Abstract: An instrument 10 to prepare an intra-uterine device 30 for insertion in uterus 50 of woman, comprising a downfolding device 20, a graduated tube 16, a push rod 17, a stopper 15, and an IUD 30; the downfolding device 20 having a concave depression 41 on either side, an open channel 29 of a circular orifice 46 having a sector of angle measure 46A at least 220° and having an exit opening 48 initially marginally less than an external diameter 22B of the graduated tube 16, a root thickness 37B of the base 37 in-between the open channel 29 such that the exit opening 48 increases by the base 37 flexing; the graduated tube 16 has an internal diameter 22D of a far-end opening 22a of the graduated tube 16 sufficient to capture the stem 33 and both arms 32 of the IUD 30 in a downward triangular formation 51.

Abstract: A combination current sensing device comprising a plurality of current measuring sensors, at least one ambience measuring sensor, a voltage measuring device and a computing device; at least a magnetic field concentrator, and a controlled module assembly constraining the magnetic field concentrator and the bar conductor, in a defined position with respect to one another; the combination current sensing device may have a plurality of incoming connections and a plurality of outgoing connections; and the computing device outputs a validated measure of primary current and an auxiliary information according to a plurality of range and a safe value of the primary current, ensuring functional safety. The voltage measuring device determines a voltage, configured functions and health of an electric source in combination with other sensors and the computing device. One or more of the devices may be optional and or external to the combination current sensing device.

Abstract: An intrauterine device (IUD) with a restricted movement of a string(s), the strings can be either a single string or two or more strings or a filament, emerging from the spherical bulge of IUD. The strings of IUD are of a differential strength so that the strings are soft and the hanging portion of the strings, “feelable” in the vaginal cavity, does not cause discomfort to the woman, nor bruise the organ of the partner during intercourse, at the same time the strings in the endocervical canal are relatively stiffer and not have the tendency to get curled up progressively. The strings optionally have marks to facilitate cutting by a surgeon to an accurate length.

Abstract: An intrauterine device (20) with a restricted movement of a knot (5) of the string (4) due to a region (3) having such differed shape and size at a distal end (12) of central vertical stem (1) and due to a trajectory for string (4) in the region (3) that the length of the string (S) is shorter than the distance (r) of the region (3); and the loop (15) of the string and therefore the knot (5) is unable to pivot around the axis (14) . The lateral shift of the knot (5) is also prevented. Consequent to restricted pivoting and restricted lateral shift of the knot (5), the hanging portion (9) of the string (4) continue to project downwards and do NOT develop tendency to get retracted and thus do not curl up in the uterus (16) through the cervix (17).

Abstract: A process and an apparatus for loading, insertion and placement of an intrauterine contraceptive device (IUD) for its proper and hygienic placement in the uterus, the apparatus in a sterile pouch having a transparent cover and a base; the apparatus having a loader with a passage having a first opening and a second opening running along its elongated body, a graduated tube mounted onto loader through its second opening, an IUD and a push rod miming inside the graduated tube. The IUD is parked in the loader in an expanded condition, required to maintain inside the uterus. The loader has a guide means forming the front portion of the loader and pusher means forming rear portion of the loader. A platform connects the guide means and the pusher means of the loader. The passage runs along an elongated body of the loader.

Abstract: An embodiment in accordance with the present invention provides a loading, inserting and releasing tool for T-shaped intrauterine device (IUD) into a uterus. The loading tool comprises a shaft member having a loader, an inserter tube, an IUD and a plunger. The loading tool includes a platform configured at a proximal end of the loader for holding the IUD in an open position, and an elongated member extending from the platform. The elongated member includes a slot running therethrough aligned to the opening of the loader. Further, the loading tool includes a plunger within an inserter tube capable of running through a slot provided with markings thereon. The inserter tube is provided with a knob for pushing the inserter tube along with plunger in forward and backward direction for inserting and releasing the T-shaped IUD into the uterus.
