Abstract

An intrauterine device for applying force to a wall of a uterus to promote contraception without blocking the fallopian tubes may include an elongate member formed of a resilient material and having a default expanded configuration and a spring portion disposed approximately at a midpoint between two ends of the elongate member. The IUD may also include two tissue contact members, one tissue contact member disposed at one of the two ends of the elongate member and the other tissue contact member disposed at the other end. The tissue contact members may generate a laterally directed force against the wall of the uterus when the intrauterine device assumes its default expanded configuration.
