ReliantHeart Inc
ReliantHeart, Inc. is a privately held American company headquartered in Houston, Texas that designs, manufactures, and provides remote monitoring capabilities for its left ventricular assist devices (LVAD, or VAD) which are used to assist circulation for failing hearts. History The original VAD was developed by David Saucier, a heart transplant patient who worked at NASA, and surgeon Michael DeBakey. Dallas W. Anderson, who founded MicroMed Technology Inc. in 1995, was granted exclusive rights to the NASA/DeBakey VAD in 1996. MicroMed Cardiovascular, Inc. filed for Chapter 11 bankruptcy in June 2013, and former members of the company founded ReliantHeart Inc. in August 2013. ReliantHeart became successor-in-interest to the assets of MicroMed Cardiovascular, Inc., including the HeartAssist5 VAD. In August 2014, ReliantHeart purchased 50% of INRTracker, an online tool for patients taking Warfarin and reporting of INR. Products The HeartAssist5 is a modern version of the De ...

Privately-held
A privately held company (or simply a private company) is a company whose shares and related rights or obligations are not offered for public subscription or publicly negotiated in the respective listed markets, but rather the company's stock is offered, owned, traded, exchanged privately, or over-the-counter. In the case of a closed corporation, there are a relatively small number of shareholders or company members. Related terms are closely-held corporation, unquoted company, and unlisted company. Though less visible than their publicly traded counterparts, private companies have major importance in the world's economy. In 2008, the 441 largest private companies in the United States accounted for ($1.8 trillion) in revenues and employed 6.2 million people, according to ''Forbes''. In 2005, using a substantially smaller pool size (22.7%) for comparison, the 339 companies on ''Forbes'' survey of closely held U.S. businesses sold a trillion dollars' worth of goods and services (4 ...

Coins Of The United States Dollar
Coins of the United States dollar (aside from those of the earlier Continental currency) were first minted in 1792. New coins have been produced annually and they make up a valuable aspect of the United States currency system. Today, circulating coins exist in denominations of 1¢ (i.e. 1 cent or $0.01), 5¢, 10¢, 25¢, 50¢, and $1.00. Also minted are bullion (including gold, silver and platinum) and commemorative coins. All of these are produced by the United States Mint. The coins are then sold to Federal Reserve Banks which in turn are responsible for putting coins into circulation and withdrawing them as demanded by the country's economy. Current coinage Today, four mints operate in the United States producing billions of coins each year. The main mint is the Philadelphia Mint, which produces circulating coinage, mint sets and some commemorative coins. The Denver Mint also produces circulating coinage, mint sets and commemoratives. The San Francisco Mint produces regu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forward Compatibility
Forward compatibility or upward compatibility is a design characteristic that allows a system to accept input intended for a later version of itself. The concept can be applied to entire systems, electrical interfaces, telecommunication signals, data communication protocols, file formats, and programming languages. A standard supports forward compatibility if a product that complies with earlier versions can " gracefully" process input designed for later versions of the standard, ignoring new parts which it does not understand. The objective for forward compatible technology is for old devices to recognise when data has been generated for new devices. Forward compatibility for the older system usually means backward compatibility for the new system, i.e. the ability to process data from the old system; the new system usually has ''full'' compatibility with the older one, by being able to both process and generate data in the format of the older system. Forward compatibility is no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Machine To Machine
Machine to machine (M2M) is direct communication between devices using any communications channel, including wired and wireless. Machine to machine communication can include industrial instrumentation, enabling a sensor or meter to communicate the information it records (such as temperature, inventory level, etc.) to application software that can use it (for example, adjusting an industrial process based on temperature or placing orders to replenish inventory). Such communication was originally accomplished by having a remote network of machines relay information back to a central hub for analysis, which would then be rerouted into a system like a personal computer. More recent machine to machine communication has changed into a system of networks that transmits data to personal appliances. The expansion of IP networks around the world has made machine to machine communication quicker and easier while using less power. These networks also allow new business opportunities for consum ...

Ventricle (heart)
A ventricle is one of two large chambers toward the bottom of the heart that collect and expel blood towards the peripheral beds within the body and lungs. The blood pumped by a ventricle is supplied by an atrium, an adjacent chamber in the upper heart that is smaller than a ventricle. Interventricular means between the ventricles (for example the interventricular septum), while intraventricular means within one ventricle (for example an intraventricular block). In a four-chambered heart, such as that in humans, there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs, and the left ventricle pumps blood into the systemic circulation through the aorta. Structure Ventricles have thicker walls than atria and generate higher blood pressures. The physiological load on the ventricles requiring pumping of blood throughout the body and lungs is much greater than the pressure generated by the atria ...

