membrane sealant

Full Definition

Biocompatible material applied to seal fetal membrane defects and prevent amniotic fluid leakage after fetal surgery procedures. These sealants are designed to provide temporary but durable closure of membrane openings while allowing normal membrane healing. Various types include fibrin-based sealants, collagen patches, and synthetic materials. Effective membrane sealing is crucial for maintaining normal amniotic fluid volume and preventing preterm labor following fetal intervention.
