Risk/benefit ratio for a medical device manufacturers will be all the possible benefits of the device which would come along with a number of possible associated risks. These risks and benefits have to be reviewed and discussed at the starting of the project proposal and during clinical trials. A negative result during these clinical trials will have to be considered and trials should be continued to reduce the associated risks after looking at the benefits post success of the project. As the efforts are taken to reduce the risks, the product in itself gets better thereby increasing the product life cycle will increase. However, as time progresses new products with better benefits and lower risks would be replacing the products as time goes by.
