Essure
Essure was a device for female sterilization. It is a metal coil which when placed into each fallopian tube induces fibrosis and blockage.Free full text Essure was designed as an alternative to tubal ligation. However, it was recalled by Bayer in 2018, and the device is no longer sold due to complications secondary to its implantation. The company has reported that several patients implanted with the Essure System for Permanent Birth Control have experienced and/or reported adverse effects, including: perforation of the uterus and/or fallopian tubes, identification of inserts in the abdominal or pelvic cavity, persistent pain, and suspected allergic or hypersensitivity reaction. Although designed to remain in place for a lifetime, it was approved based on short-term safety studies. Of the 745 women with implants in the original premarket studies, 92% were followed up at one year, and 25% for two years, for safety outcomes. A 2009 review concluded that Essure appeared safe and eff ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conceptus Inc
Conceptus Inc. was an American medical products manufacturer and developer. It is now a fully owned subsidiary of Bayer AG of Germany. Founded in 1992, the corporation is headquartered in Mountain View, California. The company began development of micro-catheter and guidewire systems that allowed physicians to access and navigate the fallopian tubes using a non-incisional approach. While this technology was first used in products to diagnose or treat infertility, in 1998, the company focused on the design, development, and clinical testing of Essure, a non-incisional alternative to tubal ligation. Essure showed promise by eliminating the cutting, clipping, and burning associated with tubal ligation. After clinical testing, Conceptus began marketing Essure commercially in Australia, Singapore, Europe, and Canada. In 2002, the US Food and Drug Administration approved the use of Essure in the United States The United States of America (U.S.A. or USA), commonly known as th ...

Female Sterilization
Tubal ligation (commonly known as having one's "tubes tied") is a surgical procedure for female sterilization in which the fallopian tubes are permanently blocked, clipped or removed. This prevents the fertilization of eggs by sperm and thus the implantation of a fertilized egg. Tubal ligation is considered a permanent method of sterilization and birth control. Medical uses Female sterilization through tubal ligation is primarily used to permanently prevent a patient from having a spontaneous pregnancy (as opposed to pregnancy via in vitro fertilization) in the future. While both hysterectomy (the removal of the uterus) or bilateral oophorectomy (the removal of both ovaries) can also accomplish this goal, these surgeries carry generally greater health risks than tubal ligation procedures. Less commonly, tubal ligation procedures may also be performed for patients who are known to be carriers of mutations in genes that increase the risk of ovarian and fallopian tube cancer, s ...

The Bleeding Edge
''The Bleeding Edge'' is a 2018 Netflix original documentary film that investigates the $400 billion medical device industry. Written and directed by Kirby Dick and produced by Amy Ziering and Amy Herdy, it premiered at the 2018 Tribeca Film Festival, where it was billed as "the stuff of dystopian nightmares". It was released on July 27, 2018 on Netflix. Synopsis In ''The Bleeding Edge'', Academy Award-nominated investigative filmmakers Kirby Dick and Amy Ziering turn their sights on the $400 billion medical device industry; examining lax regulations, corporate cover-ups, and profit-driven incentives that put patients at risk daily. Weaving emotionally powerful stories of people whose lives have been irrevocably harmed, it asks: What lifesaving technologies may actually be killing us? According to the director: "Very few people know about the medical device industry and the fact that it is even less regulated than pharmaceuticals". The film explores the process of regulating me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birth Control
Birth control, also known as contraception, anticonception, and fertility control, is the use of methods or devices to prevent unwanted pregnancy. Birth control has been used since ancient times, but effective and safe methods of birth control only became available in the 20th century. Planning, making available, and using birth control is called family planning. Some cultures limit or discourage access to birth control because they consider it to be morally, religiously, or politically undesirable. The World Health Organization and United States Centers for Disease Control and Prevention provide guidance on the safety of birth control methods among women with specific medical conditions. The most effective methods of birth control are sterilization by means of vasectomy in males and tubal ligation in females, intrauterine devices (IUDs), and implantable birth control. This is followed by a number of hormone-based methods including oral pills, patches, vaginal rings ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vagina
In mammals, the vagina is the elastic, muscular part of the female genital tract. In humans, it extends from the vestibule to the cervix. The outer vaginal opening is normally partly covered by a thin layer of mucosal tissue called the hymen. At the deep end, the cervix (neck of the uterus) bulges into the vagina. The vagina allows for sexual intercourse and birth. It also channels menstrual flow, which occurs in humans and closely related primates as part of the menstrual cycle. Although research on the vagina is especially lacking for different animals, its location, structure and size are documented as varying among species. Female mammals usually have two external openings in the vulva; these are the urethral opening for the urinary tract and the vaginal opening for the genital tract. This is different from male mammals, who usually have a single urethral opening for both urination and reproduction. The vaginal opening is much larger than the nearby urethral openi ...

