A Single Device for Vaginal Dilation and Flushing

Technology No. 2019-196
IP Status: PCT Patent Application Filed; Application #: PCT/US20/022704

Vaginal Dilation and Flushing Device for Long-term Use

This medical device is a modular vaginal dilation and flushing device that helps improve patient compliance and prevent serious postoperative complications associated with vaginoplasty. Patient compliance is improved by reducing the number of painful dilation and douching procedures required during the 90-days post-op period. The device can be used for preventing both acute and chronic post-op complications, including risks of infection, necrosis due to uneven pressure, vaginal stenosis, and neovaginal prolapse.

Modular Design to Minimize Dilator Removal Frequency

By exploiting a stent design, the device reduces severe complications caused by vaginal packing with lubricated gauze, and frequent insertion and removal of hard plastic dilators. This all-in-one modular device replaces lubricated gauze, plastic dilators, and the douching mechanisms that are commonly used in perioperative and postoperative period following a vaginoplasty procedure. The device is designed to simultaneously provide uniform radial support to the neovaginal cavity as well as facilitate douching procedures. The flexible stent layer and soft external layer reduces pain during dilation/cleaning procedures, thereby improving patient compliance and reducing the risk of tissue trauma, infection, skin slough or vaginal prolapse. Channels built in the device promote coating of douching fluid to the entire neovagina, providing a better clean than typical douching.
