Abstract
The device occupies the uterine cavity and has two upper smooth rounded ends, each will obliterate the corresponding uterine opening of the fallopian tube at its site of entrance into the uterine cavity. The device has a rounded lower end (curved back on itself) such that the risk of expulsion and displacement will be negligible. The device has no projecting points - and all the areas of contract between the present device and the endometrium are smooth. The device can be designed in other shapes from that shown in Figure 2 and in different sizes as long as it accomplishes the main characteristics of the present device. <IMAGE>
Description
SPECIFICATION
An intra-uterine contraceptive device
This invention relates to an intra-uterine contraceptive device. Intra-uterine contraceptive Devices are well known means of mechanical contraception.
Very many plastic Devices have been devised in the last decade, shaped to provide easy introduction as well as retention in the uterus. The mechanism whereby the devices prevent pregnancy is not agreed. They do not obstruct the ascent of spermatozoa. Spontaneous extrusion of the device and incidence of pregnancy (intra-uterine and ectopic) are not uncommon among the available devices, in addition to excessive blood loss.
According to the present invention, the spontaneous extrusion and the incidence of pregnancy will be negligible and blood loss minimal.
1. The present device has two upper smooth rounded ends that will obliterate the uterine openings of the Fallopian tubes at their sites of entrance into the uterine cavity, preventing the passage of spermatozoa along each respective oviduct, as shown in Figure 1. In addition, copper has been added at both ends, also to act as a spermicidal so the possibility of pregnancy (intra-uterine and ectopic) are negligible.
2. The present device has a rounded lower end that can be fitted in such a way, in contrast to the projecting lower ends of the conventional devices, that the spontaneous expulsion will be remote. See Figures 1,2,3 and 4.
3. The present device has no projecting points that might cause injury to the cervix or the endometrium, therefore the endometrial reaction will be minimal, causing blood loss to be lessened. In fact, all the areas of contact between the present device and the endometrium are smooth.
4. The present device can be designed in any shape as shown in Figures 2, 3 and 4 and in different sizes as long as it accomplishes the main characteristics of the present device.
5. Copper can be added to the two upper rounded ends as well as to the stem of the device as shown for example in Figures 5, 6 and 7. So there will be more surface area covered with copper and therefore the spermicidal effect will be strengthened and the efficiency of the device as a contraceptive will be at a maximum.
6. As it is not uncommon for the thread of the conventional device to become lost, the present device can have two threads. These can either be attached to the lower end of the device or each thread can be attached to the respective upper rounded end.
7. The present device is inserted through an applicator and is easily removed by simple traction of the thread/threads.
Claims (5)
1. A contraceptive device which occupies the uterine cavity. The lower end of the device is rounded such that the risk of expulsion and displace- menu will be negligible.
2. A contraceptive device as claimed in claim 1, wherein the upper two smooth rounded ends of the device each will obliterate the corresponding oviduct at its site of entrance into the uterine cavity so that it will prevent the passage of the spermatozoa along each respective oviduct.
3. A contraceptive device as claimed in 1 or 2, wherein the device has no projective ends towards the endometrium and the areas of contact between the device and the endometrium are smooth.
4. A contraceptive device as claimed in any preceding claim, wherein cupper can be added to the upper rounded ends and/or to the lower part of the device so that the efficiency of contraception will be at a maximum.
5. A contraceptive device as described herein with references to Figures 1-7 of the accompanying drawings.
