding surgical mesh placed through the vagina (transvaginal placement) to treat POP and SUI. The FDA identified serious and frequent complications with surgical mesh, including mesh erosion through the vagina, pain, infection, bleeding, discomfort during intercourse, organ perforation, urinary problems, recurrent prolapse, neuro-muscular problems, vaginal scarring/shrinkage & emotional problems. Most surgical complications require intervention including medical, additional surgical treatment and hospitalization.

Prior art pessaries, which have been most commonly used for management of female POP but also have been used for SUI, have presented a viable non-surgical option for treating SUI and POP. These prior art pessaries have had few complications and side effects. However, these devices are traditionally placed in the vagina for an extended period of time. They may also be uncomfortable. Furthermore, these prior art devices have been difficult for the patient to insert and remove, and use, insertion and removal of these devices have often required regular office visits with a physician for years. See, Jones K A, Harmanli O, Pessary Use in Pelvic Organ Prolapse and Urinary Incontinence, Rev Obstet Gynecol, 2010, 3(1):3-9, which is incorporated herein by reference. Difficulty with self-removal and insertion of the pessary, having the pessary fall out during defecation, and lack of comfort and convenience may be limiting widespread use of the prior art devices.

Stress Urinary Incontinence (SUI) in women, is the involuntary leakage of urine due to a weakened pelvic support system and/or pressure on the bladder from aging, genetics, or childbirth. The Urology Care Foundation estimates that one of every three women will experience SUI at some point in their lifetime. There are a few types of urinary incontinence including stress incontinence, urge incontinence and mixed incontinence. All are mainly due to connective tissue laxity or damage in the vagina or supportive ligaments. See An Integral Theory and Its Method for the Diagnosis and Management of Female Urinary Incontinence, Petros P E, Ulmsten U I, Scand J Urol Nephrol Suppl, 1993, 153, 1-93, which is incorporated by reference. FIG. 1 is a cross-section of the pelvic region of a female with normal anatomy illustrating the uterus 10, cervix 12, bladder 14, urethra 16, vagina 18, and rectum 20. FIG. 2 illustrates urinary incontinence (i.e., leakage of urine) 22 caused by stress or pressure 24 on the bladder 14. Involuntary leakage of urine often occurs during activities such as coughing, laughing, sneezing, lifting or exercise.

Connective tissue damage to three zones of the Integral System, which encompasses all three pelvic organs, including the bladder, vagina and ano-rectum, is the ultimate cause of Pelvic Organ Prolapse (POP) and dysfunction in these organs. FIG. 3 is a cross-section of the pelvic region of a female with a prolapsed bladder 26. FIG. 4 is a cross-section of the pelvic region of a female with a prolapsed back-passage 28. FIG. 5 is a cross-section of the pelvic region of a female with a prolapsed uterus 30. POP is commonly due to child bearing but may also be caused simply by genetics and the aging process.

Therefore, there is a need for a pessary or other vaginal insert device that manages, improves, or eliminates female incontinence, POP or both incontinence and POP. There is a further need for such a pessary or other vaginal insert device that does not require a prescription, and is non-absorbent, over the counter, convenient, comfortable, and easy for a patient to insert and remove, with no or minimal physician intervention. Preferably such a vaginal insert device would also be reusable, but it also can be disposable.