Euro Coins
There are eight euro coin denominations, ranging from one cent to two euros (the euro is divided into a hundred cents). The coins first came into use in 2002. They have a common reverse, portraying a map of Europe, but each country in the eurozone has its own design on the obverse, which means that each coin has a variety of different designs in circulation at once. Four European microstates that are not members of the European Union (Andorra, Monaco, San Marino, and the Vatican City) use the euro as their currency and also have the right to mint coins with their own designs on the obverse side. The coins, and various commemorative coins, are minted at numerous national mints across the European Union to strict national quotas. Obverse designs are chosen nationally, while the reverse and the currency as a whole is managed by the European Central Bank (ECB). History The euro came into existence on 1 January 1999. It had been a goal of the European Union (EU) and its predecessors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Axial Flow Pump
An axial-flow pump, or AFP, is a common type of pump that essentially consists of a propeller (an axial impeller) in a pipe. The propeller can be driven directly by a sealed motor in the pipe or by electric motor or petrol/diesel engines mounted to the pipe from the outside or by a right-angle drive shaft that pierces the pipe. Fluid particles, in course of their flow through the pump, do not change their radial locations since the change in radius at the entry (called 'suction') and the exit (called 'discharge') of the pump is very small. Hence the name "axial" pump. Operation An axial flow pump has a propeller-type of impeller running in a casing. The pressure in an axial flow pump is developed by the flow of liquid over the blades of impeller. The fluid is pushed in a direction parallel to the shaft of the impeller, that is, fluid particles, in course of their flow through the pump, do not change their radial locations. It allows the fluid to enter the impeller axially and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medical Devices
A medical device is any device intended to be used for medical purposes. Significant potential for hazards are inherent when using a device for medical purposes and thus medical devices must be proved safe and effective with reasonable assurance before regulating governments allow marketing of the device in their country. As a general rule, as the associated risk of the device increases the amount of testing required to establish safety and efficacy also increases. Further, as associated risk increases the potential benefit to the patient must also increase. Discovery of what would be considered a medical device by modern standards dates as far back as c. 7000 BC in Baluchistan where Neolithic dentists used flint-tipped drills and bowstrings. Study of archeology and Roman medical literature also indicate that many types of medical devices were in widespread use during the time of ancient Rome. In the United States it wasn't until the Federal Food, Drug, and Cosmetic Act (FD& ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Destination Therapy
Destination therapy is a therapy that is final rather than being a transitional stage until another therapy—thus, in transportation metaphor, a destination in itself rather than merely a bridge or road to the destination. The term usually refers to ventricular assist devices or mechanical circulatory support to keep the existing heart going, not just until a heart transplant can occur, but for the rest of the patient's life expectancy. It is thus a course of treatment for severe (e.g., NYHA class IV/ACC stage D) heart failure patients who are not likely candidates for transplant. In contrast, bridge-to-transplant therapy is a way to stay alive long enough, and stay healthy enough, to await transplant while maintaining eligibility for transplant. Heart failure is a leading cause of death in industrialized economies. Among those with serious heart illness some are, for a variety of possible medical circumstances, ineligible for a heart transplant. Destination therapy provides a ...

Warfarin
Warfarin, sold under the brand name Coumadin among others, is a medication that is used as an anticoagulant (blood thinner). It is commonly used to prevent blood clots such as deep vein thrombosis and pulmonary embolism, and to prevent stroke in people who have atrial fibrillation, valvular heart disease, or artificial heart valves. Less commonly, it is used following ST-segment elevation myocardial infarction and orthopedic surgery. It is generally taken by mouth, but may also be used intravenously. The common side effect is bleeding. Less common side effects may include areas of tissue damage and purple toes syndrome. Use is not recommended during pregnancy. The effects of warfarin typically should be monitored by checking prothrombin time (INR) every one to four weeks. Many other medications and dietary factors can interact with warfarin, either increasing or decreasing its effectiveness. The effects of warfarin may be reversed with phytomenadione (vitamin K1), fresh f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
