The complex cardiovascular relationship between a mother and her fetus is at the heart of fetal and pregnancy studies. Understanding how the mother’s physiology and pathology impacts the growing fetus requires extensive and careful instrumentation. The impact of pharmaceutical agents upon the fetus benefits from measuring both pressure and flow to identify changes in vascular resistance.

Successful chronic implantation of both the mother and the fetus has been performed using Transonic’s Implantable flow probes and EndoGear® telemetry system. EndoGear® is particularly suited for studying fetal parameters as it is completely internalized, removing the need for cables to exit the uterus, allowing the pregnancy to come to term with the birth of the instrumented infant.
