Incontinence Ring & Knob Pessary With or Without Support — 100% Silicone, 9 Sizes, Targeted Urethral Support for SUI & Prolapse

Ring support. Knob precision. One device for SUI and prolapse together. The Incontinence Ring and Knob Pessary is a highly flexible, 100% silicone pessary available with or without a supporting membrane — combining the proven support of a standard ring pessary with an elevated knob that delivers targeted urethral support for stress urinary incontinence (SUI). It is designed for patients with SUI with or without concurrent uterine prolapse, treating both conditions simultaneously with a single device. Like the standard ring, it folds for easy self-insertion and removal, making it suitable for long-term patient self-management. It also carries an important secondary clinical benefit: the ring and knob pessary can assist in predicting what type of surgical intervention may be most beneficial for the patient when conservative management is no longer the preferred path. Available in 9 sizes with or without pelvic support, and disinfectable for ongoing reuse.

Product Details

Indicated For — Conditions Treated

• Stress urinary incontinence (SUI) — primary indication; the elevated knob applies targeted upward pressure on the urethra and bladder neck to restore continence during physical activity, coughing, sneezing, or laughing
• Stress urinary incontinence with concurrent prolapse — the ring base supports prolapsed pelvic structures while the knob simultaneously manages SUI; a single device solution for both conditions
• First and second-degree uterine prolapse with SUI — ring provides mechanical prolapse support while the knob addresses incontinence
• Cystocele with SUI — With Support version provides additional anterior membrane reinforcement for bladder prolapse alongside knob-based urethral support
• Surgical planning aid — pessary trial with the incontinence ring and knob can help clinicians predict the likely outcome and most appropriate type of surgical correction when conservative therapy is being reconsidered
• With Support version — supporting membrane adds structural reinforcement for patients with concurrent cystocele or more significant prolapse alongside SUI
• Without Support version — open ring with knob for patients whose primary need is urethral support without the membrane, typically for SUI without significant cystocele

Note: Pessary fitting and ongoing management should be performed or supervised by a qualified healthcare professional. A Pessary Sizing Chart is available for clinical reference. This product is Rx only — a valid prescription or professional license is required prior to shipment.

How It Works — Ring + Knob Design & With Support vs. Without Support

The Incontinence Ring and Knob Pessary builds directly on the standard ring pessary — adding an elevated knob positioned on the ring's anterior surface to address the urethral mechanism of stress urinary incontinence. The ring component functions identically to a standard ring pessary: it sits in the vaginal canal with its edges resting against the vaginal walls, providing mechanical lift for prolapsed pelvic structures. The knob extends upward from the ring to apply gentle, targeted support to the urethra and bladder neck — the anatomical point where continence is maintained or lost. By elevating and stabilizing the urethra, the knob restores the mechanical closure pressure that weakened pelvic floor muscles can no longer sustain during increases in intra-abdominal pressure.

Because the underlying device is a ring pessary, the insertion and removal technique is identical — fold in half, lubricate the tip, insert above the pubic symphysis, and allow the ring to unfold into position. This makes it among the most patient-friendly SUI pessary options, well suited to self-management. An important secondary clinical use: a successful trial with the incontinence ring and knob pessary — where SUI resolves with the device in place — can help the clinician predict whether surgical urethral suspension procedures are likely to be effective for the patient, making it a valuable diagnostic as well as therapeutic tool.

• Elevated knob targets the urethra and bladder neck — directly addresses the mechanism of stress urinary incontinence
• Ring base provides simultaneous prolapse support — one device manages SUI and prolapse together
• Highly flexible 100% silicone — folds for easy insertion, same technique as the standard ring pessary
• Patient self-insertion and removal capable — excellent for long-term independent management
• Surgical planning aid — pessary trial helps predict likelihood of success for urethral suspension surgery
• Disinfectable — supports ongoing reuse under clinical supervision
• 9 sizes ensure accurate fitting across a wide range of anatomies
