Hyping up a product is an important factor in producing a successful medical product release. Good information must be released in order to increase sale and so that the public will buy it. Companies do this by coming into hospitals and offering their devices to people in need so they can test it out. This helps them have advertisers or users who have first-hand account of their experience with their device so that they can share it and attract more users. They can also attend conferences and presentations to showcase their product to make the market aware of its existence.
