Catheters, Intrauterine, Ovum Recovery
Definition : Intrauterine catheters designed to perform endometrial irrigation (lavage) to recover preimplanted ova. These catheters typically consist of a dual-lumen 11 Fr Teflon tube with a solid bullet-shaped distal tip; the internal coaxial lumen is for inflow, and the external lumen is for outflow. The lavage fluid is injected into the endometrial cavity over three to five minutes using a syringe; the outflow is facilitated by a negative pressure pump. Ovum recuperation catheters are mostly used to recover fertilized ova from fertile women to be nonsurgically transferred to infertile women.
