Study Arms (1)

Fetoscopes for Selective Laser Photocoagulation

EXPERIMENTAL

Single arm study. All patients will undergo selective laser photocoagulation with the use of the fetoscopes in this study.

Device: Fetoscopy Sets for Anterior and Posterior Placentas

Interventions

Patients who choose to undergo fetoscopic surgery for a complicated monochorionic-diamniotic pregnancy will be offered participation in this study. All patients will undergo selective laser photocoagulation with the use of the fetoscopes in this study.
