Public Company
A public company is a company whose ownership is organized via shares of stock which are intended to be freely traded on a stock exchange or in over-the-counter markets. A public (publicly traded) company can be listed on a stock exchange (listed company), which facilitates the trade of shares, or not (unlisted public company). In some jurisdictions, public companies over a certain size must be listed on an exchange. In most cases, public companies are ''private'' enterprises in the ''private'' sector, and "public" emphasizes their reporting and trading on the public markets. Public companies are formed within the legal systems of particular states, and therefore have associations and formal designations which are distinct and separate in the polity in which they reside. In the United States, for example, a public company is usually a type of corporation (though a corporation need not be a public company), in the United Kingdom it is usually a public limited company (plc), i ...

Endoscopy
An endoscopy is a procedure used in medicine to look inside the body. The endoscopy procedure uses an endoscope to examine the interior of a hollow organ or cavity of the body. Unlike many other medical imaging techniques, endoscopes are inserted directly into the organ. There are many types of endoscopies. Depending on the site in the body and type of procedure, an endoscopy may be performed by either a doctor or a surgeon. A patient may be fully conscious or anaesthesia, anaesthetised during the procedure. Most often, the term ''endoscopy'' is used to refer to an examination of the upper part of the human gastrointestinal tract, gastrointestinal tract, known as an esophagogastroduodenoscopy. For nonmedical use, similar instruments are called borescopes. History Adolf Kussmaul was fascinated by sword swallowers who would insert a sword down their throat without gagging. This drew inspiration to insert a camera, the next problem to solve was how to insert a source of light, as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belmont, Massachusetts
Belmont is a town in Middlesex County, Massachusetts. It is a western suburb of Boston, Massachusetts, United States; and is part of the Greater Boston metropolitan area. At the time of the 2020 U.S. Census, the town's population stood at 27,295, up 10.4% from 2010. History Belmont was established on March 10, 1849, by former citizens of, and land from the bordering towns of Watertown, to the south; Waltham, to the west; and Arlington, then known as West Cambridge, to the north. They also wanted a town where no one could buy or sell alcohol (alcohol is now legal to purchase in Belmont). The town was named after ''Bellmont'', the 200 acre (0.8 km2) estate of the largest donor to its creation, John Perkins Cushing. Cushing Square is named after him and what was left of his estate after it nearly burned to the ground became a Belmont Public Library branch. The easternmost section of the town, including the western portion of Fresh Pond, was annexed by Cambridge in 1880 in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur D
Arthur is a common male given name of Brythonic origin. Its popularity derives from it being the name of the legendary hero King Arthur. The etymology is disputed. It may derive from the Celtic ''Artos'' meaning “Bear”. Another theory, more widely believed, is that the name is derived from the Roman clan '' Artorius'' who lived in Roman Britain for centuries. A common spelling variant used in many Slavic, Romance, and Germanic languages is Artur. In Spanish and Italian it is Arturo. Etymology The earliest datable attestation of the name Arthur is in the early 9th century Welsh-Latin text ''Historia Brittonum'', where it refers to a circa 5th to 6th-century Briton general who fought against the invading Saxons, and who later gave rise to the famous King Arthur of medieval legend and literature. A possible earlier mention of the same man is to be found in the epic Welsh poem ''Y Gododdin'' by Aneirin, which some scholars assign to the late 6th century, though this is still a ma ...

Itzhak Bentov
Itzhak "Ben" Bentov (also ''Ben-Tov''; he, יצחק בנטוב; August 9, 1923 – May 25, 1979) was an Israeli American scientist, inventor, mystic and author. His many inventions, including the steerable cardiac catheter, helped pioneer the biomedical engineering industry. He was also an early proponent of what has come to be referred to as consciousness studies and authored several books on the subject. Bentov was killed in the crash of American Airlines Flight 191 shortly after takeoff from Chicago O'Hare Airport in 1979, which remains the worst non-terrorism-related aviation disaster to have taken place on US soil. Early life Bentov was born in Humenné, Czechoslovakia, in 1923. During World War II, his parents, his younger brother and sister were killed in Nazi concentration camps. He narrowly escaped being sent to the camps and moved to British Palestine, first living on the Shoval kibbutz in the Negev. Despite not having a university degree, Bentov joined the Isra ...

Subcutaneous Implantable Defibrillator (S-ICD)
Subcutaneous implantable cardioverter defibrillator, or S-ICD, is an implantable medical device for detecting and terminating ventricular tachycardia and ventricular fibrillation in patients at risk of sudden cardiac arrest. It is a type of implantable cardioverter defibrillator but unlike the transvenous ICD, the S-ICD lead is placed just under the skin, leaving the heart and veins untouched. The S-ICD was developed to reduce the risk of complications associated with transvenous leads. Potential complications, such as infections in the bloodstream and the need to remove or replace the leads in the heart, are minimised or entirely eliminated with the S-ICD system. Transvenous ICD (leads in the heart) Pros The generator is smaller than the S-ICD generator, which may result in a less visible implanted device. This could improve the time needed to get used to the implantable device, although this is subjective. The procedure can usually be done under local anesthesia and ligh ...

