Magnetically Controlled Microrobot for Embryo Transfer in Assisted Reproductive Technology

摘要

This paper proposes a novel therapeutic approach to control the implantation position after embryo transfer in assisted reproductive technology (ART). The system comprises a microrobot, a catheter, and a guiding magnet. The microrobot accommodates and transports the embryo into the patient’s uterus and maintains its position within an area suitable for implantation. The catheter has a mechanism for catching and releasing the microrobot involving a catch/release sensing system. The utility of the system was successfully demonstrated using a human phantom. This minimally invasive system will increase pregnancy rates and prevent ectopic pregnancy in ART.
