The various embodiments of the present inventions provide stabilization devices and methods for use of the stabilization devices with minimally invasive gynecological procedures such as methods of preventing pregnancy by inserting intrafallopian contraceptive devices into the fallopian tubes

A contraceptive device for placement in a fallopian tube includes expanding distal and proximal anchor members and an expandable elongate member connecting the distal anchor member to the proximal anchor member. An expandable material is disposed on at least a portion of the contraceptive device, whereupon delivery of the contraceptive device, the expandable material expands to completely occlude the fallopian tube. The expandable material may contain a drug, therapeutic agent, or hormone which is released over time to occlude or otherwise prevent the passage of spermazoa through the fallopian tube, or prevent ovulation. The contraceptive device may be delivered non-operatively and provide complete sterilization within a period of days. The device and delivery method obviates the need for follow-up visits to confirm closure of the fallopian tubes.

A method for promoting contraception by placing a contraceptive device within a uterus without blocking fallopian tubes may involve advancing a distal end of a delivery device through a cervix, advancing the contraceptive device comprising an elongate shape memory member out of the distal end of the delivery device and into the uterus, and limiting inferior migration of the contraceptive device within the uterus. Inferior migration may be limited by allowing the contraceptive device to assume a shape, when subjected to pressure that tends to cause a downward migration of the device within the uterus, in which an expandable middle portion of the device is expanded to contact the inner wall of the uterus and thus limit the downward migration of the device.

An abbreviated condom that does not exceed the neckline of the penis. The present invention provides a secure contraceptive device, yet it still allows for the increased pleasure and the natural feeling for both people during intercourse. The present invention has an adhesive application that secures it around the head and neck of the penis, which prevents seepage of semen, it prevents the present invention from slipping off the penis during intercourse and it provides strong support to avoid breaking and tearing of the present invention. The tip of the present invention provides a narrow and closed end configuration with ample room on the closed end to collect seminal fluid. Following the tip, the present invention widens to fit over the glans of the penis. The present invention aids in the prevention of pregnancies and spread of STDs.

The present invention provides a condom with a wearing aid comprising a natural or synthetic rubber condom and a wearing aid, wherein, when the outer peripheral wall of the condom is rolled up from the open end of the condom toward the closed end thereof so as to be turned inside, a band-shaped elastic material is stacked on the outer periphery near the open end and rolled up together into the inside of an rolled-up part, where the elastic material is selected from (1) a band-shaped elastic high polymer material, as Material A provided with a number of cut off aperture parts or a number of cuts almost orthogonal to the longitudinal direction of the band, or (2) an expandable bandage or an band-shaped non-woven stretch fabric as Material B.

It includes the following several portions: shell body, cover hinged with the shell body, timing knob mounted on the shell body, low-range switch, medium-range switch and high-range switch, indicator, transformation rectifier mounted in the shell body, display circuit board, timing circuit board and electric circuit board. Said invention also provides the connection mode of all the above-mentioned portions, and also provides its working principle and concrete operation method.

The invention discloses a cervical contraceptive device which contains a traditional Chinese medicine which is prepared from a medicinal herb of radix polygalae and used for killing sperms. The cervical contraceptive device comprises a circular tube bracket. The wall of the circular tube bracket comprises two layers, i.e., an outer layer which is a meshy wall braided with Nitinol wires and an inner layer which is a methyl vinyl silicone rubber layer with a thickness of 0.5mm to 1mm; one end of the circular tube bracket is provided with a first fixed circular ring, the other end of the circular tube bracket is provided with a second fixed circular ring; a slow-release suppository prepared from the medicinal herb of radix polygalae is installed in the circular tube bracket; the slow-release suppository prepared from medicinal herb of radix polygalae takes the shape of the head of a bullet, and a clearance is set between the outer perine of the slow-release suppository and the inner wall of the methyl vinyl silicone rubber layer; and a suppository fixing mesh is installed in a position in which the outer end of the second fixed circular ring is connected with the outer wall of the circular tube bracket. The cervical contraceptive device has reasonable structure and design. According to 3-year statistics of 265 cases of women of child-bearing age who use the device, symptoms of falling off, replacement, bleeding, infection, sore in waist, abdominal pain or intramural embedment and the like of the device never happen. The cervical contraceptive device provides a safe and reliable contraceptive device without side effects or complicating diseases for women of child-bearing age.

The invention relates to contraceptive apparatuses, in particular to a reversible drug-loaded fallopian tube contraceptive device which comprises a contraceptive device body. The reversible drug-loaded fallopian tube contraceptive device is characterized in that the inside of the contraceptive device body is latticed and hollow, muscone is contained in the contraceptive device body, and the surface of the contraceptive device body is evenly provided with micro pores. The muscone is loaded on the contraceptive device body to achieve the aim of long-time contraception, and the reversible drug-loaded fallopian tube contraceptive device can prevent ectopic gestation and endometriosis, can control gynecologic inflammation and tumors, resists to premature senility, delays premature climacteric, and achieves the aims of enhancing organism immunity and maintaining female reproductive health.

The invention discloses an antibacterial polyethylene composite material for a contraceptive device and a preparation method thereof. The antibacterial polyethylene composite material comprises the following components in parts by weight: 70-90 parts of polyethylene; 0.5-5 part of a copper-containing slow release material; 5-29 parts of an inorganic filler; and 0.01-1 part of an antioxidant. According to the antibacterial polyethylene composite material for the contraceptive device, carboxyl in macromolecule polybasic acid reacts with amino of chitosan, chitosan molecular chains are cross-linked through covalent bonds, copper ions are introduced to form a carboxyl and amino binary complex copper ion structure, the structural stability is high, the release rate of the copper ions is reduced, the guarantee is provided for the slow release of copper ions, and thus the chemical stability and the biocompatibility of the composite material are improved.

Methods for treating or reducing the risk of transmission of chlamydia to a recipient by topically applying a metalloprotease inhibitor to a site on the recipient which is likely to be exposed to Chlamydia. Topical compositions containing metalloprotease inhibitors are also disclosed for treating or reducing the risk of transmission of Chlamydia, as well as barrier contraceptive devices coated therewith.
