Novel Method and Device for Delivery and Retention of Intrauterine Devices in the Immediate Postpartum Period: Pilot Baboon Feasibility Study

The immediate post-partum period offers a convenient time to have an intrauterine device placed because of the co-location of a non-pregnant woman and her clinician; however, this practice is associated with increased expulsion rates of up to 30%, compared with a 3% expulsion rate for interval insertions. This paper presents a device and method to improve intrauterine device delivery and retention in the immediate postpartum period. This initial feasibility study illustrates that it is possible to temporarily tether a commercially available intrauterine device within the uterus of an immediately postpartum baboon. The results indicate this device and method are technically feasible, but further studies will be needed to evaluate safety and efficacy in reducing expulsion rates.
