Two modifications of the intrauterine membrane contraceptive device.
The intrauterine membrane (IUM) is an intrauterine contraceptive device designed to be compliant with a range of uterine shapes and sizes and with transient dimensional changes resulting from uterine motility. This compliance was expected to contribute to low rates for removal due to bleeding and pain, but the use of the IUM resulted in heavy bleeding among its early users. Consequently, two modifications of the device were made to decrease bleeding. One group of IUMs was modified by using ethylene vinyl acetate to provide a high level of lateral compliance and another was modified by using a tissue-compatible Hydron coating in order to decrease the inflammatory response of the endometrium. One hundred of each of these modified IUMs were tested along with 100 of the standard IUMs in a double-blind study conducted at the Noi Klinika in Debrecen, Hungary. The findings of this study suggested that these two modifications did not improve the over-all performance of the IUM.
