CZ134191A3 - Contraceptive corpuscule for reversible sterilization - Google Patents

Abstract

The blocking body closes the passage through the fallopian tube and is inserted there and left there for the decided sterilization time. The inserted blocking body is removed from the fallopian tube to restore fertility. The blocking body dilates spontaneously after insertion into the fallopian tube and closes the passage through the fallopian tube. After insertion of the blocking body made with admixture of a sonographically or by X-rays detectable compound into the fallopian tube the insertion is checked by X-rays or sonographically.

Description

The invention relates to contraceptive devices for reversible sterilization of women.

The prior art sterilization mostly resulted in irreversible sterilization, for example by ligature of the fallopian tubes through the abdominals to carry out this anesthesia, which is irreversible when there is maternity. The same by interrupting the fallopian tube

The methods used so far practically irreversible,

Sterilization was performed by screening, burf laparotomy or laparoscopy. Despite the necessity of relatively serious surgery and surgery in a disadvantageous method, especially due to his wife, pregnancy is still impossible and the sterilization by diathermocoagulation by laparoscopy has consequences.

Again, it is a relatively severe surgery under anesthesia, costly and very serious for a woman.

Heavy barrier methods of contraception using various types of pessaries are known. introduction before each contact, using this method. Plus

Their considerable disadvantage is the necessity which greatly limits the possibility that not every woman is able to learn and reliably implement the introduction of a pessary. For a certain number of women, the allergy to the material from which the pessary is made is also added. This allergy also occurs in the case of using a condom by a man, for whom such a method of contraception constitutes complications and renders the woman dependent on the male i.

ve

It is also known to use intrauterine devices which are introduced by the physician into the uterine cavity. However, this method does not provide reliable contraception in all cases because of its not 100% efficacy. In addition, it carries the risk of side effects, particularly inflammation and bleeding.

The use of hormonal preparations for contraceptive purposes requires regular use to guarantee the necessary efficacy. In a number of cases, this method has to take into account undesirable side effects and consequences, often occurring after a long time and causing harm to the woman's health.

In summary, the prior art methods and means for performing contraception or sterilization are always disadvantageous. Either irreversible sterilization is prevented, preventing pregnancy permanently, regardless of the difficulty and severity of the procedure causing permanent blockage of the fallopian tube, or the contraceptive method used offers the possibility of complications and side effects. The effectiveness of many contraceptive methods is not 100%.

SUMMARY OF THE INVENTION

These drawbacks are virtually eliminated by the reversible sterilization contraceptive body of the present invention. It is formed by a rounded intratubal insert of hydrophilic swelling gel.

According to a further preferred embodiment of the invention, the contraceptive body in the form of a rounded intratubal insert is provided with a handling thread fixed therein and led out.

In insertion, the rounded intratubal insert is positioned at the end of the flexible catheter in front of the flexible siandren introduced into the cavity of the flexible catheter.

Preferably, the rounded intratubal insert is a hydrophilic swelling gel stick.

Alternatively, it can be made as a roll of hydrophilic swelling gel.

For easy detection of the established contraceptive device, the rounded intratubal insert is then alternatively provided with a sonographic or X-ray detectable substance.

The contraceptive device for reversible sterilization according to the invention is readily practicable, is inert, does not cause any side effects and its efficacy at the same time is 100% when used on both fallopian tubes. It is also easily removable. In addition to its cheapness, its advantage is the undemanding nature of the sterilization method.

BRIEF DESCRIPTION OF THE DRAWINGS

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 illustrates the first phase of introducing a contraceptive body according to the invention into argards; FIG. 2 represents a further stage; FIG. 3 shows a body already in place; FIG. and FIG. 5 shows a detailed enlarged cross-section of the contraceptive body according to the invention.

examples and embodiments of the invention

Figures 1, 2 and 3 illustrate the introduction of the contraceptive body of Figure 5 with the aid of the means of Figure 4. A flexible catheter 1 is used in which a flexible mandrel 2 is inserted in the cavity 2 i®. The maximum outer diameter of the flexible catheter 1 must correspond to the possibility of its insertion into the mouth of the fallopian tube. the end 'allowed the insertion of a rounded intratubal insert 4.

The intratubal insert 4 preferably has the shape of a short rod or a cylinder with rounded ends. A handling thread 5 is led out there. The handling filament 5, preferably of mersilk, has its attachment in the intratubic insert 4, for example, by providing knots 6 which are attached to the intratubic insert 4 during its forming, eg by casting or spraying into the mold, where the handling fiber 5 into the intratubal insert 4. However, the fixation of the handling fiber 5 can also be performed differently, eg by enlargements of its cross-section made on the handling fiber 5 during manufacture. The intratubal insert 4 is made of a hydrophilic swelling gel.

The introduction of the contraceptive body is carried out by inserting a flexible catheter X into the mouth of the fallopian tube 8 with the aid of a hysteroscope (not shown) in the uterine cavity 7, in the continuous cavity 2 of which at the end before the flexible mandrel 3. saved. After insertion of the resilient catheter X through the vagina 2 and the uterine cavity 7 into the mouth of the fallopian tube 2 (Fig. 1), the resilient catheter X begins to be pulled out while being held or held by the flexible mandrel 3. The intratubal insert 6 is pushed into the fallopian tube 3 with sensation without feeling of resistance, which can remain in the place of delivery. After the flexible catheter X has been pulled out of the uterine cavity, the flexible mandrine 2 and resp. the flexible catheter X and the flexible mandrine 2 are pulled out after the flexible catheter X is withdrawn from the fallopian tube 3 while holding the intratubic insert 4 in place, and then the flexible mandrel X can be pulled out with the flexible catheter X extended. On day 11, the intratubal insert 4 of the hydrophilic swelling gel swells so as to completely close the passageway to the fallopian tube Q, since it closely fits to its walls. The same procedure applies to the second fallopian tube 8, if it is functional. The handling thread 3 is then shortened to the required length.

íS

The intratubic insert 4 remains in the fallopian tube 8 for the desired period of time and reliably prevents the penetration of semen to the fallopian tube because it closes the passage through the fallopian tube 8 in its swollen condition. Its correct insertion can advantageously be checked by X-ray or sonographically barium. In order to cancel the sterilization to restore fertility, the intratubic insert 4 is pulled out of the handling fiber 5, which is also carried out in the second fallopian tube 6.
