Edwards Lifesciences, a medical device company based in Irvine, Calif., recently added more and more bets on cardiac mitral transcatheter therapy. Edwards specializes in structural heart disease, dominates the US market for transcatheter valve replacement devices, and recently announced the acquisition of Israeli company Valtech Cardio for $690 million. Valtech has a product called the "CardiobandTM System" that repairs heart valves in a transcatheter manner. Cardiac transcatheter therapy is a technique for inserting a catheter from the surrounding blood vessels into the heart chamber and the large blood vessels. It can be used for minimally invasive treatment of structural heart disease and is even considered a "non-surgical" method. Edwards Lifesciences' previous acquisition of CardiAQ developed the world's first self-coordinating and self-anchoring technique for catheter-implanted mitral valve (TMVI). By the beginning of 2017, Edwards will deliver $340 million to Valtech in the form of stocks and cash, and will pay the remaining $350 million in a phased payment over the next ten years. The two parties did not disclose the form of periodic payment, but usually companies such as Edwards Lifesciences will regularly evaluate the acquired company after the acquisition, check the approval and compliance of new products, market income, etc., and decide through each test result. Whether to give the next grant. Valtech's CardiobandTM system, which is seen by Edwards Lifesciences “We are pleased to see that Edwards, a leading global medical device company, is eyeing the field of transcatheter treatment of structural heart disease. We believe this collaboration will allow Valtech's Cardioband products to fully address mitral regurgitation. The potential of the flow," said Amir Gross, CEO of Valtech Cardio. The left ventricle of patients with mitral regurgitation increases, leading to ventricular papillary muscle dysfunction, resulting in dysfunction of the mitral and mitral annulus. Eventually it can lead to poor heart valve leaflets, blood backflow, and even heart disease in severe cases. For patients with functional mitral regurgitation, Valtech's CardiobandTM system differs from traditional cardiac surgery in that it uses a transcatheter approach for filler reconstruction. The CardiobandTM system uses a technique of femoral vein puncture, in which a catheter is inserted through the femoral vein and through the diaphragm into the heart. In particular, the device for repairing the mitral annulus is tailored to each patient. Heart valve treatment by femoral vein puncture
We may have heard of the Dome Fixed Focus Camera/ Fixed Focus Dome Camera/ Fixed Focus Dome cameras/ Fixed Focus Digital Dome Camera/ Fixed Focus Dome Camera Amazon/ Fixed Focus Dome Camera CCTV, so what is the Dome Fixed Focus Camera? We know that the dome refers to the camera shape, so what about the Fixed Focus? Actually, the Fixed Focus refers to a type of the camera lens. Today let me introduce the camera lens for you.
Last time, I have introduced the camera lens and one classification for you. Today please let me introduce the 2nd classification for you---the classification according to the occasions.
In conclusion, we can choose rake the angle of the view into consideration according to our needs, when we choose a Dome Fixed Focus Camera.

1. The standard lens
The lens with the angle of view at about 50°(which is also the angle that a person can see without turning his head and eyes), is called the standard lens. The focal length of the 5mm camera's standard lens is mostly 40mm, 50mm or 55mm. The focal length of the 120 camera's standard lens is mostly 80mm or 75mm. The larger the CCD chip is, the longer the focal length of the standard lens will be.
2. The wide-angle lens
The wide-angle lens has the angle of view at above 90 degrees, which is suitable for shooting close and large-scale scenery, and can deliberately exaggerate the foreground to show a sense of perspective. The typical wide-angle lens of the 35mm camera has a focal length at 28mm and an angle of view at 72°. The 50mm, 40mm lens of the 120 camera is equivalent to the 35mm, 28mm lens of the 35mm camera.
3. The long focal length lens
The long focal length lens is suitable for shooting distant subjects. The small depth of field can easily make the background blurred and the subject stand out, but it is bulky and the difficult to focus on the dynamic subjects. The long focal length lenses of the 35mm camera are usually divided into three levels, 135mm or less is called the medium focal length, 135-500mm is called the long focal length, and above 500mm is called the super long focal length. The 150mm lens of the 120 camera is equivalent to the 105mm lens of the 35mm camera. The long focal length lens has the telephoto lens design because it is too bulky, that is, a negative lens is added to the lens behind , and the main plane of the lens is moved forward, then a shorter lens body can be used to obtain the long focal length effect.
4. The reflective telescope lens
The reflective telescope lens is another design of the super telescope lens, which uses a reflecting mirror to form an image. However, due to the design, the aperture can't be installed, and the exposure can be adjusted only through the shutter.
5. The Macro lens
The Macro lens can not only do the close-up macro photography, but also do the telephoto.
