The linear everting catheter: a nonhysteroscopic, transvaginal technique for access and microendoscopy of the fallopian tube.

The linear everting catheter is a new technology that allows for nonhysteroscopic, transvaginal access, and microendoscopy of the fallopian tube. Initial results indicate that this approach is safe, successful, and offers a number of unique advantages relative to the available alternatives. Studies are in progress to explore several of the many possible applications of this system in the diagnosis and treatment of infertile patients.
