Intrauterine 3-dimensional device and system thereof

An intrauterine 3-dimensional device (100,200,800) comprising:

• a. a self-expandable anchor (104) portion provided from a slotted-tube made of super-elastic or shape-memory material;
• the self-expandable anchor having an elastic three-dimensional spherical structure formed from a plurality of ribs (104a), wherein when the self-expandable 3-dimensions shape anchor is deployed inside the uterus and radially expanded, said 3-dimensions shape anchor has peripheral retention against the uterus wall to prevent displacement and/or migration and/or expulsion of the intrauterine 3-dimensional device out of the uterus;
• b. a pulling member (108) functionally coupled to a proximal end (106) of the self-expandable anchor (104) to enable pulling and removal of the intrauterine 3-dimensional device out of the uterus;
• wherein the anchor (104) is axially expanded to assume a wider structure (100b) to resist expulsion from the uterus when being pushed by the uterus forces;
• and
• wherein the anchor is radially collapsible to assume a narrow configuration (100a) to allow removal from the uterus when being pulled out with said pulling member (108).
