The first episode of the Surgeon's Cut [0] on Netflix shows a doctor:

- operating in utero

- while the mother is awake

- in an outpatient/doctor's office setting

- to implant a balloon in the upper respiratory tract of a fetus with a, I believe, cleft palate so that it's lungs can develop normally.

It really is wild what modern medicine can do these days.
