“Physicians have been relying on dilation technology that is mostly unchanged from the original cervical dilator invented in 1879,” said Lucas Churchill, Vice President of Research & Development, GYN Surgical Solutions, Hologic. “We’re committed to identifying unmet needs of our customers and are proud to deliver significant advancements to one of the most commonly used devices in gynecology. In addition, the Definity dilator is a great example of our ability to leverage strategic partnerships to deliver technological innovations that advance women’s health.”

Using SureAccess balloon technology,1 the Definity dilator is designed to eliminate multiple passes and minimize false tracking, reducing injury to the cervix,2, 3 even in patients with complex or challenging cervical anatomy.

“Physicians frequently encounter variable cervical anatomy, which can create risk and increase discomfort for patients and time delay with procedures,” said Edward Evantash, M.D., Medical Director and Vice President of Global Medical Affairs, Hologic. “The Definity dilator is an innovative alternative to fixed size dilators for a range of intrauterine procedures. This gives physicians more confidence in the dilation process so they can focus on their procedures, not accessing the cavity.”

The Definity dilator is commercially available in the U.S. and comes in multiple sizes (5 mm, 7 mm and 9 mm) to accommodate a wide variety of procedures. The product was developed in partnership with CrossBay Medical, Inc., and will be featured along with other devices in the Hologic suite of surgical solutions during the American Association of Gynecologic Laparoscopists (AAGL) annual meeting from Friday, November 8 to Wednesday, November 13 at booth #913.
