1. An intra uterine device comprising an elongate conformable member with at least a portion including a contraceptive agent having shape memory adapted to conform into a predetermined three dimensional configuration formed by at least two loop-like structures approximately perpendicular with respect to each other when released from a hollow sleeve positioned within a uterine cavity, wherein a first plane defined within a first loop-like structure crosses through a second and approximately perpendicular plane defined within a second loop-like structure, and wherein said three dimensional configuration is capable of elastically contracting and expanding in response to contraction and expansion of said uterine cavity thereby enabling said three dimensional configuration to maintain its position within said uterine cavity, wherein the elongate conformable member has a proximal end and a caudal end and is configured to be linearized in the hollow sleeve into a single straight elongate conformable member having the proximal end at one end of the sleeve and the caudal end at the other end of the sleeve and is configured to be introduced from the sleeve into the uterine cavity to assume the predetermined three dimensional configuration.
