Intrauterine device of C or omega form
First Claim
1. 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 having a plurality of surface serrations and 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 a metallic wire contraceptive agent wound around the member between serrations, whereby the coils of the wire are spaced apart and maintained in position.

Abstract
An intrauterine contraceptive device made from plastic having a C-shape or Omega-shape to enable it to lie in the uterine cavity. Lines of predetermined length are attached at one of their ends respectively to enlargement portions of the terminal ends of the device and with their other ends fastened by a plastic bead and aid in insertion, removal and as a telltale marker. The device can include a metallic contraceptive material such as copper. One embodiment uses copper wire, which can be of selected different diameter, wound on the body of the device and retained against slippage by serrations on the body. A tubular inserter with appropriate grips and a cervical abutment flange is used to receive the IUD in elongated deformation. The device is slipped through the tubular inserter by a plunger and as the IUD emerges from the upper end of the tube, strain on one of the lines caused by abutment of the bead on the lower end of the tube positively bows and pulls the emerging IUD into a substantially circular configuration within the plane of the fundal cavity, the inserter having been appropriately oriented during the preliminary insertion steps.
