The Present and the Future of Pacemakers that are MRI Compatible

A pacemaker is a device that is surgically implanted into a patient's chest or abdomen to help control abnormal heart rhythms. This device uses electric pulses to beat the heart at a normal rate. Cardiac pacemakers are used to treat arrhythmias, an irregular or fast heartbeat. It is composed of two components, such as lead and generator. However, pacemakers are regarded as high-risk medical devices by the United States Food and Drug Administration (FDA). Thus, these devices undergo rigorous safety and efficacy tests prior to receiving approval. In the United States, several medical device companies have received FDA approval and have launched pacemakers that are MRI compatible.

In the past, Magnetic resonance imaging (MRI) was not allowed in patients with implanted cardiac pacemakers. However, technological advances have made it possible thanks to the research efforts of several physicians and researchers. MRI can now be safely performed in many patients with cardiac pacemakers. Now, several medical device companies have developed pacemakers that are MRI compatible. For instance, Japan approved the use of a leadless pacemaker. It is designed to be implanted through a catheter in the right ventricle to deliver single-chamber pacing. Moreover, Germany was one of the first countries to adopt pacemakers, and successful operations have been taking place in Germany for over 50 years.

Pacemakers have been used for years to treat cardiac arrhythmia and heart disease. However, with advancements in technology, many people now find that they have the ability to enjoy the comfort of having their pacemaker permanently placed in their bodies. A pacemaker basically replaces and/or modifies the normal function of the cardiac conduction system of the body. The pacemaker is basically designed to monitor and correct the malfunctioning of a heart's electrical circuits. The main purpose of these newer pacemakers is to replace the existing heart pacemakers or those patients who cannot have a pacemaker as they are diagnosed with severe heart diseases, such as coronary artery disease or myocardial infarction.

Pregnancy Testing Devices are proving to be revolutionary tool with hassle-free testing and rapid results

Image
Pregnancy Testing Devices are medical devices that aid in identifying the potential of pregnancy. It is mostly used by pregnant women for determining the exact time they missed their periods. Pregnancy Testing Devices come in different types like basal body membrane technique (BBMT), digital analysis, embryo transfer method (ETM), ultrasonic Doppler microform method (UDM), and hysterosalpingogram (HSG). Pregnancy Testing Devices is also calling pregnancy test kits.  They can also be termed as basal body membrane technique test kits. Pregnancy test kits are available in various online stores at affordable prices. The most common one is kits for basal body membrane technique (BBMT) and digital analysis. BBMT uses a wet mount for conducting the test whereas digital analysis requires no dry mounts. Some of the other methods of analyzing pregnancy tests include determining the LH level, HCG level, sugar level, cervical mucus, and viral detection. A pregnancy test can also be used for d...

Liquid Crystal Polymers are witnessing wide range of applications as Industry Leaders in Japan Develop Novel LCP Products

Image
Liquid crystal polymers (LCPs) are a category of aromatic polymers that are extremely inert and unreactive and also highly resistant to fire. LCPs are mainly useful in mechanical and electrical parts, food containers, and also other applications where chemical inertness is necessary. They are also used in plug connectors, transmission system components, lamp sockets, pump sockets, and sunlight sensors. The most recent technology to emerge as one of the most sought after polymeric materials is the LCD or Liquid Crystal Display.  This technology is now used in almost every commercial production process from the initial manufacturing stage right through to the final display unit of an electronic display. Liquid crystal polymers are currently used in the construction industry and are widely available as a wide range of goods. Polypropylene, polystyrene, and polyimide are popular building material which use these compounds to make various products including insulation, plastic, insulati...

Polydimethylsiloxane (PDMS): A Member of Polymeric Organosilicon Compounds Used In Various Industries Due To Its Versatility and Properties

Image
Polydimethylsiloxane (PDMS) is a compound that is commonly used for the development of contact lenses, but it has many other uses as well. Surfactants and foaming agents are among the many things that are made from PDMS. Other uses include, the treatment of petroleum jelly and rubber. The chemicals used in the manufacture of cosmetics and medicines may also be derived from PDMS. The production facilities for PDMS in Europe are located in France, Germany and the U.K. In Germany, PDMS is classified as “slightly water polluting”. It was not that long ago that scientists thought there might be some connection between the use of polydimethylsiloxane in cosmetics and the development of allergic reactions. Scientists have since conducted studies and discovered that there actually are connections between the use of this chemical agent and the development of eczema and allergic reactions. The link between cosmetics and skin irritation and allergy is a result of the fact that the ingredients in...
