Definitions

  • the present invention relates to a contraceptive [30] Foreign Appli ation Priorit D t device to be placed both in the uterine cavity and in i the uterine neck and comprising on the one hand a Dec. 15,1970 France ..7045235 hollow cylinder provided with one or more windows 52 us. Cl ..128/130 128/260 its side wall and with a widening at its upper 51 int. Cl.
  • a novel device which acts both on the wall of the uterine cavity and the cervical wall, the part of said device which acts at the level of the uterine cavity not being flat as in the prior art.
  • the device according to the invention which comprises a pair of supple, curved stems located in the same plane, the upper ends of which are folded back, in opposite directions, and a supple stem folded back on itself forming a loop, the assembly of said stems being intended to be disposed inside the uterine cavity, is characterized in that said pair of stems, the loop and a second pair of stems similar to the first pair, but angularly shifted with respect thereto, are housed, by means of their lower ends, inside a hollow cylindrical tube intended to be placed inside the neck of the uterus, which tube is widened at its.
  • the pairs of stems and the loop being in planes parallel to the axis of said tube, and in that the loop is provided at its summit with an excrescence which is substantially perpendicular to the plane of said loop.
  • the assembly constituted by the loop and the two pairs of stems is intended to occupy the greater part of the space of the uterine cavity.
  • These stems are preformed in such a manner that they are deformable rectilinearly by the application of a force, in order to enable the doctor to place and remove the device according to the invention.
  • a device By the combination of the loop and the two pairs of stems, a device is produced, the part of which that is intended to act at the level of the uterine cavity, is in the form of a lily.
  • the tubular cylinder is intended to permit the menstrual flow of blood.
  • the widened form of the end where the stems are assembled is placed at the level of the uterine isthmus. This widening is preferably oval or elliptic in section, so that the isthmic region is not obturated, but favors the flow towards the neck.
  • the hollow tube is also preferably oval or elliptic in order to ensure said flow.
  • the side wall of the tubular cylinder there are arranged at least two windows, and preferably three, depending on the dimensions of the intra-uterine devices, as will be seen later. It is an object of these windows and the shape of the section of the hollow tube to avoid excess pressures inside said tube which would favor the ejection of the device, since the loop and the pairs of stems forming the lily would penetrate into the cylindrical tube and would no longer ensure its holding in the neck.
  • the tubular cylinder disposed in the cervical region creates a zone of diffusion of acidity at the level of the cervical glair, rendering it spermifugal. It is known that the spermatozoa flee from acidity, particularly that of the vagina, and rise in the neck where they meet an alkaline medium. Due to the presence of a hollow cylindrical tube provided with two or three windows, held in the neck, the cervical glair becomes acid and remains impassable to the spermatozoa.
  • the hollow tube is provided with an acid cream or jelly, with a pH of about 4.5 5 introduced through the base of the tube, in order to encourage the diffusion of acid ity at the level of the cervical glair.
  • the most suitable spermicidal jellies and creams that may be used are those which comply with the control criteria of the International Planned Parenthood Federation.
  • the acid cream is generally introduced through the lower aperture of the cylindrical tube and the acidity must be checked every 4 or 6 months in order to determine the moment of replacement. This check can be effected by means of a pH indicator paper.
  • each of the stems of the pairs of stems is integral with a side part of the loop.
  • the loop and said pair of stems are preferably located in the same plane,
  • the excrescence provided at the summit of the loop may be spherical or preferably cylindrical.
  • said excrescence is a cylinder
  • the face: of the upper section of said cylinder is provided with a groove so as to render the contraceptive device more supple.
  • Such a device due to its lily shape, avoids having to fix the hollow tube to the edge of the neck of the uterus by one or more stitches.
  • a fixing means integral with the hollow tube on which possible stitches will be made may be provided.
  • This fixing means may, according to a particular embodiment of the invention, be a tongue-shaped member provided at the lower end of the hollow tube, in the form of an arc, and intended to cover the edge of the uterine neck as far as the stitch.
  • this fixing means may be a pastille or excrescence provided on the outer wall of the hollow tube at the lower end thereof, the stitches then being effected if necessary on the inner edge of the opening of the neck.
  • This latter mode of fixation has two advantages: for the doctor, it is much more practical to make the stitches at the level of the inner edge of the opening of the neck than to make them on the outer edge of said opening, on the one hand, and, on the other hand, such a mode of fixation enables the dimensions of the fixing means to be reduced.
