Intrauterine device of C or omega form

A linear type of intrauterine contraceptive device made of flexible material comprising:

• an elongate member which, in situ, assumes a linear arch-shape wherein the two terminal portions of the linear form are connected by a noninterrupted continuous arch form, and the terminal portions curve inwardly toward each other providing incurved, oppositely directed linear portions in opposed relationship at each end of the arch form disposed in substantially linear alignment, in situ;
• said member being of material with sufficient flexibility to assume a substantially straight linear form to accommodate insertion, and thereafter assume the arched, in situ, configuration, which has dimensions substantially encompassing an area enabling the device to be contained within a normal uterus;
• and at least a part of the surface area of the device comprising copper wire as a contraceptive agent wound around at least part of said member, the surface area of the wire being in the range between 200 to 450 sq. mms.

• and at least the arch portion of said member having a boundary surface comprising a pair of spaced apart inner and outer surfaces being connected at their adjacent sets of ends by convexly curved surfaces, and in transverse cross-section the dimension between said spaced apart inner and outer surfaces being less than the dimension between said convex connection surfaces.
