Materna Medical

FDA-cleared devices for the parts of women's health medicine kept skipping - from painful sex to the delivery room.

The plate reads "Materna Medical." Behind it: two devices, sixteen years, one CEO who keeps raising money in a market that funds almost no one who looks like her. She is not making a statement. She is filling a gap.

The Story

A device company for the things nobody prints on a billboard

There is a version of the women's health market that gets the attention: fertility apps, period trackers, glossy consumer brands with lowercase logos. And then there is the other part - vaginismus, painful intercourse, the pelvic floor muscles that tear during childbirth. It is a large market. It is also a market that, for reasons that are more cultural than clinical, medicine mostly declined to build devices for. Materna Medical, a company in Mountain View, California, decided to build them anyway.

The pitch is unusually clean for a health company. Materna sizes the opportunity in women's pelvic health at roughly $6 billion, and it is not obviously wrong, because the need was never small - it was ignored. The company's answer is a portfolio of two devices sitting at opposite ends of a woman's life. One is already FDA-cleared and sold to consumers. The other is in clinical trials and aimed at the delivery room. Both are the kind of unglamorous, physical, regulated products that take a long time and don't trend on social media.

That is worth sitting with, because the interesting thing about Materna is not that it found a big market. Lots of companies find big markets. The interesting thing is that it chose the version of the market that requires FDA clearances, pivotal trials, and the patience to spend sixteen years building two products. In an industry that prizes speed, Materna is a slow company on purpose. When the product goes inside a patient during labor, slow is the responsible answer.

"Empowering women to protect and restore their pelvic health at every stage of life."

What They Make

Two devices, one idea taken seriously

FDA-Cleared · On Market

Milli

The first and only vaginal dilator that expands incrementally, one millimeter at a time, with optional vibration. It's cleared to treat vaginismus and dyspareunia - painful intercourse - and since 2023 it's available over-the-counter, no prescription required. Where the old approach handed patients a bag of rigid plastic cones and a shrug, Milli lets the user set the exact size. The name is the mechanism: one milli-meter at a time.

Ellora Obstetrical System

Formerly known as Materna Prep, Ellora is an expanding obstetrical dilator placed in the vagina during the first stage of labor. It gradually pre-stretches the pelvic floor muscles over a longer, gentler window than the baby's passage allows - the goal being to make vaginal delivery easier, faster and safer. In a pilot study, the device reduced pelvic floor injury by 60%. It is now being evaluated in the EASE pivotal trial in first-time mothers.
