ODS is an Alignment Problem
Obstructed Defecation Syndrome (ODS) occurs when the rectum becomes poorly supported, creating folds and pockets that block normal bowel movements.

Restores Alignment
ODiSi™ is a minimally invasive procedure that restores alignment to your pelvic floor without any abdominal incisions. By providing support to the rectum, ODiSi™ alleviates folds and pockets that block normal movements.

Mesh vs Native Tissue
Unlike previous treatments that use mesh, ODiSi™ uses your own natural connective tissues — a method referred to as a Native Tissue Repair.

My chronic pelvic pain—it's fully gone. This is why I call this a miracle, because many doctors have tried to help me figure this out, and now I realize it was because of my bowel.

You are Not Alone
ODS is the most common condition you've never heard of. In fact, ODS impacts:
1 in 5
of all women
3 in 5
women reporting other pelvic floor disorders
1 in 3
women with constipation
Other Pelvic Floor Disorders
Weakening of the pelvic floor can result in loss of control or comfort in the bladder, bowel, and vagina for up to 50% of women.

FAQ
Yes, absolutely.
ODS patients are always encouraged to start with non-surgical strategies, and some patients might get enough relief by combining a healthy diet, exercise and hydration with over-the-counter remedies. Bulking agents (such as Fibercon or Benefiber) and certain approved laxatives (such as Miralax), can be useful for many women with ODS.
We recommend consulting first with your primary care physician or gastroenterologist, to determine the strategies that best match your symptoms. Unfortunately, statistics show that conservative treatments result in improvement for only 30% of ODS patients, leaving many women to seek other options. ODiSi™ will change the landscape for these women, providing the first minimally invasive repair solution for ODS cases that are unresponsive to natural and behavioral management.
ODiSi™ is an intravaginal para-rectal elevation system for obstructed defecation syndrome (ODS), which represents 30% of constipation cases in women.
This condition has a major impact on quality of life, and existing surgical techniques involve invasive abdominal surgery methods with frequent use of mesh. In contrast, ODiSi™ is a mesh-free, transvaginal procedure performed in less than 30 minutes and requiring no overnight hospital stay; it will soon provide a long awaited option for millions of women with ODS.
ImPRES™ recently received the prestigious Breakthrough Technology status from the Food and Drug Administration (FDA). According to the FDA, this means the device is believed to have “significant advantages over existing approved or cleared alternatives to include reducing or eliminating the need for hospitalization, improving patient quality of life, facilitating the patients’ ability to manage their own care or establishing long-term clinical efficiencies."
ODiSi™ provides the first minimally invasive solution for the treatment of ODS in women, and the FDA Breakthrough designation will expedite and prioritize its pathway to commercialization, and its impact on the large population of women silently suffering from ODS.
Unlike some other pelvic reconstructive procedures that use mesh, ODiSi™ is a 100% mesh-free procedure.
Not necessarily. It’s very important to work with your physician, to distinguish between ODS which is an outlet / emptying problem at the level of the pelvic floor, from other types of “upper GI” constipation which may result from other causes such as hypomotility (“lazy bowel”). Patients who complain mainly of infrequent bowel movements, in the absence of ODS symptoms (such as the feeling of ‘stuck stools’, splinting and need for positional changes) are less likely to have ODS as their primary issue.
Management of upper GI constipation is important for everyone — and begins with a discussion with your healthcare provider, and usually attention to fiber intake, hydration, exercise and sometimes prescription medication.
Yes, Altyx has a suite of upcoming pelvic floor solutions, including a next-generation repair system for stress urinary incontinence (SUI) and also technologies focused on pelvic organ prolapse (POP) repair. Stay tuned for upcoming information as the Altyx launch date approaches.
Pelvic physiotherapy is an excellent consideration for many women with constipation, ODS, and other PFD’s such as urinary incontinence and pelvic organ prolapse. While it is unlikely to help with all PFD’s, it’s very often worth a try. In fact, while awaiting a PT referral or appointment, many women can reduce symptoms by performing pelvic floor exercise on their own.