  • the material used for making the device according to the invention is generally a synthetic macromolecular substance chosen in particular from polyamides, polyesters, polyfluoroalkylenes and polyolefins which do not irritate the tissues and have a high resistance to the attack of the enzymes of the tissues. If desired, 20 percent by volume of barium sulphate may be incorporated in the macromolecular substance, in order to render it opaque to X-rays.
  • the stems and the tube may be made of polypropylene.
  • the stems and the loop are introduced into the uterine cavity by means of a pusher made of flexible plastics material, particular polystyrene, provided with a flat part at its upper end in order to facilitate the positioning, as it is necessary for the stems and the loop in the form of a lily to be suitably adapted to the size of the uterine cavity in order to ensure a sure contraceptive effect.
  • a pusher made of flexible plastics material, particular polystyrene, provided with a flat part at its upper end in order to facilitate the positioning, as it is necessary for the stems and the loop in the form of a lily to be suitably adapted to the size of the uterine cavity in order to ensure a sure contraceptive effect.
  • FIG. 1 shows a contraceptive device
  • FIG. 2 is a section along II-II of the device of FIG. 1.
  • FIG. 3 shows a device similar to that of FIG. 1.
  • the contraceptive device according to FIG. 1 is composed of a hollow cylinder 1 of oval or elliptic section provided with windows 2 of 1 mm by 0.37 mm and with a widened sleeve 3 with a height of 3 mm and upper diameter of 3 mm.
  • Four curved stems 4 leave this sleeve, the free end 5 of each of which is folded back on itself and is provided with a spherical excrescence and a stem curved back on itself forming a loop 6, the loop having at its summit a substantially ellipsoidal excrescence.
  • a fixing tongue 8, in the form of an are, connected to the contraceptive device, preferably along the lower third of the hollow tube, is fixed to the outer edge of the neck at a point 9 of the periphery of the neck.
  • the fixing at 9 is effected by passing the tongue 8 into the neck by means of a needle; 2 to 3 knots are generally necessary.
  • the curved stems 4 are cylindrical and have a diameter of 0.5 mm, the loop 6 is also cylindrical with a diameter of 0.5 to 0.75 mm, the excrescence 7 is 2 mm high and 4 mm long.
  • FIG. 3 shows a preferred contraceptive device, which differs somewhat from that of FIG. 1 in that one of the stems 4 of each pair of stems is integral with a side part of the loop 6, said stems and said loop being located in the same plane parallel to the axis of the hollow tube.
  • the cylindrical excrescence 7 has a groove on the face opposite the face of contact of said excrescence with the loop.
  • the arcuate fixing tongue of FIG. 1 is advantageously replaced here by a pastille or excrescence 8 provided at the lower end of the hollow tube and intended for making stitches on the inner edge of the opening of the uterine neck.
  • the largest internal diametrical dimension of the cylindrical tube 1 may vary between 2 and 2.5 mm and the largest outer diametrical dimension between 3.3 and 4 mm.
  • the length of the tube and the height of the stems-loop assembly intended to occupy the intra-uterine cavity depend upon the clinical examination made by the doctor.
  • the cylindrical tube preferably has a length of between 22 and 47 mm.
  • the tubes intended to be lodged in the cervical part will preferably be supplied with the following four lengths: 22mm, 32mm, 37mm and 47mm.
  • a Charriere gauge 10 or French gauge 10
  • a Charriere gauge 12 or French gauge 12
  • an inner end diameter of 2.5 mm and outer end diameter of 4 mm will be used with an inner end diameter of 2.5 mm and outer end diameter of 4 mm.
  • the extreme width of the device according to the invention, inside the uterine cavity, varies between 16 and 26 mm.
  • Contraceptive device to be placed both in the uterine cavity and in the neck of the uterus and comprising a hollow cylindrical tube, a first pair of supple, curved stems located in the same plane and the upper ends of which are folded back in opposite directions, a second pair of stems similar to said first pair of stems but angularly shifted with respect thereto, and a supple stem folded back on itself, forming a loop, wherein said first and second pairs of stems and said loop are housed, by means of their lower ends, inside said hollow cylindrical tube, intended to be place inside the neck of the uterus, which is provided with a widening at its upper end and with one or more windows on its side wall, the pairs of stems and the loop being in planes parallel to the axis of said tube, and the loop is provided at its summit with an excrescence substantially perpendicular to said loop.
  • each of the stems of a pair of stems is integral with a side part of the loop, the loop and the stems to which it is connected being located in a plane parallel to the axis of the hollow tube.
