Abstract: A plunger intended for an inserter for an intrauterine device with a T-body, which plunger has a first end and a second end. The plunger's length in its longitudinal direction is substantially larger than the diameter of the cross-section perpendicular to the longitudinal direction. The plunger's cross-section is substantially circular. An opening (17) has been arranged in the plunger's longitudinal direction so that the opening's longitudinal axis is substantially the same as the plunger's longitudinal axis. The opening at the first end of the plunger is arranged to expand in a direction perpendicular to its longitudinal axis to form a tip portion, so that the tip portion has at least one surface (6, 7, 8, 9, 10, 11), which along at least a portion of the tip portion's length turns at least 35° in relation to a first plane in parallel with the longitudinal axis and at least 35° in relation to a plane at an angle in relation to the longitudinal axis.

Abstract: A contraceptive method of inducing ovulation in induced ovulation mammals, in particular the female cat, by stimulating mainly the cervical region of the vagina to trigger a cascade of hormonal reactions to cause ovulation and pseudo-pregnancy to eliminate the unwanted behavior of female cats in heat. The treatment consists in the introduction of an ovulator inside the vaginal cavity of the animal. This apparatus is similar in shape and size to the penis of a cat, is made of a soft flexible material and is safe and easy to clean. The method imitates the sexual behavior of cats by causing a repeated number of brief stimulations at the peak of the estrus cycle.

Abstract: A drug comprising either a peptide having the LH-RH action or an LH-RH antagonist is carried on an intrauterine contraceptive device (IUD) so as to be able to provide controlled release. Once the IUD is put in the uterus, the carried drug is gradually released over such a prolonged period of treatment time as, for example, several months to be continuously absorbed through the uterus mucosa or the vagina mucosa. This construction makes it possible to reduce the patient's pain and such a troublesomeness as frequent drug administration and continuously administer a necessary drug over a prolonged period of time while taking a contraceptive measures.

Moreover, the improved tampon can be impregnated at select depths with specific spermicides, anti-infectives, lubricants, hormones, antioxidants, amino acids, etc., to allow release of inner-impregnated fluids from the member into the body cavity. Closely controlled impregnation and/or coating of the tampon is achieved by a method of manufacture employing one or more sonic baths containing necessary impregnating and/or coating fluids.

Abstract: Methods and apparatus are disclosed for permitting a user to load an IUD into an IUD inserter within the confines of a tray and thereafter to safely insert the IUD into a patient's uterus to the proper depth while minimizing the risk of causing trauma to the uterine wall. An IUD inserter comprises an elongate shaft adapted to retain the arms of an IUD adjacent the distal end of the shaft, a slidable arm retainer mounted on the shaft adaptable to abut the outer portion of a patient's cervix, and a stop member adjustably mounted on the shaft so that the arm retainer is forced by the outer portion of a patient's cervix to abut the stop member as the IUD is advanced through the cervical canal of a patient to a preselected depth at the uterine fundus. An associated package permits an IUD having expandable arms thereon to be loaded into an arm retainer within the confines of the package immediately prior to insertion of the IUD into a patient's uterus.

Abstract: A cervical pressary having a central stem with a passage from end to end thereof. A distal retainer is provided at the distal end of the stem, and a proximal retainer at the other end. The retainer are flexible and distensible. They are connected to each other through the stem passage, and are inflatable by fluid injected into them. A leaflet-type fill valve passes through the wall of the proximal retainer. Th fill valve closes when outside pressure is exerted on the leaflets. The fill valve can be physically opened by insertion of a fill tube into it.

Abstract: An intra-uterine pessary includes two spreading arms which are in a folded configuration for insertion through the cervical canal and assume an unfolded configuration for retention in the uterine cavity. The two spreading arms form a substantially closed-loop structure in the folded and in the unfolded configuration. The spreading arms are traversed by a third arm which is connected to the spreading arms and to an abutment mounted on the spreading arms. The length of the third arm is changeable. The two spreading arms are made exclusively of a metal wire and are straightened in the folded configuration and have an annular shape and are elastically bent in the unfolded configuration. The length of the third arm can be finely adjustably controlled when the spreading arms ae in the unfolded configuration.

Abstract: A one-hand apparatus for insertion and fixation of an IUD which has a penetration member with a needle at the distal end for holding an attaching member of an IUD. The penetration member with the IUD are slidably received and positively locked within an insertion tube to prevent slidable movement of the needle during initial insertion to touching contact of the insertion tube with the fundus. Thereupon, the penetration member is released by thumb action of the user upon a lock/release member to allow penetration of the needle into the fundus by a predetermined distance to fix the IUD to the fundus.
