Definitions
- the invention relates to the technical sector of the means and methods of female contraception.
- the reference method is the device "ESSU E” which implements a reactive inflammatory action. In addition to pose failures, this technique is irreversible. It is an alternative to surgical sterilization and consists of a selective occlusion of the tube with insertion of a micro-spring about 4 cm long in each patient's trunk. Within this micro-spring exist polyethylene terephthalate fibers that elicit a natural tissue reaction that is itself responsible for occlusion. According to the prior art reversible female sterilization devices described in patents EP 0010812, US 2009/056722 which offer the possibility on both sides of a medial tubular portion to have opposing shapes likely to be anchored in the fallopian tube and its mouth. More particularly, in the aforementioned US patent, the device has conical shaped fin shapes for anchoring in the aforementioned horn. These devices do not nevertheless respond to the control of the deterioration of the cellular tissues inside the trunk.
- FIG. 1 for the understanding of the invention thus shows the anatomy of the fallopian tube which comprises four successive parts from the uterus, namely a uterine (a) or interstitial part, the middle part (b) called isthmic portion and the so-called infundibulum part or bulb (c) and the flag.
- the first two parts which are of interest for the invention have respective lengths of 1 to 1.5 cm and 3 to 4 cm.
- the ostial diameter is about 1 mm
- the internal diameter or lumen is 0.2 to 0.5 mm.
- the oocyte diameter is 0.1 mm.
- FIGS. 2, 2a, 2b, 2c show the anatomy of the trunk for the understanding of the invention. Sections A, B and C are established to show at different places of the trunk the different corresponding sections and presentation of the internal structure thereof.
- the peritoneum is identified by 2 the subserosa, 3 the plexiform molecular layer, 4 the annular molecular layer, the vessels, the oval migration corridor and spermatozoa.
- the cells formed in a random manner between haustration or mucosal folds (8) inside the trunk.
- the contraceptive device of the type comprising a shutter with a body of cylindrical configuration or the like made of a flexible material and including two stabilizing means in the form of ribs or fins deformable and foldable along the body of the shutter in non-solicitation situation and spreading radially in the laying position in the part isthmic of the fallopian tube, said means being in opposite positions to come on the one hand in the isthmic part of the trunk (for the distal side), and on the other hand (proximal end) on the edges of the tubular ostium, is remarkable in that the device comprises along the body a plurality of protruding shapes, in a furrow configuration, established over the entire length of said shutter body continuously from the conical bulge of the proximal end to the spherical distal end of the head and having a dual function of a portion of tubal lumen and tubal hare protection said shapes adapting in the cells formed in the body of the trunk and being in contact with some muco
- a protective sheath (playing a launcher role) surrounds the shutter, and is engaged in the isthmic part of the trunk and removed by allowing the deployment and anchoring of the whale or fin shapes to the zones. considered.
- FIG. 1 is a representation of the internal structure of the fallopian tube.
- FIG. 2A, 2B, 2C are schematic views illustrating the anatomy of the fallopian tube, according to different positioning sections.
- FIG. 3 is a schematic view illustrating the device according to the invention, with the longitudinal projections.
- FIG. 4 is a schematic view illustrating the device integrated in a launcher and positioned beforehand in the fallopian tube.
- FIG. 5 is a view according to FIG. 4 after removal of the launcher;
- FIG. 6 is an alternative view of the device with a shifted axis head;
- Figure 6a is a front view and in section according to Figure 6.
- FIG. 7 is a sectional view of the shutter device according to the invention, illustrating in particular its projecting profiles formed on the body.
- FIG. 8 is a view illustrating the device disposed (in the fallopian tube) with launcher in place.
- FIGS. 9 and 10 are schematic views illustrating before and after the positioning of the device in the fallopian tube especially with respect to positioning with mucosal folds and inner cells, with the dual function of obstruction of part of the tubal lumen, and on the other hand protection of part of the haustration or mucous folds.
