Medical devices include machines, implants and instruments used in the field of medical care. Machines such as thermometers or X-Ray machines diagnose conditions or diseases. Few others like inhalers or pacemakers are used for treatment or prevention. United States stipulates that the government run FDA must approve a device before it can be sold in the market. This is because any manufactured device poses a threat of being defective or can cause a health risk. FDA will issue a recall in such cases.
When a patient makes use of a medical device at home, he or she must be educated about its directions of usage and precautions if any. The FDA is entrusted with the responsibility of monitoring adverse issues and events with medical devices. The FDA hence alerts public and health care professionals wherever needed to assure appropriate use of medical devices for the health and safety of patients. With the advent of technology, the FDA approves a set of newer medical devices every year.