Implantable Cardioverter-defibrillator
An implantable cardioverter-defibrillator (ICD) or automated implantable cardioverter defibrillator (AICD) is a device implantable inside the body, able to perform defibrillation, and depending on the type, cardioversion and pacing of the heart. The ICD is the first-line treatment and prophylactic therapy for patients at risk for sudden cardiac death due to ventricular fibrillation and ventricular tachycardia. "AICD" was trademarked by the Boston Scientific corporation, so the more generic "ICD" is preferred terminology. Current device batteries last about six to ten years; with advances in technology (batteries with more capacity or potentially rechargeable batteries) it may be possible to increase this well past ten years. The lead (the electrical cable connecting the device to the heart) has a much longer average longevity but can incur various types of malfunction, specifically insulation failure or fracture of the conductor, and require replacement. The process o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cameron Health
Cameron Health was a medical device developer based in San Clemente, California, USA. Cameron Health had its European office, Cameron Health BV, in Arnhem, The Netherlands. The privately held company's focus was on a new generation of minimally invasive implantable cardioverter-defibrillator (ICD) which they called a Subcutaneous Implantable Defibrillator (S-ICD). Cameron Health's approach avoided implanting transvenous leads into the heart, which had been the usual procedure for cardiac devices. Instead, the Cameron ICD was entirely implanted outside the thoracic wall. In June 2012, Boston Scientific officially acquired Cameron Health for a total sum of $1.3 Billion, paid out incrementally as various revenue milestones were achieved. , Boston Scientific still markets the S-ICD system. Reasons for a minimally invasive approach Every ICD is designed to detect heart rhythms consistent with a catastrophic failure of the body's natural regulation of the heartbeat, which, untreated, co ...

Artery
An artery (plural arteries) () is a blood vessel in humans and most animals that takes blood away from the heart to one or more parts of the body (tissues, lungs, brain etc.). Most arteries carry oxygenated blood; the two exceptions are the pulmonary and the umbilical arteries, which carry deoxygenated blood to the organs that oxygenate it (lungs and placenta, respectively). The effective arterial blood volume is that extracellular fluid which fills the arterial system. The arteries are part of the circulatory system, that is responsible for the delivery of oxygen and nutrients to all cells, as well as the removal of carbon dioxide and waste products, the maintenance of optimum blood pH, and the circulation of proteins and cells of the immune system. Arteries contrast with veins, which carry blood back towards the heart. Structure The anatomy of arteries can be separated into gross anatomy, at the macroscopic level, and microanatomy, which must be studied with a microscop ...

Vascular Occlusion
Vascular occlusion is a blockage of a blood vessel, usually with a clot. It differs from thrombosis in that it can be used to describe any form of blockage, not just one formed by a clot. When it occurs in a major vein, it can, in some cases, cause deep vein thrombosis. The condition is also relatively common in the retina, and can cause partial or total loss of vision. An occlusion can often be diagnosed using Doppler sonography (a form of ultrasound). Some medical procedures, such as embolisation, involve occluding a blood vessel to treat a particular condition. This can be to reduce pressure on aneurysms (weakened blood vessels) or to restrict a haemorrhage. It can also be used to reduce blood supply to tumours or growths in the body, and therefore restrict their development. Occlusion can be carried out using a ligature; by implanting small coils which stimulate the formation of clots; or, particularly in the case of cerebral aneurysms, by clipping.

Drug-eluting Stent
A drug-eluting stent (DES) is a peripheral or coronary stent (a scaffold) placed into narrowed, diseased peripheral or coronary arteries that slowly release a drug to block cell proliferation. This prevents fibrosis that, together with clots (thrombi), could otherwise block the stented artery, a process called restenosis. The stent is usually placed within the peripheral or coronary artery by an interventional cardiologist or interventional radiologist during an angioplasty procedure. Drug-eluting stents in current clinical use were approved by the FDA after clinical trials showed they were statistically superior to bare-metal stents for the treatment of native coronary artery narrowings, having lower rates of major adverse cardiac events (usually defined as a composite clinical endpoint of death + myocardial infarction + repeat intervention because of restenosis). The first drug-eluting stents to be approved in Europe and the U.S. were coated with paclitaxel or an mTOR inhi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stent
In medicine, a stent is a metal or plastic tube inserted into the lumen of an anatomic vessel or duct to keep the passageway open, and stenting is the placement of a stent. A wide variety of stents are used for different purposes, from expandable coronary, vascular and biliary stents, to simple plastic stents that allow urine to flow between kidney and bladder. "Stent" is also used as a verb to describe the placement of such a device, particularly when a disease such as atherosclerosis has pathologically narrowed a structure such as an artery. A stent is different from a shunt. A shunt is a tube that connects two previously unconnected parts of the body to allow fluid to flow between them. Stents and shunts can be made of similar materials, but perform two different tasks. Stent types Etymology The current accepted origin of the word ''stent'' is that it derives from the name of an English dentist, Charles Thomas Stent (1807–1885), notable for his advances in the fi ...