- the contraceptive device according to the invention is referenced as a whole by (10) and is intended to be introduced into the isthmic part of the fallopian tube (T). It is in the form of a cylindrical obturator having along its length a plurality of protruding protruding forms (10a) having a function of obstruction of the tubal lumen and protection of the tubal mucosa, cooperating with the mucosal folds. (8), filling all or part of the internal volume of the horn defined by the cells.
- the mucosal folds which are in a random situation come for some in contact with the walls of the protruding forms, generating a deformation of the cells to ensure an obstruction to the passage of the spermatozoa.
- protruding shapes (10a) can be arranged regularly along the shutter body with identical spaces. They may alternatively be different and offset relative to each other in an irregular pitch. These protruding shapes can be of the same configuration, and of the same height. Alternatively, these protruding shapes may have an irregular configuration. As shown in Figure 3, the head (10b) of the shutter can be in the axial extension of the body or be shifted substantially to facilitate the introduction of the device into the fallopian tube.
- This shutter is made of a flexible material of the silicone type or other non-recolonizable material, so as not to injure and damage the environmental walls of the tube in which it sits (or any other atraumatic material and which avoids a tissue reaction by fibrosis of the implant).
- the obturator has near its distal and proximal ends two means (1 1-12) having a configuration with whales and arranged in opposite directions from each other. These means (1 1-12) are arranged radially to the body of the shutter and define shapes in whales or fins (1a-12a) deformable and foldable along the body of the shutter in non-solicitation situation before implementation. place in situ. These whales or fins can be manufactured with the body of the shutter in one piece and therefore in the same material.
- the means (12) disposed near the distal end opens on the ampullary side of the fallopian tube, so that it comes to anchor in the surrounding mucosa, and can be folded or at least not interfere in case removal of the contraceptive device.
- the height of the whales is sufficient to anchor in the mucous membrane.
- the second anchoring means (1 1) is on the proximal side of the shutter.
- the protruding shapes (10a) are established over the entire length of the obturator body from the tapered bulge of the proximal end to the distal end of the head 10 (b) and continuously. These protruding shapes have a furrow configuration whose continuous base is the body of the shutter.
- said proximal end has an opening (17) for passage and introduction of a cord or other means to allow removal of the device if there is a desire to pregnancy.
- the introduction of the device into the isthmic part of the tube is done by introducing previously in a sheath (15) which causes the application of the means (1-12) along the body of the shutter. Then under the pushing effect of a pusher (16), the obturator device will be released in the isthmic part of the fallopian tube by removing the sheath by a push-back effect and the means (1-12). will unfold radially and become anchored.
- the installation of the contraceptive device according to the invention is carried out under the control of vision with a hysteroscope.
- a mark (13), FIG. 5, of any material, intended to be identified and located by a reading means of the type used in ultrasound and in standard radiology, is placed on the device (10).
- the device is located behind the first means (1 1).
- the device further comprises a withdrawal means (17) in the form of a gripping orifice disposed behind the anchoring means (1 1) and allowing said withdrawal.
- the means (1 1) at the distal end has umbrella-shaped ribs of a size smaller than that of the means (12) disposed at the proximal end.
- the advantages of the contraceptive device according to the invention reside in the quality of the obturation given by the body of the shutter, thanks in particular to said protruding shapes (10a) which ensures a perfect seal with respect to the inside of the body. fallopian tube.
- all the mucosal folds and all the cells are not systematically in contact with the obturator tube and its protruding forms (10a), which leaves in case of deterioration, the possibility of cell migration and regeneration to restore the damaged cells after removal of the device.
- the design of the device according to the invention makes it possible to create folds of tubal mucosa which is a source of protection for the mucosa and a source of repair of the folds that have been in contact with the device.
- This method of contraception is reversible by allowing the removal of the shutter device easily and without anchoring resistance by the orientation of the anchoring means (1 1) and the specificity of the shapes (10a) inside. of the trunk.
