Abstract: An intrauterine device string is described. The intrauterine device string includes an elongated member with an upper portion, an intermediate portion, and a lower portion, the elongated member comprising a memory-retaining material. The upper portion is configured to attach the elongated member to the intrauterine device, and the intermediate portion is configured to extend through the endocervical canal of a female. The lower portion comprises a first curved portion and a second curved portion at an end of the lower portion. The lower portion is configured to prevent the elongated member from becoming dislodged when in use in a female, and is further configured to apply a force to the external wall of a cervix. A method for inserting an intrauterine device is also disclosed.

Abstract: An intrauterine device string is provided. The intrauterine device string has an elongated member with an upper portion, an intermediate portion, and a lower portion. The upper portion is configured to attach the elongated member to an intrauterine device. The intermediate portion is configured to extend through the endocervical canal of a female. The lower portion has a first curved portion configured to follow a contour of the external orifice of the cervix of a female. A second curved portion at an end of the lower portion has a memory-retaining material to prevent the second curved portion from passing through the external orifice of the cervix and to constrain the second curved portion to follow the contour of the outer portion of the cervix. The intermediate portion is configured to pass through a plane defined by three points on said second curved portion when in use.

Abstract: The present invention relates to an intrauterine device string for attachment to an intrauterine device fitted within a female, the female having a cervix comprising an endocervical canal and an external orifice, the intrauterine device string comprising an elongated member with an upper portion, an intermediate portion, and a lower portion; wherein said upper portion is configured to attach said elongated member to the intrauterine device, wherein said intermediate portion is configured to extend through the endocervical canal, and wherein said lower portion comprises a first curved portion configured to follow a contour of the external orifice of a cervix; and a second curved portion at an end of said lower portion configured to prevent said second curved portion from passing through the external orifice of the cervix.