Cervix
The cervix or cervix uteri (Latin, 'neck of the uterus') is the lower part of the uterus (womb) in the human female reproductive system. The cervix is usually 2 to 3 cm long (~1 inch) and roughly cylindrical in shape, which changes during pregnancy. The narrow, central cervical canal runs along its entire length, connecting the uterine cavity and the lumen of the vagina. The opening into the uterus is called the internal os, and the opening into the vagina is called the external os. The lower part of the cervix, known as the vaginal portion of the cervix (or ectocervix), bulges into the top of the vagina. The cervix has been documented anatomically since at least the time of Hippocrates, over 2,000 years ago. The cervical canal is a passage through which sperm must travel to fertilize an egg cell after sexual intercourse. Several methods of contraception, including cervical caps and cervical diaphragms, aim to block or prevent the passage of sperm through the cervic ...

Spermatozoon
A spermatozoon (; also spelled spermatozoön; ; ) is a motile sperm cell, or moving form of the haploid cell that is the male gamete. A spermatozoon joins an ovum to form a zygote. (A zygote is a single cell, with a complete set of chromosomes, that normally develops into an embryo.) Sperm cells contribute approximately half of the nuclear genetic information to the diploid offspring (excluding, in most cases, mitochondrial DNA). In mammals, the sex of the offspring is determined by the sperm cell: a spermatozoon bearing an X chromosome will lead to a female (XX) offspring, while one bearing a Y chromosome will lead to a male (XY) offspring. Sperm cells were first observed in Antonie van Leeuwenhoek's laboratory in 1677. Mammalian spermatozoon structure, function, and size Humans The human sperm cell is the reproductive cell in males and will only survive in warm environments; once it leaves the male body the sperm's survival likelihood is reduced and it may die, t ...

Polyester
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET). Polyesters include naturally occurring chemicals, such as in plants and insects, as well as synthetics such as polybutyrate. Natural polyesters and a few synthetic ones are biodegradable, but most synthetic polyesters are not. Synthetic polyesters are used extensively in clothing. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind and environmental resistance compared to plant-derived fibers. They are less fire-resistant and can melt when ignited. Liquid crystalline polyesters are among the first industrially used liquid crystal polymers. They are used for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hysterosalpingogram
Hysterosalpingography (HSG), also known as uterosalpingography, is a radiologic procedure to investigate the shape of the uterine cavity and the shape and patency of the Fallopian tubes. It is a special x-ray using dye to look at the womb (uterus) and Fallopian tubes. It injects a radio-opaque material into the cervical canal, and usually fluoroscopy with image intensification. A normal result shows the filling of the uterine cavity and the bilateral filling of the Fallopian tube with the injection material. To demonstrate tubal rupture, spillage of the material into the peritoneal cavity needs to be observed. Hysterosalpingography has vital role in treatment of infertility, especially in the case of fallopian tube blockage. Uses HSG is considered a diagnostic procedure. It is used in the workup of infertile females to assess the patency of fallopian tubes, assess the competency of the cervix or congenital abnormality of the uterus in multiple miscarriages, assess the patency ...

Nickel
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Titanium
Titanium is a chemical element with the symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
