DEVICE CLASSIFICATION PelvX Incontinence Dish Vaginal Pessary is classified by the FDA under the heading of Vaginal Pessary (21 CFR Section 884.3575) as a Class II device with Product Code: 85HHW. #### STATEMENT OF SUBSTANTIAL EQUIVALENCE 4. PelvX Incontinence Dish Vaginal Pessary is substantially equivalent to the Milex Incontinence Dish pessary, manufactured by Milex Products, Inc., Chicago, IL 60631. A comparison of the PelvX Devices versus the Milex Devices is presented in Tables 1 and 2. ### 5. INTENDED USE The PelvX Incontinence Dish Vaginal Pessary is intended for treatment of stress urinary incontinence combined with a mild 1st or 2nd degree uterine prolapse and/or a mild cystocele. #### DESCRIPTION OF DEVICE 6. The PelvX Incontinence Dish Vaginal Pessary is a pessary intended for the treatment of stress urinary incontinence. It is made of medical grade silicone and is shaped like a dish to surround and support the cervical area and bladder areas. Holes in the dish allow drainage of vaginal fluids. It features a bulbous portion at one location on its circumference designed to support and elevate the bladder neck, thereby providing improved urethral sphincter control. Figure 1 shows a diagram of the PelvX Incontinence Dish. {1}------------------------------------------------ ### 7. SUBSTANTIAL EQUIVALENCE COMPARISON Tables 1 and 2 demonstrate the regulatory classifications and features of the DesChutes Incontinence Ring compared to the Milex Incontinence Ring. The common and classification names for these products are identical. In addition, both of these devices are prescription devices. These vaginal pessaries are reusable devices which must be fitted, checked for continuing fit, and monitored for developing problems by medical personnel. The DesChutes and Milex Dishes have identical intended uses. The contraindications for their use are also the same. The pessaries are supplied clean but not sterile. Cleaning procedures are also the same. Both devices come in a variety of sizes for fitting. There are several differences between the DesChutes and Milex products. First, DesChutes explicitly states that these are single patient devices while Milex is silent on this point. Second, DesChutes adds a precaution that the pessary should be removed before coitus. Finally the pessaries are packaged differently which does not affect the intended use or performance of the product. | Category | DesChutes Medical Products<br>PelvX Incontinence Dish | Milex Products<br>Incontinence Dish with<br>Support | |-----------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------| | Common or usual name | vaginal pessary | vaginal pessary | | Classification name | 884.3575 Vaginal pessary | 884.3575 Vaginal pessary | | Product Code | 85HHW | 85HHW | | Prescription device | Yes | Yes | | Feature | DesChutes Medical Products<br>PelvX Incontinence Dish | Milex Products<br>Incontinence Dish<br>with Support | | Intended Use | treatment of stress urinary incontinence combined with 1st or 2nd degree prolapse and/or a mild cystocele | stress urinary incontinence coupled with a mild 1st or 2nd degree prolapse and/or a mild cystocele | | Single patient device | yes | implied but not specifically stated | | Single use or reusable | reusable | reusable | | Must be initially fitted by<br>medical personnel | yes | yes | | Requires regular visits to<br>medical personnel for<br>checking | yes | yes | | Contraindications | 1) pelvic infections or<br>lacerations<br>2) non-compliant patients<br>3) endometriosis<br>4) pregnancy | 1) pelvic infections or<br>lacerations<br>2) non-compliant patients<br>3) endometriosis<br>4) pregnancy | | Cautions | 1) pessary should be removed before coitus | | | Sterilization status | clean, but not sterile | clean, but not sterile | | Foldable | yes | yes | | Maintenance | clean with warm water and soap when removed | clean with water and mild soap when removed | | Material<br>Outer | medical grade silicone | medical grade silicone | | Color additives | yes | yes | | Number of models | 6 | 6 | | Sizes | 2.25", 2.5", 2.75", 3", 3.25",<br>3.5" | 55mm, 60mm, 65mm, 70mm,<br>75mm, 80mm, 85mm | | Instructions | physician and patient<br>instructions | physician/nurse and patient<br>instructions | | Packaging | plastic bag inside paperboard box with label | plastic clamshell with instructions for use visible | ### Table 1-Comparison of Regulatory Classifications {2}------------------------------------------------ ## Table 2 -Comparison of Device Features #### 8. SUMMARY OF SAFETY TESTING The DesChutes PelvX Incontinence Dish is made of a known medical grade silicone. Extensive testing of this silicone was performed for DesChutes Medical Products by NamSA. The following tests were performed: {3}------------------------------------------------ Acute Systemic Toxicity Cytotoxicity Muscle Implantation (1 week) Muscle Implantation (4 weeks) Muscle Implantation (12 weeks) ISO Sensitization Study Pyrogenicity Vaginal Irritation (14 days) The material used is the same as for the DesChutes Donut Pessary (510(k) #974117). This testing regime was compared to requirements in "General Purpose Memorandum G95-1 Use of International Standard ISO-10993" for devices in contact with mucosal membranes for between 24 hours and 30 days. The test results support the position that this material is substantially equivalent to the other materials used for similar purposes. {4}------------------------------------------------ Image /page/4/Figure/0 description: This image shows a technical drawing of a pessary incontinence dish.
